- the cam gear element 82 of the fixing unit 20 is formed as a recess 84 in the fixing element 18.
- the cam gear element 82 of the fixing unit 20 forms a trajectory 86 which has a course parallel to the output shaft 16.
- cam gear member 40 of the cam gear 34 is formed as a movable cam gear member 88.
- the cam gear element 40 of the cam gear 34, in particular the movable cam gear element 88, is arranged at least partially within the fixing element 18.
- the cam gear element 40 of the cam gear 34 in particular the movable cam gear element 88, is arranged axially movable.
- the cam gear element 40 of the cam gear 34 in particular the movable Kurvengetriebeele- element 88, is arranged rotatably movable.
- the cam gear element 40 of the cam gear 34 in particular the movable cam gear element 88, at least partially engages in the cam gear element 38 of the output unit 14 and / or the cam gear element 82 of the fixing unit 20.
- the cam gear element 40 of the cam gear 34, in particular the movable cam gear element 88 has a contact surface 90, which for this purpose is provided to abut in at least one operating state on the unlocking pin 76.
- the output unit 14 has at least one torque transmission element 42.
- the torque transmitting element 42 is provided to transmit torque from the output unit 14 to an insertion tool 10.
- the torque transmitting element 42 is integral with the output member
- the torque transmission element 42 has an outer contour 68 in the form of an angled cross (see Fig. 3).
- the torque transmission element 42 is provided to form a positive connection with an insertion tool 10 by means of the outer contour 68 in the mounted state.
- the outer contour 68 of the torque transmission element 42 is congruent to the fixing element 18, in particular the locking part 66 of the fixing element 18, in at least one position of the fixing element 18 (see FIG. 3).
- the outer contour 68 of the torque transmission element 42 is formed in at least one position of the insertion tool 10 congruent with the connection device 46 of the insertion tool 10.
- the connecting device 46 in particular an inner contour 94 of the connecting device 46, is formed corresponding to a contour 48 of the fixing element, in particular of the locking part 18 of the quick-release device.
- This rotation causes, in particular by means of the thread 44 and / or the further thread 92 an axial deflection depending on a pitch S of the thread 44 and / or the further thread 92.
- the axial deflection is thus a / 360 ° * S.
- the clamping force of the fixing element 18 is thereby U times greater than the clamping force of the tension spring 32nd
