The cover plate body is located inside the housing and further includes a reinforcement component. The reinforcement component includes a top plate, a mounting block, a slider, a driving mechanism, two ejector rods and two connecting rods. The top plate is fixedly connected to the cover plate body and is located above the cover plate body. The mounting block is fixedly connected to the cover plate body and is located below the cover plate body. The mounting block has a mounting cavity.
