Abstract

The invention relates to a torque force spanner provided with a control unit, which comprises a body unit, a handle unit which is rotatably arranged on a pipe part and provided with at least one actuating hole and one clamping hole, a control ring, an elastic element arranged between the control ring and the handle unit, and at least one control unit, wherein the pipe part is provided with a plurality of shallow grooves; the control ring is provided with an inner annular surface, at least one abdicating groove which is concavely arranged on the inner annular surface and two positioning grooves which are concavely arranged on the inner annular surface; and the elastic element is provided with a first end part which presses a limit piece on the pipe part, a clamping part which is clamped with the clamping hole and a positioning part. When the control ring is at a first position, the abdicating groove is corresponding to the first end part, the inner annular surface is away from the first end part, and the positioning part is connected with one of the positioning grooves; and when the control ring is at a second position, the abdicating groove is separated from the first end part, the inner annular surface is close to the first end part, and the positioning part is connected with the other positioning groove. Through the rotary switch of the control ring of the control unit, the torque force spanner not only has the advantages of convenient and fast operation and definite positioning, but also can prevent the control unit from accidentally breaking.

Description

technical field [0001] The invention relates to a wrench, in particular to a torque wrench with a control unit which is not only easy to operate, fast and has clear positioning by means of the rotation switching of the control ring of the control unit, but also prevents the control unit from being accidentally broken. Background technique [0002] see figure 1 , figure 2 as shown, figure 1 It is a three-dimensional schematic diagram of the appearance of an existing wrench with preset locking torque value, figure 2 It is a partial sectional view of the combined structure of the existing wrench. An existing wrench that can preset the locking torque value includes a pipe fitting 1, a wrench 2 that is pivotally connected to the pipe fitting 1 and aligns with the pipe fitting 1 under normal conditions, and a wrench installed in the pipe fitting 1. And the actuating block 3 abutting against the end of the wrenching member 2, a compression spring 4 abutting against the actuat...
