  • Publication number: 20230124236
    Abstract: A screw-tightening tool includes a housing, a motor, a spindle, a first clutch and a second clutch. The first clutch is operably coupled to an output shaft and the spindle, and is configured to transmit power from the output shaft to the spindle only when the output shaft is rotationally driven in a first direction. The second clutch is operably coupled to the output shaft and the spindle, and is configured to transmit the power from the output shaft to the spindle only when the output shaft is rotationally driven in a second direction. An output rotation speed of the spindle when the power is transmitted via the first clutch is different from an output rotation speed of the spindle when the power is transmitted via the second clutch, in response to the same rotation speed of the output shaft of the motor.
