Description

画圆直尺
技术领域
本发明涉及直尺的技术领域,尤其涉及能多画圆性的直尺。
背景技术
目前市场上的直尺只能画直线,当需要画圆时,还得需要圆规才能画圆,有时遇到没有圆规时,给使用者带来一定的麻烦。
发明内容
为了克服上述现有技术的不足,本发明提供了画圆直尺,可定距离画直线和圆的直尺。
本发明所采用的技术方案是:画圆直尺,由左滑条、尺身和右滑条组成,其特点在于:左滑条和右滑条镶嵌在尺身上,左滑条和右滑条可在尺身上左右滑动。
所述:左滑条和右滑条,中间位置有个定点的洞,方便画圆。
所述:尺身,中间位置设计成空心和一侧有刻度,方便左滑条和右滑条(3)用来画直线。
本发明的有益效果是:画圆直尺,可定距离画直线和圆的直尺。
附图说明
图1为本发明的结构示意图。
图1,左滑条(1)、尺身(2)和右滑条(3)。
具体实施方式
下面结合附图和实施例对本发明进一步的说明。
如图1所示,画圆直尺,由左滑条(1)、尺身(2)和右滑条(3)组成。当需要画圆时,左滑条(1)中间位置有个定点的洞作为固定圆心位置,右滑条(3)中间位置有个定点的洞通过在尺身(2)左右滑动来定圆的半径,右滑条(3)中间位置有个定点的洞绕圆周运动即可画出圆;当需要画定距离画直线时,只需定好左滑条(1)中间位置有个定点的洞,右滑条(3)中间位置有个定点的洞在尺身(2)看刻度左右画直线。
