Abstract

一种简单节约型铅笔套管,其特征是:空心管横截面为圆形或正六边形。1根非常短的铅笔头+1根空心的铅笔管=1支长的铅笔,只要加上这样的铅笔管,铅笔就可以套在里面,不至于因为笔短无法用手握住而浪费掉了。

Description

一种简单节约型铅笔套管
技术领域
本实用新型涉及一种简单节约型铅笔套管,属于文具技术领域。 
背景技术
目前铅笔使用至较短时,无法手握其顺利写字,绝大多数人会将其丢弃,造成近三分之一的铅笔浪费。现在还没有一种结构简单且可将铅笔充分使用的装置供人们使用。 
发明内容
为了弥补现有技术中的不足,本实用新型提供了一种简单节约型铅笔套管,适用于较短铅笔的相互连接,减少浪费的短铅笔套管。 
本实用新型解决其技术问题所采用的技术方案是:一种简单节约型铅笔套管,为空心管横截面为圆形或正六边形,所述铅笔套管长5-10cm,所述铅笔套管直径等同于铅笔杆的直径。 
本实用新型的有益效果是:可以将不方便写字的短铅笔头利用起来,两个铅笔头又形成了一支新铅笔,简单易操作,从小养成节约的好习惯。 
附图说明
下面结合附图和实施例对本实用新型进一步说明。 
图1是本实用新型的设计原理图。 
图2是本实用新型的新组合的铅笔示意图。 
图中  1.铅笔头 ,2.铅笔套管,3.铅笔头 ,4.新组合的铅笔。 
具体实施方式
如图1所示,所述简单节约型铅笔套管2,为空心管横截面为圆形或正六边形,所述铅笔套管2长5-10cm,所述铅笔套管2直径等同于铅笔头1、3的杆的直径。 
先将铅笔头1套进铅笔套管2中,若觉得不够长可将铅笔头3推进套管中,最终形成新组合的铅笔4的样子,如图2所示。一个铅笔头用完,将另一个铅笔头从后往前推进,继续利用。
