[0030] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0031] Working principle: When the height of the tray 2 needs to be adjusted, two people stand in the front and rear positions of the tray 2, and at the same time insert the external rod into the through hole 12 on the side of the lower positioning plate 6, press the positioning block 10 back into the positioning hole 8, and then push the tray 2 forward or backward until the upper toothed connecting plate 4 is completely separated from the straight tooth groove 5 of the corresponding lower toothed connecting plate 3, so that the tray base 1 and the tray 2 can be separated. Then, according to the required height, find the straight tooth groove 5 of the upper toothed connecting plate 4 at the corresponding height and plug it horizontally with the lower toothed connecting plate 3, and push it from front to back or from back to front. When inserting, Two people in front and behind the tray 2 first press the positioning block 10 into the positioning hole 8, and release it when the lower positioning plate 6 covers the positioning block 10, and continue to push the tray 2 until the lower toothed connecting plate 3 and the upper toothed connecting plate 4 are fully aligned. At this time, the positioning block 10 will be pressed into the positioning groove 11 by the pressure of the positioning spring 9. Since the lower toothed connecting plate 3 and the upper toothed connecting plate 4 can only slide back and forth along the straight tooth groove 5, the lower positioning plate 6 and the upper positioning plate 7 can only slide vertically along the positioning groove 11, so that the tray base 1 and the tray 2 are stably assembled, easy to disassemble and assemble, and safe to use.
