[0030] The adjustment mechanism 4 includes an adjustment unit and a reset unit;

[0031] The adjusting unit is used to adjust the height of the tray 3;

[0032] The reset unit is used to provide an automatic reset force for the limit of the movement of the adjustment unit;

[0033] The adjustment unit includes a stop rod 401, a push rod 402, a pull rod 403, a limit block 404, and a limit slot 405;

[0034] The push rod 401 is rotatably mounted in the driving inner cavity of the base 1, and the push rod 401 is used to provide thrust for the vertical movement of the tray 3;

[0035] The push rod 402 is axially slidably installed in the inner cavity of the base 1 and extends to the outer wall of one end of the base 1. The push rod 402 is used to give a thrust to the stop rod 401 to rotate;
