technical field

The utility model relates to a buckle connection impact wrench. The utility model belongs to the technical field of an impact wrench.

Background technique

An impact wrench is a tool used to drive screws, bolts, clamps, etc. An impact wrench generally includes a drive motor, a gear reduction mechanism, and an impact device, wherein the impact device includes an active impact block, a passive impact block, a working shaft, and the like. The active impact block is rotationally driven by the output shaft of the gear reduction mechanism, and the passive impact block can be engaged with the active impact block to be rotationally driven. The working shaft is connected to the passive impact block and is driven to rotate by the passive impact block, wherein the active impact block can be selectively disengaged from the passive impact block when the load on the working shaft increases to a certain value, and then driven by the rotation of the output shaft The bottom re-engages with the passive impact block, thereby exerting intermittent impact on the working shaft in the direction of rotation.

The structure of the existing impact wrench can only change the motor speed by electronically adjusting the input current to realize the adjustment of the impact torque. On the host of the impact wrench or externally connected, this installation method limits the capacity and power of the battery pack, the battery pack’s battery life is short, the host is heavy, and workers working at heights are labor-intensive and prone to fatigue.

To sum up, in order to solve the problems existing in the prior art, there is an urgent need to invent a snap-fit connection impact wrench that is easy to assemble, easy to disassemble, has good sealing performance, is convenient for operators to operate, and reduces the labor intensity of operators.
