Abstract

本实用新型涉及一种伸缩式笔杆,包括中空的主笔杆,主笔杆上端套装有副笔杆,副笔杆的顶端通过螺纹连接有笔杆顶帽,所述的副笔杆的杆身上,沿竖直方向设有一排圆孔;主笔杆的上部固定一个凸点簧片,凸点簧片的凸点可卡入副笔杆的杆身上的圆孔中。使用时,旋开副笔杆上的笔杆顶帽,将过长的笔芯通过可升降副笔杆插入主笔杆中,将可升降副笔杆向上拉至与笔芯的顶端平齐,此时,主笔杆上的凸点簧片的凸点弹入副笔杆杆身上的一个圆孔中,使主笔杆与副笔杆相对定位,旋上笔杆顶帽,即可用此笔书写。使用伸缩式笔杆可以将一定长度范围内的笔芯正好放入笔杆内,从而解决了以往替换笔芯时,遇到笔杆太长或太短不能使用的问题。

Description

一种伸缩式笔杆
技术领域
本实用新型涉及一种伸缩式笔杆。
背景技术
现有的各种可替换笔芯的书写笔类型较多,所以,各种笔芯的长度是不相同的;当学生在替换笔芯时,经常会遇到笔杆过短或过长的问题,使等着急用笔的学生,感到困惑。
发明内容
本实用新型的目的是要提供一种结构合理的伸缩式笔杆,本实用新型所要解决的技术问题是通过以下的技术方案来实现的伸缩式笔杆,其特点是:包括中空的主笔杆,主笔杆上端套装有副笔杆,副笔杆的顶端通过螺纹连接有笔杆顶帽,所述的副笔杆的杆身上,沿竖直方向设有一排圆孔;主笔杆的上部固定一个凸点簧片,凸点簧片的凸点可卡入副笔杆的杆身上的圆孔中。
使用时,旋开副笔杆上的笔杆顶帽,将过长的笔芯通过可升降副笔杆插入主笔杆中,将可升降副笔杆向上拉至与笔芯的顶端平齐,此时,主笔杆上的凸点簧片的凸点弹入副笔杆杆身上的一个圆孔中,使主笔杆与副笔杆相对定位,旋上笔杆顶帽,即可用此笔书写。
使用伸缩式笔杆可以将一定长度范围内的笔芯正好放入笔杆内,从而解决了以往替换笔芯时,遇到笔杆太长或太短不能使用的问题。
附图说明
图1是伸缩式笔杆的结构示意图。
具体实施方式
参照图1,一种伸缩式笔杆,包括中空的主笔杆4,主笔杆4上端套装有副笔杆2,副笔杆2的顶端通过螺纹连接有笔杆顶帽1,所述的副笔杆2的杆身上,沿竖直方向设有一排圆孔5;主笔杆4的上部固定一个凸点簧片3,凸点簧片3的凸点可卡入副笔杆2的杆身上的圆孔5中。
