The inside is filled with counterweight liquid, a liquid inlet is opened on one side of the box body 11 near the top, and a sealing plug 19 is arranged on the inner wall of the liquid inlet. When performing oral treatment, the patient sits on the treatment chair. At this time, the adjustment mechanism 7 is started, and the adjustment mechanism 7 will drive the treatment chair and the patient to tilt, so as to facilitate the patient to be in a suitable position for the doctor's treatment. During this period, when the treatment chair tilts, one side of the leaning plate 5 will squeeze the top of the push rod 14. At this time, the push rod 14 will drive the push plate 13 and the piston plate 12 to slide downward after being squeezed. When the piston plate 12 slides downward, it will squeeze the counterweight liquid inside the box body 11.
