Description

双型号铅笔
技术领域
本实用新型涉及书写工具,具体为一种双型号铅笔。
背景技术
现有铅笔的结构包括笔杆和设于笔杆内的单一型号(如2B、HB、6H等)的铅笔芯。手工绘制机械图时,绘图人员需要使用不同型号的铅笔画粗细不同的线条,但是每种铅笔只对应一种型号,使得制图人员每次绘图的时候得准备一大把不同型号的铅笔,需要某种型号的铅笔找某种型号,不仅找起来麻烦、绘图不便,而且不方便携带。
发明内容
本实用新型为了解决现有铅笔只有单一型号铅笔芯给制图人员带来的绘图不便,不易携带的问题,提供一种双型号铅笔。
本实用新型是采用如下技术方案实现的:双型号铅笔,包括笔杆,设于笔杆内的铅笔芯,铅笔芯是由两段不同型号的铅芯组成。双型号铅笔两端对应不同型号的铅芯,这样绘制图纸的时候,调转笔端就可以转换不同的型号,不仅绘图方便,而且携带起来可以少带一半的铅笔。
本实用新型所述的双型号铅笔由于一支铅笔对应两种不同型号的铅芯,绘图方便,便于携带,设计巧妙,实用方便。
附图说明
图1为本实用新型所述的双型号铅笔的内部结构示意图;
图中:1-笔杆,2-铅芯,3-铅芯。
具体实施方式
双型号铅笔,包括笔杆1,设于笔杆1内的铅笔芯,铅笔芯是由两段不同型号的铅芯2、3组成。双型号铅笔的制作工艺与现有铅笔的相同,笔杆1采用普通铅笔的笔杆,铅笔芯采用两段不同型号的铅芯2、3,这样制的铅笔具有两种不同型号。
