Abstract

A tool device comprises a first module and a second module that can be detached from the first module, the first module having a receptacle and the second module having an insertion part that can be inserted in the receptacle along an insertion axis. The insertion part can be rotated in the receptacle about the insertion axis between a locked position and an enabled position, the receptacle having a first projection and the insertion part having a second projection. In the locked position, the second projection engages behind the first projection in the direction of the insertion axis, and in the enabled position, the first projection enables the second projection to pass in the direction of the insertion axis, the receptacle preventing an activation of the tool device in an initial position and allowing activation of the tool device in a pressed-on position.

Claims

1. A tool device, comprising a first module and a second module that can be detached from the first module, said first module having a receptacle and said second module having an insertion part that can be inserted in the receptacle along an insertion axis which defines an insertion direction, wherein the insertion part can be rotated in the receptacle about the insertion axis in one rotational direction between a locked position and an enabled position, wherein the receptacle has a first projection and the insertion part has a second projection, wherein, in the locked position, the second projection engages behind the first projection in the insertion direction of the insertion axis, wherein, in the enabled position, the first projection enables the second projection to pass in the direction of the insertion axis, wherein the tool device has a lock with a locking position and an unlocking position, and wherein, in the locking position, the lock prevents a detachment of the second module from the first module, and in the unlocking position allows the detachment of the second module from the first module.

2. The tool device according to claim 1, wherein the lock has a bolt arranged on one of the first and second modules and a bolt slot arranged on the other of the first and second modules, and wherein, in the locking position, the bolt engages in the bolt slot, and in the unlocking position, said bolt is arranged outside of the bolt slot.

3. The tool device according to claim 2, wherein the other one of the first and second modules comprises the bolt slot.

4. The tool device according to claim 2, wherein the bolt moves, relative to the insertion axis, radially inwardly into the bolt slot during the transition from the unlocking position to the locking position.

5. The tool device according to claim 2, wherein the bolt moves, relative to the insertion axis, radially outwardly into the bolt slot during transition from the unlocking position to the locking position.

6. The tool device according to claim 1, wherein the lock has an actuation element which is connected to the bolt.

7. The tool device according to claim 2, wherein the lock has a bolt spring, which loads the bolt and the bolt slot toward one another.

8. The tool device according to claim 1, wherein, in the locking position, the lock blocks a shifting of the insertion part relative to the receptacle along the insertion axis, and in the unlocking position, the lock allows the shifting of the insertion part relative to the receptacle along the insertion axis.

9. The tool device according to claim 2, wherein the lock has a plurality of bolt slots arranged on the other one of the first and second modules.

10. The tool device according to claim 1, wherein the insertion part is rotatable in the receptacle between several locked positions and several enabled positions about the insertion axis.

11. The tool device according to claim 1, further comprising a catch having a catch element and a catch seat, wherein, in the locking position, the catch element engages in the catch seat.

12. The tool device according to claim 1, further comprising a safety device having a secured position and an unlocked position, wherein, in the secured position, the safety device prevents an activation of the tool device, and in the unlocked position, the safety device allows said activation.

13. The tool device according to claim 16, wherein the unlocking interlock has a first blocking element arranged on the first module and a second blocking element arranged on the second module, and wherein, in the enabled position, the first blocking element and the second blocking element block one another, and in the locked position, the first blocking element and the second blocking element are enabled to pass one another.

14. The tool device according to claim 1, wherein, in the locking position, the lock blocks a rotation of the insertion part in the receptacle about the insertion axis, and in the unlocking position, the lock allows the rotation of the insertion part in the receptacle about the insertion axis.

15. The tool device according to claim 2, wherein, during the transition from the unlocking position to the locking position, the bolt moves along the insertion axis into the bolt slot.

16. The tool device of claim 12, further comprising an unlocking interlock which, in an enabled position, blocks a transition of the safety device from the secured position to the unlocked position, and in the locked position allows the transition of the safety device from the secured position to the unlocked position.

17. The tool device according to claim 3, wherein the other one of the first and second modules has a connecting link which, relative to the other of the first and second modules, is rotatably arranged about the insertion axis and comprises the bolt slot.

18. The tool device of claim 6, wherein the activation element is rigidly connected to the bolt.

19. The tool device according to claim 2, wherein the lock has an actuation element which is connected to the bolt.

20. The tool device according to claim 2, wherein, in the locking position, the lock blocks a shifting of the insertion part relative to the receptacle along the insertion axis, and in the unlocking position, the lock allows the shifting of the insertion part relative to the receptacle along the insertion axis.
