Abstract (en)
[origin: EP0401548A1] In order to improve a power-driven screw-fastening tool having a drive (12) arranged in a housing (10), a screwing tool (34) and a screw-in depth cutoff, comprising a depth stop (68), which determines a screw-in depth and is held on the housing, and a coupling (22), which is arranged between the drive and the tool drive shaft (24) and can be changed, by axial displacement of the tool drive shaft, from a rest position in the direction of the drive to a working position, and which has a coupling element (104) driven by the drive and a coupling element (100) connected to the tool drive shaft, and also an intermediate coupling element (102) arranged between this coupling element, the intermediate coupling element forming, with a first of the coupling elements, a driving coupling and a releasing coupling, in such a way that said screw-fastening tool has, in addition to a screw-in depth cutoff, also has a screw-in torque cutoff, it is proposed that the screw-in depth cutoff can be switched over into a screw-in torque cutoff incorporating the releasing coupling as torque-limiting element. <IMAGE>
