Abstract:
1. A power tool with two cutting wheels ( 11 , 12 ), which rotate past each other in opposite directions and rest directly against each other, which are driveable by two drive spindles ( 14 , 15 ) disposed concentrically to each other, and with a tool fitting ( 13 ) for the cutting wheels ( 11 , 12 ), which has a first support flange ( 18 ) non-rotatably connected to the hollow outer drive spindle ( 14 ) and a second support flange ( 24 ) that is non-rotatably connected to the inner drive spindle ( 15 ), which provide a centered support and a form-fitting rotary slaving for the cutting wheels ( 11 , 12 ), and has clamping means for securing the form-fitting engagement between the cutting wheels ( 11 , 12 ) and the support flanges ( 18 , 24 ), wherein said clamping means have a screw part, which supports the second support flange ( 24 ) and whose end is screwable directly by hand without tools into the inner drive spindle ( 15 ), and have a clamping part, which is actuatable by hand, presses the second support flange ( 24 ) axially against the inner drive spindle ( 15 ), and clamps the second support flange ( 24 ) in relation to the screw part, and wherein the screw part has a threaded bolt ( 27 ) loosely supporting a clamping plate ( 29 ), and the clamping part is a clamping lever ( 28 ), said clamping lever ( 28 ) being pivotably affixed to threaded bolt ( 27 ) and said clamping lever ( 28 ) having an eccentric cam ( 35 ) formed onto said clamping lever ( 28 ), said eccentric cam ( 35 ) being formed so that when the clamping lever ( 28 ) is pivoted out of a position pointing in the direction of the threaded bolt axis ( 271 ), the eccentric cam ( 35 ) comes into contact with the clamping plate ( 29 ) supported on the second support flange ( 24 ).
