[0037] Working principle: The sliding frame 3, the top plate frame 4, and the sliding frame 5 are fixed together to form a whole, and then the right-angle plate 10 inside the sliding frame 5 provides support force. At this time, the connecting plate 11 is passed through the right-angle plate 10, so that the middle part of the connecting plate 11 can fit with the outside of the right-angle plate 10, and at the same time, the two sides of the connecting plate 11 will also fit with the two ends of the fixed plate 9, so that the connecting plate 11 can be supported.
