Abstract

本实用新型公开了一种圆珠笔,包括笔杆、直条形笔芯、螺旋形笔芯;笔杆两端均设有一个笔头,其中直条形笔芯设在其中一个笔头内,螺旋形笔芯设在另一笔头内。本实用新型可解决如何使在一根笔芯用完后,还可让笔继续工作的问题。

Description

圆珠笔技术领域[0001 ] 本实用新型涉及一种圆珠笔。 背景技术[0002] 目前的笔大都是采用一根笔芯,在笔芯用完后就需要更换另外一根笔芯,由于有时会忘记携带笔芯,这时就无法使用笔,这给使用带来了诸多不便。实用新型内容[0003] 本实用新型的目的是提供一种圆珠笔,解决如何使在一根笔芯用完后,还可让笔继续工作的问题。[0004] 圆珠笔,包括笔杆、直条形笔芯、螺旋形笔芯;笔杆两端均设有一个笔头,其中直条形笔芯设在其中一个笔头内,螺旋形笔芯设在另一笔头内。[0005] 本实用新型的有益效果是,由于笔杆两端均有笔芯,且其中一根笔芯是采用螺旋状结构,这样在不改变笔杆长度的情况下,一个笔杆同时可安装两根笔芯,当一根笔芯无法工作时,可使用另一根笔芯,从而给使用者带来便利。附图说明[0006] 图1是具体实施方式的结构示意图;[0007] 图2直条形笔芯的结构示意图;[0008] 图3螺旋状笔芯的结构示意图;[0009] 图中1.笔杆、2.直条形笔芯、3.笔头、4.螺旋状笔芯。 具体实施方式[0010] 请参考图1至图3,实施例的产品包括一根笔杆1,两根笔芯;其中一个为直条形笔芯2,另一个为螺旋状笔芯4 ;笔杆1两端设有笔头3,两根笔芯分别对应的设置在笔头3 内,由于其中一根笔芯是螺旋状的,这样直条形的笔芯大部分都插入到螺旋状笔芯4的中心内,这使得在不改变笔杆1长度却可安装两根笔芯变成可能。
