Description

一种节约型铅笔
所属技术领域
本实用新型涉及一种铅笔,特别是一种节约型铅笔。
背景技术
铅笔是日常生活学习中必不可少的用品,但是由于存在一个手握端,无论铅笔如何使用,都会有一段铅笔无法使用,具体大约在整体长度的30%-35%左右。
发明内容
本实用新型的目的是针对现有技术不能克服对铅笔的浪费,提供一种节约型铅笔。
为实现以上目的,本实用新型通过以下技术方案实现:
节约型铅笔,包括一端带有螺纹的铅笔和一个带有螺纹的塑料套子,其特征在于:该种铅笔比普通铅笔略短,约为15cm左右,铅笔上的螺纹约为1cm,塑料套子长度约为6cm左右,塑料套子可以与铅笔良好联接。
本实用新型的优点是:大部分人使用铅笔的有效长度为铅笔总长度的65%-70%,而该种实用新型基本可以全部使用完,因此,节约了大量的铅笔芯和木材。例如,我国每年的铅笔生产量超过十亿支,如果一支铅笔可节约成本0.05元,按十亿支计算,可节约成本5000万元。
附图说明
图1是本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型的具体实施方式进行详细说明。
参看图片1,该种节约型铅笔,包括铅笔1和塑料套子2,铅笔和塑料套子可以通过螺纹联接起来,当铅笔使用到一定长度,不能正常使用时,可装上塑料套子,将塑料套子作为手握端继续使用,这样可使铅笔的利用率大大提高,塑料套子可重复使用。
