Description

全自动铅笔
技术领域
本发明涉及一种铅笔,尤其是一种全自动铅笔。
背景技术
普通自动铅笔一次只能装入1-2根铅笔芯,由于铅笔芯很细,容易折断,每次更换铅笔芯很麻烦。
发明内容
本发明的目的就是要提供一种一次可装入多根铅笔芯的全自动铅笔。
本发明的目的是这样实现的:一种全自动铅笔,包括笔杆、笔尖和按钮,笔杆内一端设有细塑管,笔杆内另一端设有硬塑管,硬塑管一端与细塑管一端连接,硬塑管一端与按钮连接,细塑管一端与笔尖连接,硬塑管采用漏斗状。
本发明由于采用上述结构,将现有铅笔芯管加以改进,使其装入更多的铅笔芯,使用更方便。
附图说明
下面结合附图和具体实施方式作进一步说明。
图1是本发明的结构示意图。
具体实施方式
本发明的结构包括:一种全自动铅笔,包括笔杆1、笔尖2和按钮3,其特征在于:笔杆1内一端设有细塑管4,笔杆1内另一端设有硬塑管5,硬塑管5一端与细塑管4一端连接,硬塑管5一端与按钮3连接,细塑管4一端与笔尖2连接,硬塑管5采用漏斗状。
使用时将铅笔芯一次装入6-7根在硬塑管5里,当细塑管4里的笔芯用完一节时,硬塑管5里的笔芯会自动进入细塑管4中,如此循环。
