Abstract

一种能够画出圆弧的笔,包括笔杆,在笔杆下端开设有螺纹孔,在螺纹孔内螺纹连接有一根螺杆,在螺纹远离笔杆的一端螺纹连接有定位块,在定位块的下端固定有插针。使用时,可以将螺杆分别与笔杆和定位块连接,在将插针插入到纸中,这样就可以绘制出圆弧了,由于螺杆、定位块和笔杆都是可以分解的,因此体积可以变小,便于人们携带。

Description

一种能够画出圆弧的笔
技术领域
本发明涉及一种能够画出圆弧的笔。
背景技术
在人们工作学习时,常常需要使用到圆规,而圆规体积较大,不便于人们携带。
发明内容
本发明要解决的技术问题是提供一种能够画出圆弧的笔,可以分解,体积小,便于携带。
为了解决上述技术问题,本发明的技术方案为:一种能够画出圆弧的笔,包括笔杆,在笔杆下端开设有螺纹孔,在螺纹孔内螺纹连接有一根螺杆,在螺纹远离笔杆的一端螺纹连接有定位块,在定位块的下端固定有插针。
本发明的有益效果为:使用时,可以将螺杆分别与笔杆和定位块连接,在将插针插入到纸中,这样就可以绘制出圆弧了,由于螺杆、定位块和笔杆都是可以分解的,因此体积可以变小,便于人们携带。
附图说明
下面结合附图对本发明做进一步的说明:
图1为本发明主视的结构示意图。
具体实施方式
一种能够画出圆弧的笔,包括笔杆1,在笔杆1下端开设有螺纹孔,在螺纹孔内螺纹连接有一根螺杆3,在螺杆3远离笔杆1的一端螺纹连接有定位块2,在定位块2的下端固定有插针21。
使用时,可以将螺杆3分别与笔杆1和定位块2连接,在将插针21插入到纸中,这样就可以绘制出圆弧了,由于螺杆3、定位块2和笔杆1都是可以分解的,因此体积可以变小,便于人们携带。
