Description

一种可伸缩画角圆规
技术领域
本实用新型涉及一种可伸缩画角圆规。
背景技术
普通的圆规是固定的,不能适应画不同半径的圆的需求。
实用新型内容
本实用新型的目的就是要解决现有技术中,普通的圆规是固定的,不能适应画不同半径的圆的需求的问题,提供一种可伸缩画角圆规。
本实用新型采用的技术方案是:一种可伸缩画角圆规,其特征在于:刻度盘分别与针柱和笔柱相连,针柱分为三段,是可伸缩的,针柱上设置固定旋钮,笔柱分为两端,也是可伸缩的,笔柱上设置固定旋钮。
本实用新型的有益效果是:该圆规可伸缩,可画出不同半径的圆或者扇形,还可以测量角度。
附图说明
下面结合附图和实施例对本实用新型作进一步详细说明。
图为本实用新型的结构示意图。
图中:1、刻度盘,2、针柱,3、固定旋钮,4、笔柱,5、固定旋钮。
具体实施方式
如图,一种可伸缩画角圆规,其特征在于:刻度盘1分别与针柱2和笔柱4相连,针柱2分为三段,是可伸缩的,针柱2上设置固定旋钮3,笔柱4分为两端,也是可伸缩的,笔柱4上设置固定旋钮5
针柱和笔柱都是可伸缩的,调好长度后旋动固定旋钮固定即可,刻度盘可以用来测量角度。
