  • POWER TOOL
    Publication number: 20220016753
    Abstract: A power tool includes an output shaft, a planet carrier, and a buffer mechanism. The planet carrier is configured to be rotatably connected with the output shaft to drive the output shaft during operation, and there is a gap between an inner side surface of the planet carrier and a circumferential surface of the output shaft. A buffer mechanism is provided on at least one of the inner side surface of the planet carrier and the circumferential surface of the output shaft near the gap. The buffer mechanism is configured not to actively apply pressure to the output shaft and the planet carrier, and to buffer the impact force between the output shaft and the planet carrier, when the output shaft slides relative to the planet carrier under the action of inertial force.
    Type: Application
