[0018] In this embodiment: the knee pad 1 is used to support and position the patient's knee. At this time, the knee pad 1 has a certain curvature, so that it can support the patient's knee. When the lower limbs are tractioned, the lower limbs need to maintain abduction neutral position. Due to the duration of traction and the effect of gravity, it is not easy to maintain the functional position of the lower limbs and it is easy to form heel pressure sores. At this time, the knee pad 1 can be used to assist in supporting the knee and support the knee joint to a flexion position of 5 degrees to 10 degrees, reducing the burden on the patient's lower limbs. At the same time, the foot pad 2 is used to support the patient's foot. The foot pad 2 uses a soft, lightweight and breathable material to reduce the risk of pressure sores on the patient's feet. At the same time, the foot pad 2 can be used to support the patient's feet. The footrest 2 is used to support and limit the patient's foot, so that after limiting the position of the patient's foot, the ankle joint can maintain a neutral position, without dorsiflexion or plantar flexion, without eversion or inversion, and the plantar plane does not deflect in any direction, so that the knee pad 1 and the foot pad 2 are used together to ensure the traction of the lower limbs. When using the device to support the patient's knees and ankles, due to the different leg lengths of different patients, in order to prevent the support height of the knee pad 1 from being fixed, it is inconvenient to adjust the knee height according to the patient's own lower limb length. At this time, the support plate 3 installed at the bottom of the knee pad 1 can be used to support the knee pad 1. At the same time, the top height of the knee pad 1 is controlled by the frame plate 4 installed above the support plate 3. The support is such that the slide groove 31 opened on the top of the support plate 3 can be used to install the slider 33, and the slider 33 slides on the inner wall of the slide groove 31 so that it can adjust its position on the inner wall of the slide groove 31 by sliding. When the slider 33 is adjusted, the mounting plate 34 fixedly connected to the slider 33 is adjusted synchronously, and the spacing between the inclined plates 35 fixedly connected to the top of the mounting plate 34 can be adjusted. Therefore, the top plate 41 fixedly connected between the frame plates 4 is used to install the support block 42, and the support block 42 is supported by the inclined plates 35. When the spacing between the inclined plates 35 continues to increase, the height of the top plate 41 can be lowered, and when the spacing between the inclined plates 35 is contracted, the top plate 41 can be lowered. The support height of the support block 42 is increased, so that the support height of the frame plate 4 for the knee pad 1 can be changed, and the telescopic plates 43 slidingly connected on both sides of the support block 42 are hinged to the side plates 44, and the other end of the side plates 44 is hinged to the hinge plate 46, so that when the telescopic plates 43 and the support block 42 are synchronously displaced up and down, the angle of the side plates 44 can be adjusted upward. At the same time, one end of the side plate 44 is limited on the hinge plate 46, and the telescopic plates 43 can adjust their own length to make way for the position change of one end of the side plate 44, so that the frame plate 4 supports both sides of the knee pad 1 and the patient's lower limbs, so that the device can be adjusted accordingly according to the patient's lower limbs to ensure that the patient's lower limbs remain in a functional position during traction.

[0020] The inner wall of the foot pad 2 is slidably connected to two splints 21 for limiting the patient's feet, and a protective pad 22 is fixedly connected to one side of the splint 21; the splints 21 slidably connected to the inner wall of the foot pad 2 can be slidably adjusted to adjust the distance between them, so that the protective pad 22 fixedly connected to one side of the splint 21 can support and protect both sides of the patient's feet, preventing the patient's feet from turning inward and outward.
[0021] A partition plate 311 is fixedly connected to the inner wall of the slide groove 31, and a screw rod 32 is rotatably connected to the partition plate 311. The screw rod 32 is threadedly connected to the slider 33. One end of the screw rod 32 passes through the support plate 3, and the other end of the screw rod 32 is fixedly connected to the rotating block 321; the partition plate 311 fixedly connected to the inner wall of the slide groove 31 is used to install the screw rod 32, so that the screw rod 32 can adjust the position of the slider 33 slidably connected to the inner wall of the slide groove 31 by rotation, and the rotating block 321 is used to facilitate the rotation of the screw rod 32, so that the slider 33 drives the mounting plate 34 and the inclined plate 35 to adjust the position, so that it can adjust the support height of the frame plate 4.
