Description

多功能教学测量尺
技术领域:本实用新型属于数学教学用具技术领域,具体地讲是一种多功能教学测量尺。
背景技术:目前,在数学教学过程中需要很多测量尺,如直尺、三角尺、量角尺、十字座标尺等,这些教具大都单一存在,使用起来逐一拿取应用,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操作简便、省时省力,且便于携带的多功能教学测量尺。
本实用新型的技术方案是:包括半圆量角尺,其特征是在半圆量角尺右侧设有直尺,直尺中段设有转轴,转轴上设有两条短尺。
本实用新型的有益效果是:本实用新型结构简单,在数学教学过程中操作简便、省时省力,且便于携带,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、半圆量角尺,2、直尺,3、转轴,4、短尺。
具体实施方式:包括半圆量角尺1,其特征是在半圆量角尺1右侧设有直尺2,直尺2中段设有转轴3,转轴3上设有两条短尺4。在数学教学过程中,半圆量角尺1量角,短尺4作三角并可以借助直尺2作十字坐标尺。
