When pulling it out, the limiting plate 2 (316) needs to be pressed to make the end of the limiting plate 2 (316) adapted to the limiting block (312) tilt up, and then the limiting plate 2 (316) can be taken out.

9. The pneumatic therapy device for pneumatic therapy combined with ankle joint exercise therapy according to claim 8, characterized in that: The belt member comprises two pulleys (216) fixedly connected to the outer wall of the rotating shaft (213) and the threaded rod (215), and the outer walls of the two pulleys (216) are provided with belts (217); When the pulley (216) at one end rotates, the pulley (216) at the other end is rotated by the belt (217).

10. A method for controlling an air pressure therapy device for combined air pressure therapy and ankle joint exercise therapy, using the air pressure therapy device for combined air pressure therapy and ankle joint exercise therapy as claimed in claim 9, characterized in that: The steps include: S1: At the second second when the pulse air pressure is maintained, the ankle joint trainer starts working and then starts the main unit (111), and the motor (212) is started by the main unit (111). When the motor (212) rotates, the shaft 1 (213) rotates on the ankle joint trainer housing (211), and when the shaft 1 (213) rotates, it drives the pulley (214) on its outer wall to rotate. At this time, the pulley (214) drives the pulley (214) on the other side through the belt (215), and the threaded rod (217) is driven to rotate with it. When the threaded rod (217) rotates, it drives the slide plate 2 (223) to move forward. When the slide plate 2 (223) moves, the slide plate 1 (222) is on the limit plate 1 (2 21), when the slide plate 1 (222) slides, the connecting rod (224) slides with it, when the connecting rod (224) slides, the hinge assembly (231) moves with it, when the hinge assembly (231) moves, the telescopic rod (232) moves with it, the movement of the telescopic rod (232) changes to a certain angle, when the telescopic rod (232) is pushed, it shrinks due to the angle change, when the telescopic rod (232) changes its angle, it rotates the rotating shaft 2 (234) on the fixed shell (233), when the fixed shell (233) rotates, it moves the pressing plate (235), and when the pressing plate (235) moves, the ankle joint moves, thereby achieving a motion-type treatment of the ankle joint; S2: Connect the ankle joint trainer housing (211) to the main unit (111) through the output line (114), and then connect the airway tube (313) to the limb pressure sleeve (112). When connecting, align the airway tube (313) with the connection port on the main unit (111), and then align the second limiting plate (316) with the reserved port on the fixed block (311), and then insert it into the reserved port. At this time, the second limiting plate (316) will be pushed upward by the limiting block (312). At this time, the second limiting plate (316) will tilt on the hinge block (315). When the second limiting plate (316) moves upward, it will pull the spring (317) upward. Then, the second limiting plate (316) can enter the reserved port on the fixed block (311), and the spring (317) will pull the second limiting plate (316) downward. At this time, the second limiting plate (316) will restrict each other with the limiting block (312), thereby achieving a limiting effect. Therefore, during the air pressure treatment, the air pressure treatment will not be stopped due to excessive pressure or external force. When the airway tube (313) needs to be removed, the second limiting plate (316) is pressed. When the second limiting plate (316) is pressed, it will move on the hinge block (315). At this time, the spring (317) will be pulled upward, so that the second limiting plate (316) can pass through the limiting block (312) smoothly. Thus, the second limiting plate (316) can be removed, and the airway tube (313) is then put into the cable management bag (113). Then, the limb pressure sleeve (112) is put on the leg that needs to be treated, and then the ankle joint that needs to be treated is placed on the ankle joint trainer shell (211), and the air pressure treatment is started first.
