PROBLEM TO BE SOLVED: To provide a clamping system with an improved storage and handling ability, and a safety locking function ensuring that the pallet cannot get off from the chuck in case the ordinary operational clamping force is overcome.SOLUTION: Rotational motion of a drawbar 1.2 is guided and determined by means 2.7, 2.6, 2.4, 3 provided in a chuck 1.1 interacting with drawbars 1.2, 2.13. The drawbar 1.2, which is turnably journaled and mounted in an inner guidance channel 4, is form-locking designed with respect to the inner guidance channel 4 and with respect to the chuck 1.1 to impede the extraction of the drawbar 1.2 out of the chuck 1.1, regardless of whether the drawbar is in clamped or unclamped/released state. |
