Abstract

一种退螺丝钻头,涉及退螺丝工具技术领域,包括圆柱形主体,在所述圆柱形主体上设置有螺丝退出端,所述螺丝退出端是锥形结构,在其锥面上设置有螺旋牙,圆柱形主体和螺丝退出端之间设置有凹槽,该退螺丝钻头可以有将被破坏了的螺栓、螺钉退出,使用方便。

Description

退螺丝钻头
技术领域
本实用新型涉及一种退螺丝工具,特别是将断头螺丝或头部槽形被破坏的螺丝从相应的构件上退出的工具。
背景技术
螺栓、螺钉作为紧固件在构件连接上的应用十分广泛。然而,在安装连接或拆卸构件的过程中,螺栓、螺钉会受某些原因的影响而断头,螺钉头部的槽形也会受到破坏,上述情形发生后,无法用螺丝刀将被破坏了的螺栓、螺钉退出,影响连接。
发明内容
为了克服现有技术的不足,本实用新型提供一种退螺丝钻头,该退螺丝钻头可以有将被破坏了的螺栓、螺钉退出,使用方便。
本实用新型的技术方案是:一种退螺丝钻头,包括圆柱形主体,在所述圆柱形主体上设置有螺丝退出端,所述螺丝退出端是锥形结构,在其锥面上设置有螺旋牙,圆柱形主体和螺丝退出端之间设置有凹槽。
由于该退螺丝钻头包括圆柱形主体,在所述圆柱形主体上设置有螺丝退出端,所述螺丝退出端是锥形结构,在其锥面上设置有螺旋牙,圆柱形主体和螺丝退出端之间设置有凹槽,因此,该退螺丝钻头可以有将被破坏了的螺栓、螺钉退出,使用方便。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步说明。
图1是本实用新型退螺丝钻头的结构图。
具体实施方式
如图1所示,一种退螺丝钻头,包括圆柱形主体1,在所述圆柱形主体1上设置有螺丝退出端2,所述螺丝退出端2是锥形结构,在其锥面上设置有螺旋牙,圆柱形主体1和螺丝退出端2之间设置有凹槽3。发生螺丝断头时,先用电钻在螺栓、螺钉的断头部位或螺钉头部的槽形部沿轴向打孔,再将螺丝退出端2置入孔内,旋转该工具,螺丝退出端2即钻进前述孔内,与螺栓或螺钉咬合在一起,进而将它们取出,使用方便。

Claims (1)
