Abstract

本发明提供一种设置间距滑轨的圆规,所述圆规在两支规杆之间连接有可宽窄调节的间距滑轨,该间距滑轨一端通过铰轴与一支规杆连接固定,另一端套在另一规杆的调节固定螺栓上。使用圆规时,可通过间距滑轨调节并固定两支规杆之间的隔距,由此可让调好的圆规能固定使用。

Description

设置间距滑轨的圆规
技术领域
本发明涉及一种圆规,具体的说是一种设置间距滑轨的圆规。
背景技术
传统的圆规都是直接调节两支规杆的间距确定距离画圆形图的,由于两支规杆不能固定,使用圆规过程中,很容易出现失误。
发明内容
本发明提供一种设置间距滑轨的圆规,可很方便的将调好间距的两支规杆固定使用。
本发明包括圆规的两支规杆,所采用的技术方案在于:所述圆规在两支规杆之间连接有可宽窄调节的间距滑轨,该间距滑轨一端通过铰轴与一支规杆连接固定,另一端套在另一规杆的调节固定螺栓上。
本发明的有益效果在于:通过采用上述技术方案,使用圆规时,可通过间距滑轨将调节好间距的两支规杆固定不变,由此画圆图形时不会出现失误,有利圆规实际使用时更加精确。
附图说明
下面结合附图和实施例对本发明作进一步详述。
图1为本发明的结构示意图。
具体实施方式
图1所示:圆规在两支规杆1之间连接有可宽窄调节的间距滑轨2,该间距滑轨2一端通过铰轴3与一支规杆1连接固定,另一端套在另一规杆1的调节固定螺栓4上。
