摘要： A device for tightening a bolt or a nut has a tightening socket which is releasable from biting engagement with the bolt or nut by disengaging a clutch in a rotation transmission system after completion of tightening, and which is made readily removable from the bolt or nut. The device is characterized in that it comprises power transmission means for coupling a socket drive motor to the socket for power transmission, the clutch incorporated in the power transmission means for selectively effecting or interrupting power transmission from the motor to the socket by a sliding movement, and clutch control means for selectively moving the clutch to an engaged position or a disengaged position. The clutch is moved to the disengaged position by the clutch control means after the motor is deenergized, whereby residual torque delivered by the motor to the bolt or the nut is removed to preclude biting engagement of the socket with the bolt or nut.

摘要： A device for fastening and loosening threaded members which has a socket mechanism at its forward end for engaging the threaded member and in which the torque of a motor rotatable in one direction is transmitted to the socket mechanism via a rotation transmission route including a planetary gear mechanism, forward-reverse rotation changing assembly and bevel gear mechanism. The bevel gear mechanism comprises a drive bevel gear coupled to the motor, and a pair of driven bevel gears opposed to each other in orthogonal relation to the axis of the drive gear and aligned with the axis of the planetary gear mechanism, the driven bevel gears being in mesh with the drive gear. The rotation changing assembly comprises an output shaft rotatably extending through the driven gears, and engaging means for selectively engaging one of the driven gears with the output shaft for the engaged gear to rotate with the shaft or disengaging the gear from the shaft. The output shaft is coupled to the planetary gear mechanism.
