The invention relates to the technical field of clamps, in particular to a rapidly-and-evenly-pressing pressing plate. The pressing plate comprises a base, pressing plate bodies, an identical arm lever and a hydraulic cylinder; the hydraulic cylinder is vertically arranged, a piston rod of the hydraulic cylinder upwards extends into the portion, inside the base, of the top end of the hydraulic cylinder, the middle of the identical arm lever is connected with the piston rod of the hydraulic cylinder, the number of the connecting rods and the number of the pressing plate bodies are two, the connecting rods are symmetrically arranged in the base, the bottom ends of the connecting rods are hinged to the end of the identical arm lever, and the top ends of the connecting rods extend out of the upper portion of the base to be hinged to the middles of the pressing plate bodies arranged at the top of the base, the pressing plate bodies are symmetrically arranged at the top of the base and correspond to the connecting rods, the back ends, close to the edge of the top of the base, of the pressing plate bodies are hinged to a seat, a cavity is formed in the portion, corresponding to the identical arm lever, of the interior of the base, hydraulic drive is achieved, the pressing plate bodies run at the same time to press workpieces, operation is convenient, and even pressing is achieved.
