Description

椭圆规
技术领域
本实用新型涉及一种圆规,尤其是一种椭圆规。
背景技术
目前使用的圆规只能画圆,画椭圆时需借助辅助直尺,且需很多步骤才能画成,很不方便。
发明内容
本实用新型的目的就是要提供一种画椭圆步骤简单、方便的椭圆规。
本实用新型的目的是这样实现的:一种椭圆规,包括:支架和手柄,支架通过转轴与手柄连接,转轴上设有定支架,定支架底端设有铅笔,铅笔与定支架之间设有定滑轮,定滑轮上设有线槽,支架底端设有锥针,锥针上设有针孔,支架中端设有旋钮,旋钮上设有细绳,细绳与针孔连接。
本实用新型由于采用上述结构,实现了画椭圆一步成形,步骤简单、方便的目的
附图说明
下面结合附图和具体实施方式作进一步说明。
图1是本实用新型的结构示意图。
具体实施方式
本实用新型的结构包括:一种椭圆规,包括:支架1和手柄2,支架1通过转轴3与手柄2连接,转轴3上设有定支架4,定支架4底端设有铅笔5,铅笔5与定支架4之间设有定滑轮6,定滑轮6上设有线槽7,支架1底端设有锥针8,锥针8上设有针孔,支架1中端设有旋钮9,旋钮9上设有细绳10,细绳10与针孔连接。
作椭圆时调节旋钮9将细绳10的长度调节为所画椭圆大小的长度,固定好锥针8将细绳10嵌入线槽7中,利用定滑轮6,转其中一个支架1,便可画出所需椭圆。
