Description

双笔芯圆珠笔
技术领域
本实用新型涉及一种笔。 
背景技术
目前,圆珠笔大多数是只有一种颜色的,要用不同颜色的笔进行记录时需要换笔使用,那样会浪费一定的时间,给书写带来不便;即使有了一些多色笔,但是只有一个笔芯立刻可以使用,换另一种颜色的笔芯使用时需要进行摁压,也给书写带来了一定的麻烦。 
发明内容
为了克服已有圆珠笔的只有一个笔芯、使用不方便的不足,本实用新型提供了一种兼有两个笔芯、使用方便的双笔芯圆珠笔。 
本实用新型解决其技术问题所采用的技术方案是: 
一种双笔芯圆珠笔,包括笔壳,所述笔壳包括上笔壳和下笔壳,上笔壳呈空心的半球形,所述上笔壳的内部顶部设有卡住笔芯尾部的卡口,上笔壳与下笔壳固定连接,所述下笔壳设有用于使用者手握的细腰段,所述下笔壳的底部设有两个供不同笔芯插入的卡孔,两个卡孔的轴线之间的夹角为锐角,所述下笔壳的底部安装笔帽,笔芯的笔头穿过所述卡孔,笔芯的尾部弯曲成圆弧,所述笔芯的尾部卡在卡口上。 
本实用新型的有益效果主要表现在:兼有两个笔芯、使用方便。 
附图说明
图1是双笔芯圆珠笔的示意图。 
图2是放了一支笔芯的示意图。 
图3是放了两支笔芯的示意图。 
图4是笔芯的示意图。 
具体实施方式
下面结合附图对本实用新型作进一步描述。 
参照图1~图4,一种双笔芯圆珠笔,包括笔壳,所述笔壳包括上笔壳1和下笔壳2,上笔壳1呈空心的半球形,所述上笔壳1的内部顶部设有卡住笔芯尾部的卡口3,上笔壳1与下笔壳2固定连接,所述下笔壳2设有用于使用者手握的细腰段,所述下笔壳2的底部设有两个供不同笔芯插入的卡孔6,两个卡孔6的轴线之间的夹角为锐角,所述下笔壳2的底部安装笔帽4,笔芯5的笔头穿过所述卡孔,笔芯5的尾部弯曲成圆弧,所述笔芯的尾部卡在卡口上。 
笔壳用塑料或合金制成;笔壳的外表面为光滑或磨砂表面;笔芯的尾部弯曲成有一定弧度的弧;笔帽用塑料制成。 
本实施例中,先将上笔壳旋开;接着把笔芯装进下笔壳的卡孔里,旋紧上笔壳;然后将笔帽摘掉;最后用手握住笔壳,可以使笔肚在手心处,便可方便地书写;要转换笔芯书写时,只需将笔转换一个角度即可使用另一支笔芯。
