(105) top, and at the same time, by controlling the start-up of the adjustment motor (108), the adjustment motor (108) drives the adjustment threaded rod (107) to rotate, thereby enabling the rotating adjustment threaded rod (107) to move the adjustment plate (109) to adjust the use height, and then under the position limit of the slide bar (103), the carrier plate (104) can carry the suction machine body (201) to adjust the use height, which is convenient for the user to adjust and use. When the suction machine body (201) is used in other use positions, the baffle (106) can be removed, and the carrier plate (104) can be flipped downward, so that the bottom of the carrier plate (104) can temporarily serve as a carrying plane for placing other medical equipment.
