[0023] Working principle: The patient sits on the seat cushion 210 and turns around, placing their feet on the lifting unit 440. The lifting unit 440 descends, and the lifting frame 4411 presses the button on the top of the horizontal axis 430, transmitting a signal to the controller 470. The patient's feet directly contact the dustproof component 4434. When the connecting component 4410 descends, the armrest component 331 can rotate 90 degrees. At this time, the pull rope 420 connects the connecting component 4410 and the armrest component 331. The patient turns their body, placing their hands between the armrest component 331 and the L-shaped component 333, with their palms placed on the expansion airbag 332. The patient leans against the backrest component 2210, and the lower airbag 335 is compressed. The air inside the lower airbag 335 is discharged into the expansion airbag 332 through the hose 334 and the armrest component 331. When 332 expands, it can cooperate with the buffer to limit the patient's hand position. The patient's upper back compresses and pushes the external component 2223, which can drive the push plate 2224 to move through the light rod 2222. The push plate 2224 pushes the force-bearing component 2333 to rotate. When the outer frame 2332 rotates accordingly, the patient's head rests on the headrest component 2310 above the shoulder and compresses the upper airbag 2321. The air inside the upper airbag 2321 is vertically limited to the limiting airbag 2323 through the inflation tube 2322. The limiting airbag 2323 expands to limit the patient's shoulder position. Based on this, the patient's own weight can be used to limit the position of the patient's shoulder and hand through the cooperation of the limiting airbag 2323, the expanding airbag 332 and the L-shaped component 333, respectively, reducing interference to the doctor during dental treatment. After treatment, the patient can lift their head to reduce the internal pressure of the expansion airbag 332. The patient can move their hands to support their upper body, and then lift their leg to turn around. When the patient lifts their leg, the lifting frame 4411 is lifted by the elastic force of the second spring 4412, the pressure on the button is released, the controller 470 starts the motor 4432, and the spline shaft 4431 rotates to replace the part of the dustproof part 4434 covering the arc frame 4420 for the next patient.
