Description

尺规两用器
技术领域:本实用新型属于数学教学用具技术领域,具体地讲是一种尺规两用器。
背景技术:目前,在数学教学过程中一般使用直尺进行测量长度,用圆规作圆,圆的直径、半径也往往需要用直尺测量,这样操作起来十分麻烦、费时费力,且不便于携带,给教师增加了工作难度。
发明内容:本实用新型的目的是提供一种在数学教学过程中作圆和测量长度及半径、直径时操作简便、省时省力的尺规两用器。
本实用新型的技术方案是:包括直尺,其特征是在直尺零点上设有定位针,直尺上设有套管,套管中央设有定位螺母,套管前段设有圆环,圆环边缘设有固定夹。
本实用新型的有益效果是:本实用新型结构简单,在数学教学过程中作圆和测量长度及半径、直径时操作简便、省时省力,减轻了教师的工作难度。
附图说明:附图1为本实用新型的结构示意图。
图中1、直尺,2、定位针,3、套管,4、定位螺母,5、圆环,6、固定夹。
具体实施方式:包括直尺1,其特征是在直尺1零点上设有定位针2,直尺1上设有套管3,套管3中央设有定位螺母4,套管3前段设有圆环5,圆环5边缘设有固定夹6。在数学教学过程中,将笔插入圆环5,固定夹6固定笔,按住定位针2,旋转直尺1作圆即可。
