The left panel and the right panel are both formed by connecting two or more sideboards through rotatable connectors. A rotatable connection end of the bottom panel is connected to a lower part of the rear frame through a rotatable connector. A movable end of the bottom panel braces against the front frame. An inner side of each of the two ends of the rear frame is provided with a vertical edge strip. One end of each of the left panel and the right panel is connected to the vertical edge strip through a rotatable connector, and the other end is connected to the front frame. The top cover is connected to the front frame through a connector.
