Abstract

一种笔芯,包括笔芯杆(1)和笔芯头(2),笔芯杆(1)成螺旋状。笔芯杆(1)绕着中心轴(3)依次往下旋转。本实用新型笔芯因为采取的是螺旋式结构,所以该笔芯杆里的油墨要比普通笔芯杆里的至少多一倍,增大了油墨的使用量,解决了在使用过程中油墨不足和造成材料浪费的问题。

Description

笔芯
技术领域
本实用新型涉及一种文具用品,具体讲是一种供人书写的笔芯。 
背景技术
目前,传统的笔芯基本是直线型杆体。在大量书写的情况下,笔芯中的油墨由于容量有限,很快的就被写完了,从而导致了人手中有一大堆的有杆而无笔芯的现象,不仅给工作学习到来了不便,而且造成了材料的极大浪费。 
发明内容
本实用新型的目的是克服现有技术中的不足,提供了一种有效的增加了笔芯油墨容量的珠笔芯。 
为解决上述技术问题,本实用新型提供的笔芯包括笔芯杆和笔芯头,所述的笔芯杆成螺旋状。 
采用以上结构后,本实用新型与现有技术相比,具有以下优点:本实用新型笔芯因为采取的是螺旋式结构,所以该笔芯杆里的油墨要比普通笔芯杆里的至少多一倍,增大了油墨的使用量,解决了在使用过程中油墨不足和造成材料浪费的问题。 
作为改进,所述的笔芯杆绕着中心轴依次往下旋转。此结构使得笔芯看上去更加的美观。 
附图说明
附图是本实用新型笔芯的整体结构示意图。 
其中:1、笔芯杆;2、笔芯头;3、中心轴。 
具体实施方式
如附图所示,一种笔芯,包括笔芯杆1和笔芯头2,所述的笔芯杆1成螺旋状。 
所述的笔芯杆1绕着中心轴3依次往下旋转。 

Claims (2)

1.一种笔芯,包括笔芯杆(1)和笔芯头(2),其特征在于:所述的笔芯杆(1)成螺旋状。
2.根据权利要求1所述的笔芯,其特征在于:所述的笔芯杆(1)绕着中心轴(3)依次往下旋转。
