The invention relates to a lifting appliance and a using method thereof.The lifting appliance comprises a synchronous part, a rotating shaft, a guide rail, a sliding block assembly and a clamping jaw, at least three arc-shaped sliding grooves are formed in the synchronous part in a penetrating mode, the rotating shaft is rotationally arranged on the synchronous part, the sliding grooves are distributed around the rotating shaft, and the sliding grooves extend in the edge direction of the synchronous part with the rotating shaft as the center; at least three guide rails are fixedly arranged on the rotating shaft, one end of the sliding block assembly is slidably arranged on the guide rails, the other end of the sliding block assembly is slidably arranged in the sliding groove, and the clamping jaw is fixedly arranged on the sliding block assembly. According to the lifting appliance, through linkage of the sliding block assembly, the guide rail and the synchronous part, synchronous linkage of the multiple clamping jaws is achieved, the distance between the clamping jaws is reduced or increased, and therefore the coupler is clamped or released.
