[0022] An electromagnetic valve 26 is penetrated through the inner wall of the box body 3, one end of the electromagnetic valve 26 is connected with a connecting pipe 10, the other end of the electromagnetic valve 26 is connected with the base end of the telescopic cylinder 18, and the end of the connecting pipe 10 away from the electromagnetic valve 26 is connected with the output end of the multi-stage pneumatic telescopic rod 9.

[0023] An armrest 25 is symmetrically fixedly disposed on the upper wall of the box body 3 , and an armpit support 27 is fixedly disposed between the armrest 25 and the box body 3 .

[0024] An iron block 8 is fixedly provided on the outer wall of one side of the air pressure control box 11, and an electromagnet 24 is fixedly provided on the upper wall of the base 1. The electromagnet 24 is energized and magnetically connected to the iron block 8. The air pump 12 is electrically controlled and connected to the electromagnet 24. When the air pump 12 is started, the electromagnet 24 is energized.

[0025] The air pump 12 is electrically controlled and connected to the solenoid valve 26; the air pump 12 sucks air into the air pressure control box 11, and the solenoid valve 26 is opened; the air pump 12 blows air into the air pressure control box 11, and the solenoid valve 26 is closed; the touch switch 15 is electrically controlled and connected to the solenoid valve 26.

[0026] A speed limiting block 6 is provided inside the connecting pipe 10 , and a small hole 7 is opened inside the speed limiting block 6 to limit the amount of gas passing through.

[0027] When in use, in the initial state, the solenoid valve 17 and the solenoid valve 26 are in the open state, and the air pump 12 is started first. At this time, the solenoid valve 26 is closed, and the electromagnet 24 is automatically opened, and the external gas enters the air pressure control box 11 through the air pump 12, and then enters the pneumatic telescopic rod 9. At this time, the pneumatic telescopic rod 9 is extended, and the electric push rod 7 drives the air pressure control box 11 to move to one side. At this time, the back plate 2 will slowly lift up, and the electromagnet 24 will tightly adsorb the iron block 8, thereby further improving the stability of the device; Then the patient holds the armrest 25, faces the box 3, stands steadily on the fixed pedal 23, and positions the feet through the fixed pedal 23, and then fixes the upper body through the armpit support 27, and then closes the air pump 12 and the solenoid valve 17 and manually opens the solenoid valve 26, the patient leans forward, and the backboard 2 is slowly tilted by the patient's weight, and the air pressure control box 11 moves toward the electric push rod 7. Since the air flow rate of the small hole inside the speed limit block is small, the gas in the pneumatic telescopic rod 9 will slowly enter the telescopic cylinder 18, the two-way telescopic cylinder 20 and the telescopic cylinder 22; At this time, the telescopic cylinder 18 will drive the fixed block 19 and the mounting plate 28 to move, thereby performing the first step of traction and stretching on the patient; at this time, the bidirectional telescopic cylinder 20 will drive the telescopic cylinder 22 and the fixed pedal 23 to move away from each other, thereby performing the second step of traction and stretching on the patient; at this time, the telescopic cylinder 22 will drive the fixed pedal 23 to move, thereby performing the third step of traction and stretching on the patient; During the traction and stretching process, the air pressure in the air pressure control box 11 will increase. When the air pressure in the air pressure control box 11 reaches a certain pressure, the guide column 14 and the water tank 13 move upward. When the stopper 16 contacts the touch switch 15, the touch switch 15 closes the solenoid valve 26, and the water volume in the water tank 13 is changed, so as to achieve the effect of adjusting the traction force. After the patient stretches and tractions for a certain period of time according to his own situation, the air pump 12 is turned on again, and the electromagnet 24 is also turned on accordingly. The air pump 12 injects gas into the air pressure control box 11. At this time, the pneumatic telescopic rod 9 pushes the backing plate 2 to make the backing plate 2 in a vertical state. The electromagnet 24 adsorbs the iron block 8 to improve the stability of the device. At this time, the patient can leave the device; When the device needs to be folded and stored, the electric push rod 7 is activated to retract, the solenoid valve 17 is opened and the air pump 12 is reversely activated, the solenoid valve 26 is automatically opened, and the air pump 12 sucks out the gas in the pneumatic telescopic rod 9, the telescopic cylinder 18, the two-way telescopic cylinder 20 and the telescopic cylinder 22, and the folding and storage of the device can be completed.

[0028] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
