摘要

The structure has an elastic support (60) embedded between a pressure block and an operating bolt. The block and the bolt are arranged on a wedge (11) of a main body. The bottom of the block has a wedge (52) that is connected at its top to a passage opening (51). Upper side of the support presses a grip, when the wedge (52) presses against the grip, so that the grip experiences a counter force and is in a closed position.
