Abstract

防断油中性笔涉及一种文具。防断油中性笔是在中性笔芯的芯杆外设置上、下两个泡沫塑料圈,此泡沫塑料圈的外径应略小于中性笔杆的内径。采用防断油中性笔的有益效果是插有泡沫塑料圈保护的中性笔芯的中性笔杆,在跌地时可以防震,使用时就不会断油。

Description

防断油中性笔
技术领域:
本实用新型涉及一种文具。
背景技术:
现有的中性笔的笔芯在插入笔杆中时,笔芯与笔杆尚有相当大的间隙。所以在使用时,一不小心跌在地上,跌过的中性笔因为受到震动,使笔芯中的空气与油混和,于是再书写时会断油,使书写不流畅。
发明内容:
本实用新型的目的是要提供一种防断油中性笔。防断油中性笔是在中性笔芯的芯杆外设置上、下两个泡沫塑料圈,此泡沫塑料圈的外径应略小于中性笔杆的内径。插有泡沫塑料圈保护的中性笔芯的中性笔杆在跌地时可以防震,使用时就不会断油。
防断油中性笔是在中性笔芯的芯杆外设置上、下两个泡沫塑料圈,此泡沫塑料圈的外径应略小于中性笔杆的内径。
采用防断油中性笔的有益效果是插有泡沫塑料圈保护的中性笔芯的中性笔杆,在跌地时可以防震,使用时就不会断油。
附图说明:
图1是防断油中性笔的结构示意图。
具体实施方式:
参照图1,防断油中性笔是在中性笔芯的芯杆1外设置上、下两个泡沫塑料圈2,泡沫塑料圈2的外径应略小于中性笔笔杆的内径。
