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:包括捏柄、转轴、定位臂、弧尺和画臂,其特征是在定位臂前段设有折页,折页上设有直尺。
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、捏柄,2、转轴,3、定位臂,4、弧尺,5、画臂,6、折页,7、直尺。
具体实施方式:包括捏柄1、转轴2、定位臂3、弧尺4和画臂5,其特征是在定位臂3前段设有折页6,折页6上设有直尺7。在数学教学过程中作圆和测量长度及半径、直径时,用画臂5和定位臂3作圆,展开折页6,用直尺7进行测量即可。
