ABSTRACT:
A device for driving a screwdriver spindle has a claw clutch and an over-detent clutch. The two clutches are arranged coaxially to each other and have coupling parts which are displaceable in an axial direction. Upon a first response of the over-detent clutch, the claw clutch is disengaged, a correspondingly axially displaceable coupling part of the claw clutch is then locked in a disengaged position by a disengageable safety which is simply a radially elastically expandable clamping sleeve which is connected to the claw-clutch and has a detent projection which protrudes radially inward. The screwdriver spindle on which the clamping sleeve is arranged has two circumferential grooves for engagement of the detent projection, the axial center-to-center distance of which is greater than the coupling stroke of the claw clutch.
