Clamp for transferring workpieces

The utility model relates to the technical field of part production and machining, and particularly discloses a clamp for transferring a workpiece, which comprises a clamping jaw for grabbing a part, a disc-shaped bracket is hinged to the top of the clamping jaw, a lifting hook for grabbing the part is hinged to the bottom end of the clamping jaw, and a telescopic rod is hinged between the inner side wall of the clamping jaw and the inner side wall of the lifting hook. And a limiting structure for adjusting and limiting the extendable angle between the clamping claw and the lifting hook is arranged between the clamping rotor and the lifting hook. The utility model aims to solve the problems that in the part transferring process, due to the fact that the expansion angle of a clamping jaw is limited, when disc-shaped parts with large diameters are transferred, new clamping jaws need to be used so as to grab the parts with the large diameters, however, the clamping jaws are heavy and troublesome to replace durin
