the utility model provides a clamping device, includes the mount pad, the mounting groove has been seted up to the inboard of mount pad, the inside slidable mounting of mounting groove has the sliding plate, the outside fixed mounting of mount pad has the cylinder, the output and the sliding plate fixed connection of cylinder, the both ends of sliding plate all rotate through the round pin axle and install head rod, two the one end that the sliding plate was kept away from to the head rod all rotates through the round pin axle and installs the second connecting rod, two the one end that corresponding head rod was kept away from to the second connecting rod articulates there is fan-shaped pinion rack, the equal slidable mounting in both sides of mount pad has the rack, two the rack meshes with corresponding fan-shaped pinion rack respectively, two the equal fixed mounting in tip of rack has the grip block, grip block and corresponding rack mutually perpendicular.

Preferably, a sliding groove matched with the rack is formed in the inner side of the mounting seat, and the rack can slide in the sliding groove.

Preferably, the end of the mounting seat is provided with a guide groove matched with the clamping plate, and the mounting seat can be slidably connected in the guide groove.

Preferably, a plurality of anti-skid protrusions are fixedly mounted on the inner side of the clamping plate and are uniformly distributed on the clamping plate.

The utility model provides a pair of clamping device, beneficial effect lies in: make the sliding plate remove through the cylinder to make the head rod drive the second connecting rod and rotate, after the head rod contacts with fan-shaped pinion rack, promote fan-shaped pinion rack like this and rotate, and then drive two racks in opposite directions or back of the body removal, make two grip blocks in opposite directions or back of the body removal, this has just realized the centre gripping to the product and has loosened, owing to adopt gear engagement's form, this has just so greatly increased holistic stability.
