Abstract

本实用新型公开了一种带卷尺的圆规,包括由铰链连接的左支腿和右支腿,在左支腿底部开有可嵌入卷尺限制片的限制口,卷尺的限制片与限制口固定连接。在圆规腿底部增加一个限制口不会增加很多的成本,用于连接卷尺,画圆时可以直接读出所画圆的半径。

Description

带卷尺的圆规
技术领域
本实用新型涉及一种文具,尤其涉及一种带卷尺的圆规。
背景技术
圆规是绘圆用的绘图工具,目前市面上的圆规在画圆时需要借助于尺子测量出所画圆的半径,使用不便。
实用新型内容
本实用新型的目的就在于提供一种带卷尺的圆规,利用这种圆规可以直接读出所画圆的半径,并且不需要增加太多的成本。
为了实现上述目的,本实用新型采用的技术方案是这样的:带卷尺的圆规,包括由铰链连接的左支腿和右支腿,还包括卷尺,左支腿底部开有可嵌入卷尺限制片的限制口,卷尺的限制片与限制口固定连接。
与现有技术相比,本实用新型的优点在于:在圆规腿底部增加一个限制口不会增加很多的成本,限制口与卷尺的限制片连接,画圆时可以直接读出所画圆的半径。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
下面将结合附图对本实用新型作进一步说明。
实施例:参见图1,本实用新型的带卷尺的圆规包括铰链连接的左支腿1,右支腿2,左支腿1下端固定有笔套并设有一个可嵌入卷尺限制片的限制口3,卷尺4的限制片与限制口3固定连接,圆规腿2下端固定有笔尖,
使用时,将卷尺4拉到所需的半径,用锁紧器5锁紧卷尺4即可画圆。
本实用新型的带卷尺的圆规,在圆规腿1底部增加一个限制口3不会增加很多的成本,限制口3用于连接卷尺4,可以直接读出所画圆的半径。
