Diamond PCD (Poly Crystal Diamond) composite sheet clamp

The utility model discloses a diamond PCD composite sheet clamp which comprises a base plate, a bolt hole and a lock groove are formed in the side wall of one side of the base plate, a lock block is installed in an inner cavity of the lock groove in a sliding mode, a lock bolt and a plug pin are arranged on the surface of the lock block, a clamping plate is installed on the side wall of the other side of the base plate in a clamped mode, and a suction cup is arranged on the surface of the side, away from the base plate, of the clamping plate. Side supports are arranged at the bottoms of the side edges of the clamping plates. According to the diamond PCD composite sheet clamp, through the split type structural design of the base plate and the clamping plates, the clamping plates make full contact with a composite sheet, so that the contact area between the clamp and the composite sheet is increased, the composite sheet is adsorbed to the clamping plates through suction cups, and the clamping strength between t
