The invention discloses a lifting appliance of a hinge type prefabricated block. The lifting appliance comprises a lifting disc and scissor type clamps, and is characterized in that the lifting disc is a square metal frame, and a hanging ring A is arranged at the center of the top of the lifting disc and is used for connecting a hook of a crane; four hanging rings B are arranged at four corners ofthe bottom of the lifting disc, and each hanging ring B is connected with two steel wires; the two steel wires connected to each hanging ring B are connected with one scissor type clamp; each scissortype clamp consists of a bent clamping piece A, a bent clamping piece B, and a clamping rod A and a clamping rod B which are respectively welded obliquely at the lower ends of the clamping piece A and the clamping piece B; each clamping piece A and one corresponding clamping piece B are connected with each other through a bolt; and the two steel wires connected to each hanging ring B are respectively connected to the upper ends of one corresponding clamping piece A and one corresponding clamping piece B. According to the lifting appliance, the lifting disc and the scissors type clamps are adopted, so that the gap among the prefabricated blocks is increased, mutual friction and collision are reduced, and the lifting appliance is convenient and practical.
