Patent ID: 6910694

Claim:
An electrical tool, comprising a housing ( 1 ); a motor-driven hollow spindle ( 2 ) for supporting a working tool ( 3 ) and located in the housing ( 1 ); and a quick-action device for clamping the working tool ( 3 ) with respect to the hollow spindle ( 2 ), the quick-action clamping device having a clamping spindle ( 4 ) arranged in the hollow spindle ( 2 ) with a possibility of an axial displacement relative thereto, an elastic member ( 5 ) for biasing the clamping spindle ( 4 ) into a clamping position thereof, in which the working tool is clamped between a clamping flange ( 7 ) provided on a working tool-side end of the clamping spindle ( 4 ) and the hollow spindle ( 2 ), actuation means ( 24 ) for displacing the clamping spindle ( 4 ) against the biasing force of the elastic member ( 5 ) into an exchange position thereof, in which the working tool ( 3 ) is released, a compensator ( 15 ) arranged between the elastic member ( 5 ) and the actuation means ( 24 ) for interrupting action of the elastic member ( 5 ) on the clamping spindle ( 4 ) at least in the exchange position of the clamping spindle and in response to actuation of the actuation means ( 24 ), and damping means ( 22 ) having a predetermined length and a higher elasticity than the elastic member ( 5 ) and arranged between the elastic member ( 5 ) and the clamping spindle ( 4 ).
