  • Patent number: 11667025
    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.
