Abstract
A slanted-jaw spanner comprises a spanner body (1). A first fixed claw and a first claw are arranged at a front end of the spanner body (6). A length of the first claw is less than that of the first claw. An inner surface of the first claw is referred to as a first griping surface (31), and is a flat surface. A tooth-shaped gripping head (2) is arranged at a front end of the first fixed claw (6). A plurality of second griping surfaces (21) are arranged at an inner surface of the tooth-shaped gripping head (2). A third griping surface (22) is configured to be adjacent to the second griping surfaces (21), and parallel to the first griping surface (31). The third griping surface and the second griping surface are arranged at a certain angle. In comparison to a conventional spanner, when in use, contact surface areas of a nut and the spanner are increased significantly, thereby effectively reducing forces applied to the gripping surfaces of the nut and the spanner, ensuring the griping surface of the spanner and the outer surface of the nut not being easily deformed, and effectively protecting the spanner and the nut.
Description
本发明涉及一种工具，具体是一种豁口扳手。The invention relates to a tool, in particular to a hook wrench.
扳手是一种常用的安装与拆卸工具。利用杠杆原理拧转螺栓、螺钉、螺母和其他螺纹紧持螺栓或螺母的开口或套孔固件的手工工具。扳手通常在柄部的一端或两端制有夹持螺栓或螺母的开口或套孔，使用时沿螺纹旋转方向在柄部施加外力，就能拧转螺栓或螺母。A wrench is a common mounting and removal tool. Use the principle of leverage to twist bolts, screws, nuts, and other hand tools that hold the opening or socket firmware of the bolt or nut. The wrench usually has an opening or a sleeve hole for clamping a bolt or a nut at one or both ends of the shank, and an external force is applied to the shank in the direction of the rotation of the thread during use, so that the bolt or the nut can be screwed.
现在普通的扳手在松螺母时，由于偏位原因，固定爪和活动爪两夹持边对螺母的施力点在六角螺母对角的两条边上，此时，螺母与扳手的受力面积很小，产生的压强会很大，所以很容易损伤螺母的角边和扳手的夹持面。Nowadays, when the ordinary wrench is loosened, due to the misalignment, the clamping force of the clamping claw and the movable claw on the nut is on the opposite sides of the hex nut. At this time, the force area of the nut and the wrench is very large. Small, the pressure generated will be very large, so it is easy to damage the corner of the nut and the clamping surface of the wrench.
