Abstract
The utility model discloses a clamp device used for fixing a position of a frame. The clamp device comprises a fixing plate, a plurality of springing-ejector mechanisms and a plurality of turnover mechanisms, wherein a limiting mechanism which is used for limiting the movement of the frame in a horizontal plane is arranged on the fixing plate, the plurality of the springing-ejector mechanisms are used for springing and pressing the frame on the fixing plate, and the plurality of the turnover mechanisms are used for driving the springing-ejector mechanisms to turnover relative to the frame. The springing-ejector mechanisms spring and press the frame on the fixing plate.
