发明内容    本实用新型的目的是提供一种防扎伤圆规,用于解决普通圆规在使用时容易造成扎伤事故的问题。
为达到上述目的,本实用新型防扎伤圆规,包括支撑杆、旋转杆、连接架和指针,在指针的针头处设有橡胶帽。
采用上述结构后,使用者在准备画圆时拔出指针的橡胶帽,用指针作为支撑点,然后转动旋转杆即可进行绘画;在用过圆规之后,使用者把橡胶帽插在指针上,避免扎伤人。
本实用新型的优点是:结构简单、方便实用、安全耐用,可通过橡胶帽的保护作用,避免扎伤事故的发生。
附图说明    图1为本实用新型防扎伤圆规的整体结构示意图。
具体实施方式    如图1所示,本实用新型防扎伤圆规,包括支撑杆1、旋转杆2、连接架3和指针4,在指针4的针头处设有橡胶帽5。其中,橡胶帽5的直径略大于指针4直径,长度为1厘米。当使用者画圆时,拔出橡胶帽5用指针4支撑即可绘画;在用过之后,使用者把橡胶帽5套在指针4上,这样在移动的时候就不必担心扎伤皮肤了。
