Abstract

The invention discloses an impact wrench which comprises a main shaft, an impact block and a driving shaft; the impact wrench has an impact state and a rotation state, the impact wrench further comprises a rotation circle computing unit and a stop controller, the rotation circle computing unit records the rotation circles of the driving shaft in the rotation state, and the stop controller controls stop of the impact wrench when the rotation circles reach the preset value.Compared with the prior art, the impact wrench can loosen a workpiece on a subject matter and can also intelligently control the workpiece to be unscrewed from the subject matter incompletely, the operation is convenient, the efficiency is high, and the impact wrench better meets the working habit of an operator.

Description

technical field [0001] The invention belongs to the technical field of impact wrenches, in particular to an impact wrench capable of automatic shutdown. Background technique [0002] Generally, the functions of a hand-held electric tool such as an impact wrench include tightening or loosening nuts and the like. However, the existing impact wrench is easy to directly unscrew nuts and other workpieces from the target object, which not only leads to inconvenient operation (the operator also needs to pick up the unscrewed nuts, screws and other workpieces), but also may cause nuts , The loss of screws. Contents of the invention [0003] The purpose of the present invention is to provide an impact wrench, which can make the impact wrench only loosen nuts and other workpieces from the target to the extent that they can be removed manually, and avoid unscrewing them directly. [0004] Correspondingly, in order to solve the above technical problem, in an embodiment provided by t...
