[0015] In the above scheme, the two rotating bars can rotate with each other in a cross form, so that the distance between the second rotating wheel and the first rotating wheel can be changed, which utilizes the parallelogram principle. The second rotating wheel is directly connected to the rotating bar for rotation or a mounting seat for mounting the second rotating wheel is provided at the end of the rotating bar, and the second rotating wheel is then rotatably arranged on the mounting seat for installation.

[0016] In one embodiment, a protrusion is provided at the end of the rotating bar connected to the first rotating wheel, and a limiting sliding groove matched with the protrusion is provided on the inner wall of the drying box.
