One end of the second pump is fixedly connected to a second hose, and the other end of the second hose extends to the bottom of the counterweight cylinder.
[0010] Preferably, the adjusting mechanism includes a first lead screw fixedly connected between one sides of the two columns. At least two rotating blocks aligned with the moving blocks are threadedly connected to the circumferential side of the first lead screw. Annular grooves are formed on both sides of the rotating block, and a fixed frame is slidably connected to the inner wall of the circumferential side of the annular groove. One end of the fixed frame is fixedly connected to a guiding cylinder aligned with the first hose, and the circumferential side of the first hose is slidably connected to the inner wall of the circumferential side of the guiding cylinder.
[0011] Preferably, at least two scale plates are fixedly connected to the side of the connecting frame. A rotating groove is formed between the top and the bottom of the scale plate, and a rotating frame is slidably connected to the circumferential side of the rotating groove. The circumferential side of the second hose is slidably connected between the top and the bottom of the rotating frame. Scale lines are provided on the top of the scale plate and the top of the rotating frame.
[0012] Preferably, the circumferential side of the counterweight cylinder is slidably connected to the circumferential side of the fixed frame. A moving frame is slidably connected to the circumferential side of the annular groove, and the other end of the moving frame is fixedly connected to the bottom of the moving block. A lifting plate is fixedly connected to the bottom of the column, and a bottom plate is arranged below the lifting plate.
[0013] Preferably, a motor is fixedly connected to the top of the bottom plate.

[0014] Preferably, the protection mechanism includes a fixing belt fixedly connected between the inner walls of both sides of the connecting frame. An elastic belt aligned with the fixing belt is arranged between the inner walls of both sides of the connecting frame. At least two staggered and aligned elastic cords are slidably connected inside the elastic belt, and both ends of the elastic cords are fixedly connected to one side of the connecting frame.
[0015] The beneficial effects of the present invention are as follows: By providing the hollow annular belt, the device is moved near the patient, and the patient's leg is passed through the first soft belt, the second soft belt and the hollow annular belt and fixed by the fixing patch, so that the first soft belt and the second soft belt are respectively fixed on both sides of the patient's knee. This is beneficial for the device to apply tensile force to the patient's leg dispersedly when pulling the patient's leg subsequently, enabling the forces to be evenly conducted on parts such as the patient's thigh and calf, avoiding excessive local stress, which may cause damage or aggravate symptoms due to large compression on tissues such as the knee, affecting the safety during the use of the device. At the same time, it can make the traction force of the device act more precisely on parts such as the femur and tibia. On the premise of achieving correction purposes such as elongation and reduction, it does not interfere with the normal physiological functions of the knee joint. Moreover, the device adjusts the weight of the counterweight cylinder according to the user's weight and the traction force requirements at different positions. The device expands the hollow annular belt, so that when relative displacement is about to occur between the device and the patient's leg, the patient's knee cannot move because it cannot pass through the expanded hollow annular belt, preventing the device from contacting the injured part of the patient's leg and causing the patient to be injured again, affecting the safety and stability during the use of the device.
[0016] By providing the scale disk, before the device is installed on the patient's leg, the connecting frame is moved so that the angle between the scale disk and the second hose is between ten degrees and twenty degrees. This is beneficial for maximizing the traction force along the bone conduction path during the traction correction process, reducing the friction of the joint surface, and providing a better treatment effect when the device treats the patient. At the same time, this angle can also offset part of the contraction force of the adductor muscle group and maintain the reduction stability. At the same time, the device can adjust parameters such as the height of the device according to the patient's body type and treatment needs, improving the applicability of the device.
[0017] By providing the elastic belt, when the device is installed, the patient's foot is inserted into the elastic belt and the patient's foot is vertically abutted against the fixing belt. This is beneficial for making the force line of the patient's lower limb consistent with the traction direction, avoiding stress concentration caused by foot tilt and reducing the risk of traumatic arthritis. When the device accidentally falls off, the patient's sole contacts the elastic belt and drives the elastic belt to move. The elastic belt is contracted by the elastic cord and stuck on the patient's foot, which is beneficial for emergently stopping the movement of the first soft belt, the second soft belt and the hollow annular belt through the elastic belt when the first soft belt, the second soft belt and the hollow annular belt fail and are damaged, preventing the patient from being further injured and improving the safety of the device.

