Operating key for stationary and driven tool holders

A system comprising:

• a driven or stationary tool holder with a housing, a tool holding fixture and a tool clamping system comprising an operating device configured to actuate a clamping mechanism, wherein the operating device comprises a bolt rotatably mounted in the housing of the driven or stationary tool holder, and wherein the operating device comprises a guide plate;
• a torque-providing device comprising at least one of a lever arm, a screwdriver, a torque wrench, an electromechanicaly, pneumatically or hydraulically driven wrench, and an industrial robot;
• and
• a drive and locking device that is configured to transmit torques from the torque-providing device to the operating device of the tool clamping system of the driven or stationary tool holder, the drive and locking device having a pin, wherein the pin comprises:
• a distal portion that is configured for form-fitting torque transmission between the drive and locking device and a socket of the bolt of the operating device of the tool holder, wherein the distal portion of the pin includes at least one first locking device comprising at least one of a spring ring, a spring-loaded machine element, a spring-loaded ball, a locking ball and a spring-loaded bolt, and wherein the first locking device of the pin is configured to engage with at least one recess of the socket of the bolt of the operating device;
• and
• a proximal portion that comprises a cylindrical structure, wherein the cylindrical structure of the proximal portion of the pin includes at least one second locking device comprising at least one of a spring ring, a spring-loaded machine element, a spring-loaded ball, a locking ball, and a spring loaded bolt, and wherein the second locking device of the pin is configured to lock the drive and locking device to the guide plate of the operating device.
