Description

改进的中性笔
技术领域
本实用新型涉及一种书写工具,具体说是一种改进的中性笔。
背景技术
中性笔使用方便,很受学生和白领人士的喜爱。为了适应不同人群的需要,中性笔的笔芯有各种不同的长度。通常一种中性笔只能使用规定长度的笔芯。太长的笔芯装不进去,太短的笔芯装进去无法使用。
发明内容
本实用新型的目的是提供一种适合多种不同长度笔芯的改进的中性笔。
为实现上述目的,本实用新型采用以下技术方案:
本实用新型所述的改进的中性笔包括管状的笔杆、安装在笔杆内的笔芯,笔杆的前端带有圆锥状的笔尖,其特征在于:笔杆的后端带有内螺纹,并通过螺纹连接有堵头,所述堵头为带有外螺纹的圆柱体。
采用上述技术方案后,改进的中性笔能够适合多种不同长度笔芯,避免了买错笔芯带来的尴尬。
附图说明
附图为本实用新型一个实施例的结构示意图。
具体实施方式
下面结合附图和具体实施方式对本实用新型作进一步的描述。
本实用新型所述的改进的中性笔包括管状的笔杆1、安装在笔杆1内的笔芯2,笔杆1的前端带有圆锥状的笔尖4。笔杆1的后端带有内螺纹,并通过螺纹连接有堵头3,所述堵头3为带有外螺纹的圆柱体。笔杆1与堵头3连接部分的螺纹比较长。这样,当笔芯2较长的时候,只要将堵头3稍微旋进笔杆1一点,给笔芯2留出较大的空间就可以将笔芯2安装进去;如果笔芯2比较短,则可以将堵头3多旋进一点,使笔芯2的前端能够露出笔尖即可。
当然,还可以根据笔芯2的长度,设计不同长度的堵头3,一种长度的笔芯2对应使用一种堵头3。
