Location structure of head of torque tool

Abstract

A head positioning device of torque tool includes: a hollow bar body, a positioning component and a head. Among them, one end of the hollow bar body has a handhold and a rotating component, the inner part of the hollow bar body is equipped with a torque force device, the end far away the handhold is combined with the head through the positioning component; the positioning component consists of a recess and a proud 22, the recess consists the first plane group and a second plane group which is installed in opposite direction and the angle difference between which is 90 degrees, and one end of the head far away positioning component is equipped with a ratchet device to making the invention has a rotating locking workpiece and a function of testing the torque force valve.

Description

technical field [0001] The invention relates to a head positioning structure of a torque tool. Background technique [0002] As shown in Figure 7, it is an existing torque wrench, which has a hollow shaft 61, a driving part 62 and a handle part 7, which uses the rotation of the handle part 7 so that it is located on the hollow shaft A second rod 611 in the 61 can support a first rod 612 by the interaction force between the two rollers 63, so that the second rod 611 can press the first rod 612 by the above-mentioned active force, and The torque wrench has a set torque value, and the driving part 62 can be used to wrench the workpiece. [0003] And the torsion tool 8 of another kind of convertible driving part on the market, as Figure 8 and Figure 9 As shown, the driving part 82 is provided with a rectangular bump 83 protruding toward the direction of the hollow shaft 81, but because the bump 83 adopts a rectangular design, so that only the opposite sides can be used for c...

[0003] And the torsion tool 8 of another kind of convertible driving part on the market, as Figure 8 and Figure 9 As shown, the driving part 82 is provided with a rectangular bump 83 protruding toward the direction of the hollow shaft 81, but because the bump 83 adopts a rectangular design, so that only the opposite sides can be used for conversion, so that the driving The transformation between the handle portion 82 and the handle portion 84 must be a transformation with a difference of 180°. Therefore, when screwing a workpiece, it is often necessary to prepare two kinds of torque tools or two handle portions to complete the entire twisting action. , it is quite inconvenient to use, coupled with the increasing complexity and precision of today's machine tools, single-function torque tools can no longer meet the needs of users
