A disk-like rotary clamp means

The present invention discloses a rotating disc-like holding means, the movable base along the circumferential direction of the fixed jaw is divided into a set of events and jaw, each movable jaw and a fixed jaw, respectively, disposed opposite, and by its activity jaw side of the card is divided into a rotational direction of the magnet, which are driving the movable jaw to and fro about the rotation center by using a magnetic force between the magnets adjacent to repel each other, thereby placing on each disk of the fixed jaw clamp tighten or release, having a simple structure, convenient and reliable operation of the control mode, the clamping strength can be controlled and compatible with a variety of advantages process chamber.
