<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结构简析</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9CloyfF2iae5ojozvK81SC3BByXpL3btEEUW7t8Ne4gAnYXndTGAGkhQ/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">结构方面，Micromatic 777集成度非常高，可无损拆解出的零件很少，还是分成夹芯结构与拉芯结构两大部分。</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a91VqjIWRLknoULCOxlia2ia5T0LukCTVRB9wDpHZb2ia06QI21p8BFjLfQ/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">夹芯结构<span style="color: black;">所有</span>集成于一个外壳之内，很难拆解。拉芯结构<span style="color: black;">一样</span>如此，只能依据一篇美国专利（USP 4538934）进行下一步分析。</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9Oyv5hHuU85QiboP60eg0by2j0TkKu80heS4wUKhqpgeVxdlZLon9ldQ/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">上图即为专利中施德楼Micromatic 777结构的原型，<span style="color: black;">实质</span><span style="color: black;">制品</span>与之稍有改动。</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a925rv98ucOl4go2sqDuerVeFyiaJoYwvTpbZp7kb1jfrLbtAJ3KL33SA/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9UHgXDPEqBbNc3YicL4MzciaZZoPPAkTezp7A8Dya0Y7QNQuCYGr3WGng/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9xcztEYmmXgLqiaLbA1icH9Mvdrqkaz8EKlKtX87ibvmCxc0yuZPDxEJ8Q/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a97Vybh18OyC0UTXRGoHcNMgp9CAcmBffKAUrB90JnazWhdhXeZialmYA/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9I6NbNFOHsMFHUC4iaiaU9wst7rmGpPhuU3mjCU1MgEFORRz2bwmJn9PQ/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Micromatic 777的拉芯头由两部分<span style="color: black;">构成</span>（21与25），其中零件21很长，与夹芯结构内部的零件相接触，其内壁为一金属管23，内壁<span style="color: black;">无</span>阻尼。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">零件25固定阻尼圈22与护芯管2。<span style="color: black;">全部</span>拉芯结构里<span style="color: black;">无</span>弹簧，<span style="color: black;">况且</span>护芯管几乎<span style="color: black;">能够</span>完全缩入尖套（如图）。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">另外</span>，Micromatic 777有可能在尖套与拉芯结构之间设置阻尼26，以尽可能<span style="color: black;">保准</span><span style="color: black;">运用</span>时护芯管不会回缩。<span style="color: black;">不外</span>在<span style="color: black;">实质</span>体验中，略微有种类似于PN3015的笔头自锁功能，<span style="color: black;">不外</span>文献中并未给出实现<span style="color: black;">办法</span>，<span style="color: black;">亦</span>很<span style="color: black;">经过</span>难拆解确定。</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9RxPxQaXlibdybo5JfhuiaDhaa1wqG7HiaHE0qRpyB5O5M3ic4Hk7f0ibFJg/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a93QgBAzPtrQMQl6MTXCzApk6QGu58Y5wQDu6NmEAwlBllKSmLofT5vw/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9mO3racGubQ4G14l0Ws31LGqt3n5GI1kOvUxu2FaEYyla8bRoSDCaSQ/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">关于Micromatic 777的夹芯结构，与<span style="color: black;">通常</span>的自动<span style="color: black;">赔偿</span>式铅笔的自锁夹芯结构<span style="color: black;">区别</span>（图2），其内部<span style="color: black;">无</span>卡头弹簧，<span style="color: black;">因此呢</span>，二开花卡头（零件40）在平常<span style="color: black;">处在</span>松弛状态。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">另外</span>，还有一个零件61（图3看到的机芯内部的塑料零件），上面固定有零件67（零件61中间那个金属圈），零件61<span style="color: black;">经过</span>压缩弹簧60与二开花卡头固定。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">不仅如此，卡头还向外展出两翼金属“片”（序号45或46，图3中塑料零件61与机芯外壳之间那<span style="color: black;">一起</span>，专利中的命名叫止动爪），用来对零件61限位，<span style="color: black;">同期</span>零件61借此<span style="color: black;">保准</span>二开花卡头张开。<span style="color: black;">因此呢</span>，当维持护芯管与尖套相对位置不变时，<span style="color: black;">能够</span>推入铅芯。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">实质</span>中的施德楼777，其卡头、压缩弹簧等零件被外壳完全包裹封装，而专利中这些零件是外露的。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">功能分析</p><img src="https://mmbiz.qpic.cn/mmbiz_jpg/bSYsxjv0gjiaT2ib37R1tA3lhB4pNW19a9hxoTFwiadaukPdpIrVAJbb526ic2s6a0LGWPynSPk16R2Kt3iczbSGRwA/640?wx_fmt=jpeg&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Micromatic 777有两种出铅方式。