Claim 0:
1. A positioning device, comprising:
a tool turret of a machine tool;
a tool holder on the tool turret;
a first positioning pin being secured to the tool turret and engaging a receptacle on the tool holder when the tool holder is attached to the tool turret, the receptable on the tool holder having a first sleeve engaging the first positioning pin, when the tool holder is in a mounted state in which the tool holder is attached to the tool turret, while the first positioning pin is contacting an inner circumferential surface of the first sleeve, the inner circumferential surface being part of an expanding part that expands elastically and flexibly in a direction away from the first positioning pin when the expanding part is engaged by the first positioning pin, both the first positioning pin and the first sleeve being fixed in the tool turret and in the tool holder, respectively, by a respective screw, connection, both the first positioning pin and the first sleeve having a respective continuous hollow duct, a respective point of action for an operating tool being within each of the hollow ducts, and the first positioning pin resting against the tool turret via an annular support part that is outside of the corresponding screw connection, and the first sleeve resting against the tool holder via an annular support part that is outside of the corresponding screw connection; and
a bending rod of a fixer, the bending rod releasably retaining the tool holder on the tool turret and extending through the hollow duct of the first sleeve and into the hollow duct of the first positioning pin.
