[0040] Specifically, the support plate 211 is arranged in a long inclined table structure, and the height gradually decreases from the end close to the swing mechanism 22 to the end away from the swing mechanism 22; the U-shaped plate 212 is arranged at the top middle position of the support plate 211, the opening faces upward, and the side wall is arranged in the same direction as the support plate 211. The patient can place the lower leg wearing the leg fixing belt 11 from above the U-shaped plate 212 to the inside of the U-shaped plate 212; the air bag 213 at the bottom wall of the U-shaped plate 212 can more comfortably lift the position of the lower leg, the air bags 213 at the side walls can extrude and fix the lower leg from both sides, and by differentially setting the inflation heights of the air bags 213 at the side walls, a good positioning effect can be achieved; the air pump interface 214 can be connected with an external high-pressure air pump, the high-pressure air pump is a vortex air pump for blowing and sucking, the special blade design of the high-pressure air pump has the characteristics of high pressure, large air volume, low noise, high temperature resistance, etc., and the air pump interface 214 is installed on the support plate 211, which is convenient for quickly inflating or deflating the air bag 213 and has the function of adjusting the extrusion force of the air bag 213 on the lower leg part.

[0041] With reference to the above Figure 3 , 4 The swing mechanism 22 in the embodiment includes a base 221, a swing arm 222, and a driving mechanism 223. The base 221 is horizontally and slidably connected with the support plate 211. The swing arm 222 is arranged at the left and right sides of the base 221, respectively. The output end of the driving mechanism 223 is connected with the lower end of the swing arm 222, and is used to drive the back-and-forth swing of the upper end of the swing arm 222.

[0042] Specifically, the upper surface of the base 221 is parallel to the upper surface of the support plate 211, the bottom of the base 221 is arranged in a U-shaped structure, the base 221 includes a groove 2211 and a first locking structure 2212, the groove 2211 is arranged at the inner wall of the left and right sides of the base 221, respectively, the left and right sides of the support plate 211 are respectively provided with a sliding strip 2111 matched with the groove 2211, and the first locking structure 2212 is arranged at the left and right sides of the base 221 and is used to limit the relative movement of the groove 2211 and the sliding strip 2111; preferably, the length of the sliding strip 2111 is greater than the length of the groove 2211, the first locking structure 2212 adopts a threaded locking structure, one end of which is rotatably arranged at the outside of the base 221, the other end of which is threadedly connected with the base 221 and penetrates into the inside of the groove 2211, when the one end of the first locking structure 2212 is tightened from the outside of the base 221 to the inside, the other end can generate an abutting force on the sliding strip 2111, so as to lock the relative position of the groove 2211 and the sliding strip 2111, and if the first locking structure 2212 is rotated in the opposite direction, the locking can be released.

[0043] It can be understood that when the calf part of the patient is fixed by the air bag 213, the horizontal position of the swing arm 222 needs to be adjusted according to the specific position of the foot sole, so that the action of the ankle pump training is more standard, and better training effect can be obtained. Preferably, the driving mechanism 223 is installed on the side surface of the base 221, the output end is connected with the lower end side surface of the swing arm 222, and the rotating direction is the same as the swinging direction of the swing arm 222.

[0044] The swing arm 222 in the embodiment is provided in a telescopic rod structure, including an outer tube 2221, an inner rod 2222 and a second locking structure 2223. The lower end of the outer tube 2221 is connected with the output end of the driving mechanism 223, the inner rod 2222 is telescopically arranged at the upper end of the outer tube 2221, and the second locking structure 2223 is arranged close to the upper end of the outer tube 2221 and used for limiting the relative movement of the inner rod 2222 and the outer tube 2221.

[0045] Specifically, the second locking structure 2223 adopts a threaded locking structure, one end of which is rotatably arranged outside the outer tube 2221, and the other end is threadedly connected with the outer tube 2221 and penetrates into the inside. When the one end of the second locking structure 2223 is tightened from the outside of the outer tube 2221, the other end can generate an abutting force on the inner rod 2222, so as to lock the relative position of the inner rod 2222 and the outer tube 2221. If the rotation direction is reversed, the locking can be released. It can be understood that the extension length of the inner rod 2222 is adjusted by the second locking structure 2223, so that the upper end of the inner rod 2222 can extend to both sides of the foot fixing belt 12, so as to adapt to the foot length of different patients and ensure that the action of the ankle pump training is more standard. In addition, the upper end of the inner rod 2222 is provided with a through hole 2224, so as to facilitate the binding and fixing of the tie belt 14 and the upper end of the inner rod 2222.

When the upper end of the outer pipe 2221 swings, the clamping piece 226 is driven to slide on the arc-shaped notch 225. It can be understood that after the upper end of the inner rod 2222 and the foot fixing belt 12 are fixed by the lacing 14, the swing arm 222 will be subjected to the inward pulling force of the foot fixing belt 12. When the swing arm 222 is arranged on the inner side of the vertical plate 224, the clamping piece 226 and the vertical plate 224 can provide a reverse pulling force for the outer pipe 2221. When the swing arm 222 is arranged on the outer side of the vertical plate 224, the clamping piece 226 and the vertical plate 224 can provide a reverse supporting force for the outer pipe 2221, so as to avoid that the swing arm 222 is easily bent due to excessive length.
