[0025] It should be noted that a through hole is opened in the top of the cavity 8. When the sliding plug 9 slides sealingly on the inner wall of the cavity 8, the through hole can balance the pressure inside the cavity 8 to ensure that the sliding plug 9 can slide normally.

[0026] An exhaust mechanism is installed in the slide groove 4, and the exhaust mechanism includes an exhaust port 14 opened on the inner wall of the slide groove 4, a vertical groove 15 is opened at the bottom of the exhaust port 14, and a sealing plate 16 is sealingly and slidably connected to the inner wall of the vertical groove 15, a sealing port 17 cooperating with the sealing plate 16 is opened at the top of the exhaust port 14, and a sealing gasket is glued to the inner wall of the sealing port 17, a third spring 18 is fixedly connected between the bottom of the vertical groove 15 and the sealing plate 16, and a paddle 19 is fixedly connected to the side wall of the sealing plate 16.

[0027] A limit plate 20 is fixedly connected to the inner wall of the slide groove 4 , and the limit plate 20 can limit the sliding position of the slide plate 5 to prevent the slide plate 5 from sliding out of the slide groove 4 .

[0028] In the utility model, when the drawer cabinet 2 needs to be raised, the foot is placed on the pedal 13, and then the pedal 13 is repeatedly stepped down. Under the action of the stepping and the second spring 121, the slide plug 9 will slide back and forth in a sealed manner on the inner wall of the cavity 8, and then the external air will be drawn into the cavity 8 through the air inlet pipe 10, and then the air in the cavity 8 will be squeezed into the slide groove 4 through the air supply pipe 11, the pressure in the slide groove 4 will increase, and then the slide plate 5 will slide upward in a sealed manner on the inner wall of the slide groove 4, driving the fixing rod 6 to move upward, driving the drawer cabinet 2 to move upward, and the height of the drawer cabinet 2 is adjusted.

[0029] By pressing the paddle 19 downward, the sealing plate 16 is driven to slide downward into the vertical groove 15, and then the exhaust port 14 is opened, and the air in the slide groove 4 is discharged through the exhaust port 14, and the pressure in the slide groove 4 is reduced. Under the action of the first spring 7, the slide plate 5 will slide downward in a sealed manner, driving the fixing rod 6 to move downward, and then driving the drawer cabinet 2 to move downward, thereby lowering the height of the drawer cabinet 2.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
