Description

续铅型圆规
技术领域:本实用新型是属圆规,具体涉及一种续铅型圆规。
背景技术:目前市面上的圆规在用完了另一侧的铅芯后,要把螺旋钮拧下来再往里面放铅芯,铅芯的长短也是受限制的,更换起来比较麻烦,不省时也不省力,也常会弄的满手是铅笔末。
发明内容:本实用新型的目的在于提供一种方便使用的续铅型圆规,改变传统圆规更换铅芯麻烦的缺点,长时间不用更换铅芯,更换起来也更加简单易行,方便快捷。
本实用新型是这样实现的:一种续铅型圆规,它主要是由转杆、转轴、衔接杆、尖头、螺旋钮和续铅型铅笔组成,其特征在于:由衔接杆连接续铅型铅笔,续铅型铅笔由铅笔笔杆、续铅腔、斜道和笔芯通道组成,另一侧是由螺旋钮和尖头组成。
由于采用上述技术方案,使用时,将铅芯放入续铅腔内,因为续铅腔内空间较大,可以一次放入多根铅芯,铅芯进入后会顺着斜道进入到铅芯通道内,具有长时间不用更换铅芯,更换起来也更加简单易行,方便快捷的优点。
附图说明:以下结合附图和具体实施例来对本实用新型的技术方案做详细说明。附图是本实用新型的结构示意图。
具体实施方式:参考附图,一种续铅型圆规,它主要是由转杆9、转轴8、衔接杆1、尖头7、螺旋钮6和续铅型铅笔组成,由衔接杆1连接续铅型铅笔,续铅型铅笔由铅笔笔杆2、续铅腔3、斜道4和笔芯通道5组成,另一侧是由螺旋钮6和尖头7组成即可。
