Abstract

本实用新型是一种铅笔。包括铅笔外层和铅芯,其特征在于铅芯的长度短于铅笔外层的长度。铅芯短出的部分用其它辅料填充或使其空心。本实用新型的铅笔由于不需用与铅笔外层一样长的铅芯,能节药铅芯原材料,降低铅笔生产成本。

Description

一种能节省铅芯的铅笔
技术领域
本实用新型涉及文具用品,具体地说是一种能节省铅芯的铅笔。
现有的铅笔,无论铅笔外层是木质还是纸质,其铅芯都是与铅笔外层一样长。而实际当中,铅笔用到还剩40%左右长度时,就几乎不能使用了,因为根本就不能捏住铅笔。用整根铅芯就浪费了部份铅芯材料。
发明内容
本实用新型的目的是提供一种能节省铅芯材料的铅笔。
本实用新型是这样实现的:在包括铅笔外层和铅芯其础上,使铅芯比铅笔外层短一部份。铅芯短的部份用其它辅料填充或空心。
本实用新型的铅笔由于不需用与铅笔外层一样长的铅芯,能节药铅芯原材料,降低铅笔生产成本。
附图说明
图1为本实用新型的结构示意图。
其中,1-铅芯,2-铅笔外层,3-辅料或空心。
如图所示,本实用新型的铅笔是在现有铅笔结构的基础上,即包括铅笔外层和铅芯,将铅芯的长度制成短于铅笔外层的长度。铅芯短的部份3用其它辅料(如塑料等)填充或使其空心。
本实用新型适用于铅笔外层为木质、纸质等、铅芯为各种类型的铅笔。
