The swing plates 15 and the movable plates 14 are hinged to each other near the center. A fitting rod 17 is provided near the top of the inner cavity of the swing plate 15 and is fixedly connected thereto. The inner cavities of several recesses have support plates 3, and the corresponding sides of several support plates 3 are fixedly connected with guide plates 13 near the top.
