Cross the receiving area 74 of the notch 78 in the stop element 76 and the notch 32 being placed in the induction element 18.If described
It is in 24 following degree of connecting element in the notch 32 being placed in the induction element 18 of the percussion unit 12,
That is, material thickness of the induction element 18 in the fringe region of the notch 32 is seen along the principal elongation direction of connecting element 24
It examines and is arranged between the head zone 66 and the protrusion 30, and the head zone 66 of the connecting element 24 is located completely
In the notch 78 in being placed in the stop element 76, then the connecting element 24 is in a further step along the induction element
18 axial direction 50 is moved in the elongated bore region 72 of the notch 32.Here, the stop element 76 also moves.It is described
The connecting element 24 of stop element 76 and the coupling unit 22 is stationary relative to one another in the state that this is assembled.
In the state that one assembles, the radially 28 observation cloth of safety element 26 is formed by by the protrusion 30
It sets within the induction element 18 of the percussion unit 12.Connecting element 24 in the coupling unit 22 and the backstop
When element 76 moves, safety element 26 is formed by by protrusion 30 and is rabbeted as follows radially within the induction element 18
Fringe region behind, which is connected the elongated bore region 72 of the notch 32.It is formed by by the protrusion 30
Safety element 26 is observed from inside to outside along the radial direction 28 of the induction element 18, thick in the material of the induction element 18
It is arranged in before degree in the fringe region for the notch 32 being placed in the induction element 18.Because of the overall diameter of the protrusion 30
More than the elongation of the elongated bore region 72 of the notch 32, thus the protrusion 30 by corresponding connecting element 24 relative to institute
State radially 28 insurance outward of induction element 18.The head zone 66 of the connecting element 24 is along the induction element 18
Radial direction 28 is observed from inside to outside, is arranged in the merging guiding after the material thickness of the induction element 18 respectively
In the fringe region of notch 32 in element 18.Because the diameter of the head zone 66 of the connecting element 24 is more than the notch
The elongation of 32 elongated bore region 72, thus the head zone 72 of the connecting element 24 by corresponding connecting element 24 relative to
The radially 28 inwardly insurance of the induction element 18.
In order to prevent in axial direction 50 movement in the state that one assembles of connecting element 24 of the coupling unit 22
It returns in the receiving area 74 for the notch 32 being placed in the induction element 18, is not shown specifically one in a further step
Bearing unit 80 in axial direction 50 shift onto on the induction element 18 of the percussion unit 12.The bearing unit 80 is set
It sets and is used for another pair art technology relative to the slidably supported of beater mechanism shell 82 or setting for the induction element 18
Personnel are shown with the function of meaning.The bearing unit 80 in axial direction 50 observation positions fixedly with the induction element
18 couplings.It in axial direction 50 is left from the damping unit 20 in the connecting element 24 and stop element connected to it 76
Ground move when, the stop element 76 collided on the bearing unit 80 and limit in axial direction 50 movement, in institute
Before stating the receiving area 74 that connecting element 24 reaches the notch 32 being placed in the induction element 18.
Under the machining state of the percussion unit 12, the transmitting element 14 is inserted in axial direction 50 from described
Enter and be in direct contact a guide bushing 70 in the return movement that tool 16 leaves, the guide bushing is around the area in which the goods are in great demand of the connecting element 24
Domain 68 is extended up to is formed by safety element 26 by the protrusion 30.Here, the return impact punching of the transmitting element 14
Amount is by the connecting element 24 of the guide bushing 70 and the coupling unit 22 is passed on the stop element 76
Onto the damping element 64 of the damping unit 20.The stop element 76 in axial direction 50 is observed from the insertion work herein
Tool 16 moves with leaving, and compresses the damping element 64 of the damping unit 20 therefrom.It is mainly single by the damping therefrom
The damping element 64 of member 20 receives the energy for returning to impulse and is converted into friction energy or thermal energy.
