The two upper supporting plates 41 move in a manner that one sliding sleeve 412 is respectively disposed on each of the two upper supporting plates 41, and the sliding sleeve 412 is sleeved on the fixing rod 20 and can axially move on the fixing rod 20, that is, the two upper supporting plates 41 axially move on the fixing rod 20 through the corresponding sliding sleeves 412 respectively. In order to facilitate the position of the upper supporting plate 41 on the fixing rod 20 to be limited, a locking member is arranged on the sliding sleeve 412 and specifically is a bolt, the bolt transversely penetrates through the sliding sleeve 412 and is in threaded fit with the sliding sleeve 412, the bolt is screwed, the tail end of the bolt is abutted against the side face of the fixing rod 20, the position of the upper supporting plate 41 on the fixing rod 20 can be limited, and when the upper supporting plate 41 needs to be moved, the bolt can be loosened.

Two sliding sleeves 412 are arranged on two upper supporting plates 41 one above the other, as shown in fig. 1 and 2, two sliding sleeves 412 are respectively located on two sides of the upper tray 40, and compared with a mode that two sliding sleeves 412 are arranged on the same side of the upper tray 40, the structure of the mode is more reasonable, and two upper supporting plates 41 can be conveniently moved to a mutually flush state. Specifically, as shown in fig. 1 to 6, a first height difference is provided between the bottom end of the upper sliding sleeve 412 and the bottom surface of the upper supporting plate 41 connected thereto, a second height difference is provided between the bottom end of the lower sliding sleeve 412 and the top surface of the upper supporting plate 41 connected thereto, and the first height difference is the same as the second height difference, and when the upper supporting plate 412 is moved to make the sliding sleeve 412 arranged on one of the upper supporting plates 41 contact with the other upper supporting plate 41, as shown in fig. 4, the first height difference and the second height difference are matched with each other, so that the two upper supporting plates 41 are flush with each other, and together form the complete upper tray 40.