一种是用于送出铅芯至与护芯管平齐：摇动几下后，轻轻揿入十余次，<span style="color: black;">就可</span>出铅。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">查阅以往的专利文献，这种设计思想很早就有，但Micromatic 777应是首家实现量产的，以后会开专文介绍。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">还有一种用于将铅芯送出一截，这种方式类原理类似PN3015。这种需要笔尖倾斜<span style="color: black;">必定</span><span style="color: black;">方向</span>，<span style="color: black;">而后</span>再完全揿入护芯管再松手弹出，会带出一截铅芯。</p><img src="data:image/svg+xml,%3C%3Fxml version=1.0 encoding=UTF-8%3F%3E%3Csvg width=1px height=1px viewBox=0 0 1 1 version=1.1 xmlns=http://www.w3.org/2000/svg xmlns:xlink=http://www.w3.org/1999/xlink%3E%3Ctitle%3E%3C/title%3E%3Cg stroke=none stroke-width=1 fill=none fill-rule=evenodd fill-opacity=0%3E%3Cg transform=translate(-249.000000, -126.000000) fill=%23FFFFFF%3E%3Crect x=249 y=126 width=1 height=1%3E%3C/rect%3E%3C/g%3E%3C/g%3E%3C/svg%3E" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">第1</span>种<span style="color: black;">办法</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（1）摇晃几下，铅芯<span style="color: black;">就可</span>自然下坠，落入松弛的卡头套管，铅芯头部将会<span style="color: black;">处在</span>零件22上方的倒角内。此时揿动笔尖护芯管，<span style="color: black;">首要</span>是零件23从尖套31内部的台阶向上抬起，抵抗弹簧60的弹力向后推动止动爪，压紧二开花卡头40，使铅芯不能向后滑动。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（2）继续揿入一段护芯管，<span style="color: black;">因为</span>铅芯此时被卡头抓紧，<span style="color: black;">不可</span>自由活动。零件22（阻尼）利用摩擦夹住一段铅芯。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（3）抬起笔尖后，零件21等拉芯结构在弹簧60的弹力下向前移动，此时阻尼圈22就带出此前夹住的一段铅芯。多次揿动之后，就将铅芯完全带出来。</p><img src="data:image/svg+xml,%3C%3Fxml version=1.0 encoding=UTF-8%3F%3E%3Csvg width=1px height=1px viewBox=0 0 1 1 version=1.1 xmlns=http://www.w3.org/2000/svg xmlns:xlink=http://www.w3.org/1999/xlink%3E%3Ctitle%3E%3C/title%3E%3Cg stroke=none stroke-width=1 fill=none fill-rule=evenodd fill-opacity=0%3E%3Cg transform=translate(-249.000000, -126.000000) fill=%23FFFFFF%3E%3Crect x=249 y=126 width=1 height=1%3E%3C/rect%3E%3C/g%3E%3C/g%3E%3C/svg%3E" style="width: 50%; margin-bottom: 20px;"><img src="data:image/svg+xml,%3C%3Fxml version=1.0 encoding=UTF-8%3F%3E%3Csvg width=1px height=1px viewBox=0 0 1 1 version=1.1 xmlns=http://www.w3.org/2000/svg xmlns:xlink=http://www.w3.org/1999/xlink%3E%3Ctitle%3E%3C/title%3E%3Cg stroke=none stroke-width=1 fill=none fill-rule=evenodd fill-opacity=0%3E%3Cg transform=translate(-249.000000, -126.000000) fill=%23FFFFFF%3E%3Crect x=249 y=126 width=1 height=1%3E%3C/rect%3E%3C/g%3E%3C/g%3E%3C/svg%3E" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">第二种<span style="color: black;">办法</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（1）（2）步与<span style="color: black;">第1</span>种<span style="color: black;">办法</span>过程相同。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（3）之后，护芯管进一步后移，此时弹簧60<span style="color: black;">已然</span><span style="color: black;">无</span>压缩空间，以此推动动<span style="color: black;">全部</span>夹芯结构后移，使得压缩弹簧96压缩（<span style="color: black;">能够</span>拆出来那个弹簧）。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（4）<span style="color: black;">因为</span>笔尖倾斜<span style="color: black;">必定</span><span style="color: black;">方向</span>，且承受<span style="color: black;">必定</span>压力，<span style="color: black;">或</span>笔头内部设置了<span style="color: black;">公司</span>。<span style="color: black;">因此呢</span>，拉芯结构与尖套形成前文所述的自锁。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">松开后，压缩弹簧96回弹，带动前面各零件<span style="color: black;">公司</span>前移，护芯管先会推出一部分，当弹簧96弹力<span style="color: black;">少于</span>自锁摩擦力且大于阻尼圈摩擦力时，护芯管不动，推出一部分铅芯。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">（5）此后夹芯结构机芯复位，之后<span style="color: black;">过程</span>同<span style="color: black;">第1</span>种<span style="color: black;">办法</span>（3）。</p>
