Description

自动笔
（一）技术领域：
本发明涉及一种文具，具体的说是一种自动笔。
（二）背景技术：
本发明在使用时出芯方式实现了顿笔出芯，使用者握住外筒（5）点顿笔尖，可以实现对笔芯的移动的控制。
以往的同类品在使用时把笔芯填装在中筒（4）里面，也就是说把笔芯和顶芯（2）填装在同一个通道里，这主要产生了两个问题：①若从尾部填装笔芯，必须把顶芯（2）取出。②所使用的笔芯必须和顶芯（2）等粗。本发明很好的解决了这两个问题。使用者使用时若从笔的后端填装笔芯，不必取出顶芯（2）。本发明所使用的笔芯可以比顶芯（2）细。
（三）发明内容：
本自动笔所使用的笔芯包含粉笔、铅笔、蜡笔、橡皮。
内管（10）设有纵向槽。
所使用的笔芯填装在内管（10）内。
顶芯（2）设有卡头（3）和爪（11）。
顶芯（2）套在内管（10）外面，爪（11）透过内管（10）的纵向槽固定住内管（10）内的笔芯。
内筒（1）设有纵向槽。
内筒（1）套在顶芯（2）外面。卡头（3）卡在内筒（1）的纵向槽内。
中筒（4）设有螺旋槽。
中筒（4）套在内筒（1）外面。卡头（3）透过内筒（1）的纵向槽卡在中筒（4）的螺旋槽里。
中筒（4）的旋转可以带动卡头（3）沿内筒（1）的纵向槽发生移动，从而带动顶芯（2）发生移动，于是实现了笔芯的移动。
中筒（4）设有前齿（6）和后齿（7）。
外筒（5）设有前顶齿（8）和后顶齿（9）。
外筒（5）套在中筒（4）的外面。
当使用者使外筒（5）向前移动时，外筒（5）的后顶齿（9）与中筒（4）的后齿（7）发生接触，此接触使中筒（4）发生旋转。
然后使用者使外筒（5）向后移动，外筒（5）的前顶齿（8）与中筒（4）的前齿（6）发生接触，此接触使中筒（4）发生旋转。
中筒（4）的旋转带动顶芯（2）在内筒（1）内移动，从而实现笔芯在内管（10）内的移动。
（四）附图说明：
图1是自动笔整体外观正面视图。图中（1）是内筒，（4）是中筒，（5）是外筒，（10）是内管。
图2是自动笔整体外观90度角侧视图。图中（1）是内筒，（4）是中筒，（5）是外筒，（10）是内管。
图3是自动笔整体外观俯视图。图中（1）是内筒，（4）是中筒，（5）是外筒，（10）是内管。
图4是拆散后的所有零件。图中（1）是内筒，（2）是顶芯，（4）是中筒，（5）是外筒，（10）是内管。
图5是外筒（5）的外观图。
图6是外筒（5）的纵剖图。图中（8）是前顶齿，（9）是后顶齿。
图7是中筒（4）的外观图。图中（6）是前齿，（7）是后齿。
图8是中筒（4）的俯视图。
图9是中筒（4）的纵剖图。图中（6）是前齿，（7）是后齿。
图10是内筒（1）的外观图。
图11是内筒（1）的俯视图。
图12是内管（10）的外观图。
图13是顶芯（2）的外观图。图中（3）是卡头，（11）是爪。
图14是内筒（1）、顶芯（2）、内管（10）组合在一起后的正面效果图。图中（3）是卡头。
图15是内筒（1）、顶芯（2）、内管（10）组合在一起后的侧面效果图。图中（3）是卡头。
图16是将外筒（5）纵剖之后的效果图。此时是自动笔书写时的状态。
图17是将外筒（5）纵剖之后的效果图。此时是外筒（5）向前移动时的状态，后顶齿（9）和后齿（7）发生接触，将使中筒（4）发生旋转。
图18是将外筒（5）纵剖之后的效果图。此时是外筒（5）向后移动时的状态，前顶齿（8）和前齿（6）发生接触，将使中筒（4）发生旋转。
图19是将外筒（5）纵剖之后的效果图。此时是外筒（5）向后移动结束时的状态，中筒（4）已发生旋转。
（五）具体实施方式：
顶芯（2）退到笔尾，爪（11）张开，这时可以将新笔芯从笔的后端装入内管（10）。从笔的后端填装笔芯，其优点在于可以不必取出残笔芯，装入新笔芯后残笔芯仍然可以继续使用，从而达到笔芯的最佳使用率。
使用者使用时可以点顿笔尖，笔芯相对于外筒（5）向后移动，笔芯移动带动顶芯（2）移动，顶芯（2）带动中筒（4）移动，通过齿和顶齿之间的相互作用，此移动使中筒（4）发生旋转，从而实现了笔芯的移动。
