Abstract

环保型自动铅笔，本实用新型的特征在于紧固笔芯的3.5cm的铜制套管顶端至中间0.8cm处为园锥形，从0.8cm处至末端3.5cm处同样为圆锥形，套管顶端至中间长2.2cm处为切口。

Description

环保型自动铅笔
技术领域
该实用新型涉及一种环保型自动铅笔的制作工艺
背景技术
现阶段市场上大多流行自动、木制两种结构的铅笔，自动铅笔芯直径为0.5-0.7mm，因笔芯细小，填充笔芯时容易折断且书写时更容易断芯；木制铅笔耗费森林资源，污染环境，且使用时要削，削的过程中很容易折断四分之一的笔头又要丢掉，耗时耗力浪费大，这两种结构的铅笔极不适应小学、一二年级学龄前儿童使用，由此，找出一种适合以上年龄阶段儿童使用的铅笔尤为重要.
发明内容
该实用新型的目的根据以上所述，制作一种适合小学一、二年级及学龄前儿童使用的铅笔。
本实用新型的实施方式：铅笔外壳以塑料的圆珠笔外壳为基础，将笔芯加以改进：
具有强度的笔芯长为16cm，直径为1.5mm；
环保型自动铅笔其特征在于紧固笔芯的3.5cm处的铜制套筒顶端至中间0.8cm处为圆锥形，从0.8cm处至未端3.5cm处同样为圆锥形，套管顶端至中间长2.2cm处为切口.
其特征在于笔身顶端长2.6cm处为铜套管.
附图说明
图1是内紧固件，图2是外紧固件，图3是效果图.
具体实施方式
该笔的优点是：制作简便，方便好使，既有普通自动铅笔的功能，更有普通自动铅笔达不到的效果，完全可以代替木制铅笔，既不断芯，又不会后退，因笔芯是1.5mm(普通自动铅笔笔芯0.5mm或0.7mm)填充笔芯不容易折断，非常适合少儿使用。
