Abstract

本实用新型提供一种同心圆圆规,包括圆规的立脚臂和划线臂一,其特征在于:圆规的划线臂一上通过连接桥再设有划线臂二;立脚臂和划线臂一之间设有角度尺一,划线臂一和划线臂二之间设有角度尺二。在使用时利用两个划线臂可以同时画同心圆,实现了统一,角度尺的设置是为了更加方便调整同心圆的尺寸,结构简单使用方便。

Description

同心圆圆规
技术领域
本实用新型涉及一种文具用品,具体是一种同心圆圆规。
背景技术
圆规是常用的画图工具,但是其功能单一,只能画单圆,遇到同心圆时需要调节圆规来实现,多个相同的同心圆时需要多次调整非常麻烦,再者容易出现尺寸不统一的问题。
发明内容
本实用新型为了方便一次画多个同心圆,特提出一种同心圆圆规。
为此本实用新型的技术方案为,同心圆圆规,包括圆规的立脚臂和划线臂一,其特征在于:圆规的划线臂一上通过连接桥再设有划线臂二。
对上述方案的改进在于:立脚臂和划线臂一之间设有角度尺一,划线臂一和划线臂二之间设有角度尺二。
有益效果:
本实用新型在使用时利用两个划线臂可以同时画同心圆,实现了统一,角度尺的设置是为了更加方便调整同心圆的尺寸,结构简单使用方便。
附图说明
图1是本实用新型的结构示意图。
 图中1是立脚臂,2是划线臂一,3是划线臂二,4是角度尺一,5是连接桥,6是角度尺二。
具体实施方式
本实用新型如图1所示。
同心圆圆规,包括圆规的立脚臂1和划线臂一2,圆规的划线臂一2上通过连接桥5再设有划线臂二3。
立脚臂1和划线臂一2之间设有角度尺一4,划线臂一2和划线臂二3之间设有角度尺二6。

Claims (2)

1.同心圆圆规,包括圆规的立脚臂和划线臂一,其特征在于:圆规的划线臂一上通过连接桥再设有划线臂二。
2.根据权利要求1所述的同心圆圆规,其特征在于:立脚臂和划线臂一之间设有角度尺一,划线臂一和划线臂二之间设有角度尺二。
