Abstract (en)
[origin: EP0523477A1] A wrench with variable torque adjustment, in particular a wrench with torque cut-out, has a shaft, driven by a motor via a drive mechanism (2), for driving a tool as well as an adjusting device (28) for pre-setting a torque, during which the shaft (20) is separated from the drive mechanism (2) and/or the motor is cut out. In order to permit approximately the same torque characteristics when driving in hard and soft materials, a clutch (29) with variable release moment is provided in addition to the first adjusting device, the release moment of which clutch (29) can be set via a second adjusting device (13), the second adjusting device (13) being adjustable together with the first adjusting device (28). <IMAGE>
