摘要： The invention provides a power tool including an improved slip clutch assembly for transmitting torque from a motor-driven driving member to the rotatably driveable output shaft of the tool. The clutch assembly includes an annular clutch gear around the output shaft. The clutch gear meshes with the driving member and includes circumferentially spaced pockets that correspond to circumferentially spaced, conically-shaped detent depressions in the output shaft. The clutch assembly also includes a plurality of ball members each positioned in one of the pockets in the clutch gear. The ball members are spring-biased toward seated positions in the detent depressions to engage torque transmission between the clutch gear and the output shaft. When subjected to an overload torque, the ball members unseat from the detent depressions with a ratcheting action to disengage torque transmission between the clutch gear and the output shaft.
