The present invention relates to a clutch device for electric machine tool. The electric machine tool can be driven rotatably and impactively , wherein the percussion arrangement (32) can selectively separate from the principal axis (23) of the driving insert cutter or connect to the principal axis. An intermediate shaft (10) is disposed between the armature shaft (22) of the driving motor and the principal axis (23) to transferring the drive energy. It is suggested that the switch of the operation mode of the electric machine tool can be realized by the axial motion of the intermediate shaft (10). |
