    Abstract: A device for holding and rotating a plate shaped article comprises a group of fixed pins and a group of pivot pins arranged along the circumference of the movable base in a manner that each pivot pin opposites a fixed pin, and also comprises magnetic bodies positioned within and outside two opposing sides of the pivot pins. Each of the pivot pins can be driven to rotate around its pivot back and forth under the magnetic repulsive force between two adjacent magnetic bodies, so as to release or clamp the plate shaped article. The present invention has advantages of simple structure, convenient and reliable action control, controllable clamping force and good compatibility with various processing chambers.
