Abstract

The device has a bolting device body with recess assigned to a tool holder (10). A safeguard body (20) protects the bolting device body in the recesses. A control body (14) moves the safeguard body during a module movement of the tool holder into the machine from a bolting device position. A guide leads the control body during the module movement.
