Product design model storage device facilitating taking and placing

The invention discloses a product design model storage device facilitating taking and placing. The device comprises a shell, a fixed rotating device and a connecting device, a hinge is arranged on the outer wall of the shell, the shell is rotatably connected with a cover plate through the hinge, a fixed column is fixedly connected to the upper part of the inner wall of the shell, a lifting plate is arranged in the shell, a second sliding groove is formed at the top of the lifting plate, and push rods are arranged at the two sides of the top of the lifting plate. Through air holes, a filter shell is connected with an external air pump, air in the shell can be sucked into the filter shell through the air holes by starting the air pump, and the flow formed by the air drives filter plates to rotate, so that the multiple groups of filter plates can adsorb impurities in the air, the impurities are prevented from sliding on the surface of a metal product, the metal product is protected, meanwhile, the air passes thr
