Description

一种圆珠笔芯
技术领域
本实用新型涉及一种学习用具,具体地说是一种圆珠笔芯。
背景技术
目前,圆珠笔芯被广泛使用,但笔芯管一般为很细的圆柱体,这就使得笔芯内只能存储少量的油墨,影响笔芯的使用时间,另外现有圆珠笔芯单独使用很不方便。
实用新型内容
本实用新型的目的在于提供一种圆珠笔芯,该笔芯结构简单,可以存储更多油墨,而且可以单独使用。
本实用新型解决其技术问题所采取的技术方案是:一种圆珠笔芯,包括笔头和笔芯杆,其特征是所述的笔芯杆中间部分为螺旋状。
本实用新型的有益效果是:由于笔芯杆中间部分为螺旋状,该种笔芯结构油墨存储量大,可以使笔芯的使用时间更长;而且中间直径较大,可以单独使用笔芯。
附图说明
图1为本实用新型的结构示意图。
图中:1笔芯杆,2笔头。
具体实施方式
如图1所示。一种圆珠笔芯,它包括笔芯杆1和笔尖2,笔芯杆1中间部分为螺旋状,两端为细圆柱,笔尖2固定在笔芯杆1一端。由于笔芯杆中间部分为螺旋状,油墨存储量大,可以使笔芯的使用时间更长。而且中间直径较大,可以单独使用笔芯。
