Abstract

本实用新型涉及一种多功能教学绘图尺的主尺。属于文具领域。该主尺1两侧边分别为长度刻度边2和角度刻度边3,其间夹有圆孔4,其特征是:角度刻度边3为圆弧状量角器。

Description

一种多功能教学绘图尺的主尺
所属领域
本实用新型涉及一种多功能教学绘图尺的主尺,属于文具领域。
背景技术
中国专利申请号为01127578.2的专利申请公开了一种多功能教学绘图尺。该尺在实现量角器的功能时必须主尺和副尺配合才行,使用起来不很方便。
发明内容
本实用新型的目的是提供一种多功能教学绘图尺的主尺。其特征是:该主尺的角度刻度边为一圆弧状的量角器。由于该主尺本身即为量角器,因此它不仅可以和副尺配合实现圆规的功能,而且可以单独度量角,使用更加方便。
附图说明
图1为该实用新型示意图;图2为副尺示意图
具体实施方式
主尺1两侧边分别为长度刻度边2和圆弧状的角度刻度边3,其间夹有圆孔4。相邻两圆孔间的孔心距相同,且孔心都在长度刻度线的延长线上。使用时该主尺1可单独作量角器使用也可和副尺5配合作圆规或丁字尺使用。

Claims (1)

1、一种多功能教学绘图尺的主尺,由长度刻度边2、角度刻度边3和其间的圆孔4构成,其特征是角度刻度边3为圆弧状量角器。
