Title: ATTACHMENT DEVICE
Abstract:
The invention relates to an attachment device for arrangement on a handheld power tool (12a, 12b), having a tool receptacle (18a; 18b) for receiving a tool insert, and having at least one rotary hammer mechanism (20a; 20b) which, in at least one operating state, is provided for generating a rotary hammer impulse for hammer-action drive of the tool receptacle (18a; 18b). It is proposed that the rotary hammer mechanism (20a; 20b) has at least one planetary gear set (30a; 30b) which is provided for converting a rotational speed and/or a torque of an output shaft (32a; 32b) of the handheld power tool (12a; 12b) into a rotational speed and/or a torque of the tool receptacle (18a; 18b).
