9. The rehabilitation exercise device for ankle sprain of the elderly according to claim 8, characterized in that: The third moving mechanism comprises a mounting plate (901) fixedly connected to the side wall of the foot fixing plate (17), and the side wall of the mounting plate (901) is fixedly connected to a sleeve rod (902), the side wall of the sleeve rod (902) is sleeved with a sleeve tube (903), and the other end of the sleeve tube (903) is fixed to the side wall of the second moving block (802), the side wall of the second moving block (802) is fixedly connected to a threaded tube (905), and the threaded tube (905) is internally threadedly connected to a threaded rod (904), the other end of the threaded rod (904) is rotatably connected to the side wall of the mounting plate (901), and the side wall of the mounting plate (901) is fixedly connected to a motor (906), and the output end of the motor (906) is fixed to one end of the threaded rod (904).

10. The method for using the elderly ankle sprain rehabilitation exercise device as claimed in claim 9, characterized in that: The following steps are involved: S1: When rehabilitation exercises are required, the foot fixing plate (17) is first rotated and adjusted so that the second groove (18) is directly opposite to the leg support plate (12). Then, the electromagnet (506) is powered off. At this time, under the action of the spring (602), the first moving block (502) slides upward along the side wall of the T-shaped guide rod (601), and the first moving plate (401) drives the push block (402) to move upward, so that the push block (402) abuts against the top of the foot fixing plate (17), thereby enabling the foot fixing plate (17) to swing and limit its position, thereby preventing it from swinging at will; S2: Then, the elderly patient lies on the bed, and at the same time, places the calf on the first groove (13) of the leg support plate (12) for support, and places the foot in the second groove (18) of the foot fixing plate (17). Then, the motor (906) is started by the remote control (10). The rotation of the motor (906) drives the rotation of the threaded rod (904), thereby driving the second moving block (802) to move away from the mounting plate (901), and drives the second fixed rod (805) and the plurality of racks (806) to move through the first fixed rod (803) and the second moving plate (804). When the rack (806) moves, it drives the gear (801) and the rotating shaft (702) to rotate, thereby driving the rotating block (703) and the arc frame (23) to rotate, and makes the silicone block (24) abut against the foot, thereby fixing the foot; S3: After the elderly person's foot is fixed, the electromagnet (506) is energized, and the iron block (504) is attracted, so that the first moving block (502) slides downward along the T-shaped guide rod (601). At the same time, the spring (602) is compressed and drives the push block (402) to move downward through the first moving plate (401), so that the push block (402) is separated from the foot fixing plate (17) and a sufficient distance is left. Then, the elderly person can perform rehabilitation exercises on the ankle joint. S4: During exercise, under the action of the universal ball (15), the foot fixing plate (17) can be swung at any angle, so that the foot of the elderly patient can move at any angle. At the same time, when the foot fixing plate (17) is swung, the universal ball (15) is driven to rotate through the first connecting rod (16), so that the round ball (22) is driven to slide on the friction plate (20) through the second connecting rod (21), and under the action of the counterweight plate (303), the hydraulic oil in the second fixing tube (302) can be squeezed, so that the sliding plate (202) can be pushed to move upward, and then the hemispherical cover (19) is driven to move upward through the support rod (203), so that there is a squeezing force between the round ball (22) and the friction plate (20), so that when the elderly patient is exercising, there is always resistance to the foot, ensuring that the ankle joint of the elderly patient can be exercised at any angle; S5: Furthermore, by adjusting the weight of the counterweight plate (303), the squeezing force between the friction plate (20) and the ball (22) can be adjusted, thereby adjusting the resistance during foot movement, thereby meeting the patient's rehabilitation training needs.
