10. The method of using a metal cabinet having a limiting structure according to any one of claims 1 to 9, comprising the steps of:

s1, aligning a limit groove (6) on the lower surface of a lifting table (3) with one end of a limit post (51), sliding the lifting table (3) along the limit post (51) through the limit groove (6) until the side wall of the lifting table (3) is blocked by a baffle plate (9), then rotating a rotating rod (54), enabling the shape of a hole on the side wall of the limit post (51) to be the same as that of the limit block (56), extruding the rotating rod (54) to the inside of the limit post (51) through a fixed disc (53) under the limit of a telescopic spring (52), driving a convex post 55 to move when the rotating rod (54) moves, extruding a locating pin (59), inserting one end of the extruded locating pin (59) into a locating hole of the limit groove (6), rotating the rotating rod (54) to be in situ after the shell wall of the limit post (51) moves between the two limit blocks (56), and enabling the rotating rod (54) to move under the blocking of the limit block (56), so that the locating pin (59) cannot be fixed in the locating hole (73) and the lifting table (3);

s2, according to different heights of users, a driving motor (71) can be enabled to work through a controller, at the moment, the driving motor (71) can drive a threaded column (72) to rotate, a first toothed chain wheel (74) can be driven to rotate along with the rotation of the threaded column (72), under the transmission of a toothed chain, the other first toothed chain wheel (74) can drive a threaded rod to rotate, meanwhile, a second toothed chain wheel (15) can drive a movable rod (14) to rotate, and a lifting plate (73) can be moved to the upper surface of a fixed plate (2) through threads on the outer surface along with the rotation of the threaded column (72) and the threaded rod, so that the position of a lifting table (3) is adjusted;

s3, when the movable rod (14) rotates, the fan blades (16) are driven to rotate, so that ventilation of air in the cabinet can be promoted, and the movable plate (13) is placed on bearing blocks (12) at different positions according to the size of things to be placed, so that the space in the cabinet is changed;

s4, the just cleaned object can be placed on the placing plate (101), at the moment, the limiting pin (103) can fix the object under the limit of the limiting spring (102), water on the object can flow into the water collecting frame (105) below through the water filtering holes (106), after the water in the water collecting frame (105) reaches a certain amount, the water collecting frame (105) is pulled out from the clamping strips (104) through the clamping grooves (107), and then the water in the water collecting frame (105) is cleaned, and after the water collecting frame (105) is fixed with the placing plate (101) through the same method.
