Abstract

The invention discloses a structure of tooth-shaped part of a tool. The body of the structure is the tooth-shaped part which is implemented on a torque tool in a matching mode and is provided with a plurality of clamping edges, each clamping edge consists of an oblique edge and an arc-shaped edge, and the intersection angle of the oblique edge and the arc-shaped edge is between 20 and 55 DEG to facilitate the sliding and jumping of the body, reduce the wear of the body during jumping, and maintain service life and normal operation of the body. The structure reduces structural wear greatly and improves the service life of components and the precision of torque control.

Description

technical field

[0001] The invention relates to a toothed part structure of a tool. Background technique

[0002] Various tools use the principle of leverage to screw and lock the screw to achieve the effect of tightening or loosening, so the screw can be assembled and combined with various industrial components. General industrial finished products need to use various types of screws due to structural differences, and apply different degrees of torque to assemble and fix them. In order to accurately control the torque applied by tools to the screws, the tool industry has begun the development and research of torque control structures. The torque control structure is gradually implemented and applied to tool items such as wrenches, screwdrivers, and adapter tools;

[0003] Among them, such as the U.S. Patent No. 7150212 "torque screwdriver" patent, the structure generally consists of an adjustment block, a scale block, an elastic member, and a pair of tooth-shaped correspon...
