Abstract

本实用新型公开了一种双螺旋形笔芯，包括两根螺旋形的墨水塑料管（1），所述的两根墨水塑料管（1）采用双螺旋方式构成一体，所述的墨水塑料管（1）端部一头设有金属笔尖（2）。该墨水塑料管采用螺旋形状，两根墨水塑料管采用双螺旋方式构成一体，形如麻花，可以储存更多的墨水，延长了笔芯的使用寿命，减少了浪费；同时，双螺旋的结构组成使得笔芯较常规的笔芯要粗，能适用于直接握住笔芯书写。

Description

双螺旋形笔芯
技术领域
本实用新型涉及文具用品，尤其涉及双螺旋形笔芯。
背景技术
目前，书写用的圆珠笔和中性笔为笔芯和笔套结构，笔芯为带有墨水或者油墨的管状物，前端有金属笔尖。传统的笔芯储存的墨水少，当笔芯内墨水耗尽时，笔尖往往还可以继续使用，遗弃整支笔芯造成了一种浪费。
发明内容
本实用新型所要解决的技术问题是：提供一种可以延长笔芯的使用寿命，减少浪费的双螺旋形笔芯。
本实用新型解决上述问题所应采用的技术方案为：一种双螺旋形笔芯，包括两根螺旋形的墨水塑料管，所述的两根墨水塑料管采用双螺旋方式构成一体，所述的墨水塑料管端部一头设有金属笔尖。
与现有技术相比，本实用新型的优点在于：该墨水塑料管采用螺旋形状，两根墨水塑料管采用双螺旋方式构成一体，形如麻花，可以储存更多的墨水，延长了笔芯的使用寿命，减少了浪费；同时，双螺旋的结构组成使得笔芯较常规的笔芯要粗，能适用于直接握住笔芯书写。
附图说明
图1是本实用新型双螺旋形笔芯的结构示意图。
在图1中：1、墨水塑料管，2、笔尖。
具体实施方式
下面结合附图对本实用新型的实施例作进一步描述。
如图1所示，一种双螺旋形笔芯，包括两根螺旋形的墨水塑料管（1），所述的两根墨水塑料管（1）采用双螺旋方式构成一体，所述的墨水塑料管（1）端部一头设有金属笔尖（2）。
