The rear end cover 4 is installed on the upper guard plate 6, and the two upper straps 7 are respectively installed on the upper and lower sides of one end of the upper guard plate 6.

[0033] The lower fixation device 2 includes a lower guard plate 8 and two lower straps 9. The lower guard plate 8 is designed in the shape of the outer side of the lower leg, and the lower straps 9 are Velcro straps. The lower guard plate 8 is installed on the movable plate 12, and the two lower straps 9 are respectively installed on the upper and lower sides of one end of the lower guard plate 8, so that the upper guard plate 6 is attached to the patient's thigh and fixed by the upper strap 7, while the lower guard plate 8 is attached to the patient's lower leg and fixed by the lower straps 9.

[0034] A handle 19 is installed on the threaded rod 15. Turning the handle 19 will cause the threaded rod 15 to rotate.

[0035] When using this sports medicine knee joint care device, first place the upper guard plate 6 on the patient's thigh and secure it with the upper strap 7. Simultaneously, place the lower guard plate 8 on the patient's calf and secure it with the lower strap 9. When the patient is standing, rotate the handle 19 in the opposite direction to rotate the threaded rod 15. The threaded rod 15 rotates within the threaded sleeve 14 and moves outward, pulling the insert rod 17 out of the tooth groove on the gear 10 via the round rod 16. At this time, the spring 18 is compressed. As the patient moves, the movable plate 12 on the lower fixator 2 drives the rotating shaft 11 and the gear 10 to move within the rear end cover 4. 12 moves along the movable groove 13 of the rear cover 4. When the patient sits down, as the knee joint bends, the threaded rod 15 is rotated in the threaded sleeve 14 by rotating forward. The rod 16 causes the insert rod 17 to be inserted into the tooth groove of the gear 10, positioning the upper fixator 1 and the lower fixator 2. This allows the knee joint, which is suspended in front of the seat, to be supported independently, making it suitable for sitting and protecting the knee joint. The front cover 5 can also be removed to open the rear cover 4, facilitating maintenance and repair of the internal structural parts of the rear cover 4. Conversely, the locking block 20 on the front cover 5 is inserted into the locking groove 21 on the rear cover 4, so that the front cover 5 seals the rear cover 4.
