Clamping and lifting device and method for lifting and mounting component

The invention relates to a clamping and lifting device for lifting and mounting a component. The clamping and lifting device comprises a left splint, a right splint and a clamp hook rivet, wherein a rivet hole and a hook hanging hole are formed in the left splint; the upper part of the left splint is hook-shaped; a rivet hole and a hook hanging hole are formed in the right splint; the upper part of the right splint is hook-shaped; the rivet holes in the left and right splints are riveted through the clamp hook rivet, so that the left and right splints form a scissors clamp, and the hook-shapedupper parts of the left and right splints form a clamp hook. When the scissors clamp is closed, the hook hanging holes in the left and right splints are overlapped, and the clamp hook has a clamp cavity for clamping the component. The clamping method comprises the following steps: opening the scissors clamp, and placing the component into the clamp hook; closing the scissors clamp, and placing the component into the clam
