Abstract

A power tool includes a locking mechanism for locking the output shaft when the output shaft transmits torque to the motor shaft. The locking mechanism includes a shaft lock bracket connected to the output shaft to drive the output shaft; and a damping assembly including a first mounting portion connected to the output shaft, a second mounting portion connected to the shaft lock bracket, and a buffer part. The buffer part connects the first mounting portion to the second mounting portion. When the output shaft and the shaft lock bracket move relative to each other, the buffer part undergoes the torsional deformation to provide a buffer force that delays the movement of the output shaft relative to the shaft lock bracket.
