Description

多用扳手
本实用新型提供一种用于多种形状连接零件的活动扳手。
目前常用的扳手工具是呆扳手、活扳手及管子钳等。呆扳手只能用于单一尺寸的零件。活扳手适用于六角形及方形零件。管子钳只适用于管件。台湾专利NO06147、NO6636虽然可用于六角形及圆形零件,但夹紧圆形零件时容易打滑,且易造成被夹紧零件表面的损伤。因此这些工具在使用时都有一定的局限性。
本实用新型的目的,是提供一种多用扳手,它适用于六角形、圆形等多种连接零件,尤其是在施工现场应用时,可实现一种工具多种用途。
本实用新型的目的是这样实现的,它由扳钩手柄及销轴组成。扳钩具有一定的几何形状及尺寸,两个夹紧面成60°角,且面上开有梯形、矩形、锯齿形、三角形或圆形的牙。手柄顶端有一平直夹紧面,面上开有梯形、矩形、锯齿形、三角形或圆形的牙,在夹紧零件时与扳钩夹紧面成60°角,这样就保证对六角形零件的夹持均为面接触,对圆形零件的夹持用牙咬住,防止其滑动。为了适应不同尺寸的零件,扳钩或手柄上的轴孔开成长圆形或葫芦形,移动扳钩或手柄在销轴上的位置,即可调节扳手的开口间隙尺寸。对于长圆形轴孔,销轴截面为圆形,对葫芦形轴孔,销轴截面为长圆形。销轴采用铆接或活连接,对长圆形截面的销轴,其端面开有螺丝刀槽,以便移动手柄位置时,旋转其长圆截面的方向。
下面结合附图说明本实用新型提出的具体结构细节及工作情况。
附图为多用扳手工作图,由扳钩1销轴2手柄3组成。夹持零件时,首先根据零件尺寸大小调节手柄在销轴上的位置,扳动手柄即可夹紧