Specific implementation mode
[0020] Example 1, referring to Figure 1-6 , an adjustable traction correction device, including a column 1, a fixing mechanism is arranged on the side surface of the column 1, an adjusting mechanism is arranged on one surface of the column 1, and a protection mechanism is arranged on one surface of the fixing mechanism. The fixing mechanism includes at least two connecting frames 12 arranged on the side surface of the column 1. One end of the connecting frame 12 is fixedly connected with a connecting belt 11. A first soft belt 7 is fixedly connected between the inner walls of the two sides of the connecting belt 11. A second soft belt 9 with a length shorter than the first soft belt 7 is fixedly connected between the inner walls of the two sides of the connecting belt 11 far away from the column 1. Fixed stickers 10 are evenly fixedly connected to the circumferential side surfaces of the first soft belt 7 and the second soft belt 9. One end of the first soft belt 7 and one end of the second soft belt 9 are both fixedly connected with a hollow ring belt 8. A hole groove 30 aligned with the hollow ring belt 8 is opened between the inside of the connecting frame 12 and the inside of the connecting belt 11. An opening 24 is opened between the circumferential side surface of the hole groove 30 and the circumferential side surface of the hollow ring belt 8.
[0021] In the present invention, at least two moving blocks 16 aligned with the connecting frame 12 are evenly arranged above the upright column 1. One side of the upright column 1 is fixedly connected with a limiting plate 17, and the bottom of the limiting plate 17 is slidably connected to the inside of the moving block 16. A chute 18 is formed at the top of the moving block 16, and a first hose 13 is slidably connected to the circumferential side of the chute 18.
[0022] One end of the first hose 13 is fixedly connected to one end of the hole groove 30, and the other end of the first hose 13 is fixedly connected with a counterweight cylinder 2 located below the moving block 16. A first pump 20 is fixedly connected to the inner wall of the top of the counterweight cylinder 2. One end of the first pump 20 is fixedly connected with a first fixed pipe 6, and the other end of the first fixed pipe 6 extends to the bottom of the counterweight cylinder 2. One end of the first hose 13 is fixedly connected to one end of the first pump 20.
[0023] A storage tank is formed inside the upright column 1. A second pump 29 is fixedly connected to the top of the storage tank. One end of the second pump 29 is fixedly connected with a second fixed pipe 28, and the other end of the second fixed pipe 28 extends to the bottom of the storage tank. One end of the second pump 29 is fixedly connected with a second hose 19, and the other end of the second hose 19 extends to the bottom of the counterweight cylinder 2.
[0024] When the present invention is in use: Move the device near the patient. Pass the patient's leg through the first soft belt 7, the second soft belt 9 and the hollow ring belt 8 and fix it with the fixing patch 10, so that the first soft belt 7 and the second soft belt 9 are respectively fixed on both sides of the patient's knee. This is beneficial for the device to disperse the pulling force on the patient's leg when subsequently pulling the patient's leg, enabling the forces to be evenly transmitted to parts such as the patient's thigh and calf, avoiding excessive local stress, which may cause damage to tissues such as the knee or aggravate symptoms, affecting the safety during the use of the device. At the same time, it can make the traction force of the device more accurately act on parts such as the femur and tibia, achieving correction purposes such as elongation and reduction without interfering with the normal physiological functions of the knee joint. Start the second pump 29. The second pump 29 sends liquid into the counterweight cylinder 2 through the second fixed pipe 28 and the second hose 29, so that the weight of the counterweight cylinder 2 is between 10% and 15% of the patient's body weight. This is beneficial for the device to adjust the weight of the counterweight cylinder 2 according to the user's body weight and the traction force requirements at different positions, improving the applicability of the device. Start the first pump 20. The first pump 20 drives part of the liquid to enter the hollow ring belt 8 along the first fixed pipe 6, the first hose 13 and the hole groove 30, causing the hollow ring belt 8 to expand and squeeze on both sides of the patient's knee. This is beneficial to prevent the device from moving when there is a relative displacement between the device and the patient's leg because the patient's knee cannot pass through the expanded hollow ring belt 8, and to prevent the device from coming into contact with the injured part of the patient's leg when the fixing patch 10, the first soft belt 7 and the second soft belt 9 of the device become loose, resulting in the patient being injured again and affecting the safety and stability during the use of the device.

The circumferential side of the first hose 13 is slidably connected to the inner wall of the circumferential side of the guiding cylinder 27.
[0026] In the present invention, at least two scale plates 21 are fixedly connected to the side of the connecting frame 12. A rotating groove 32 is formed between the top and bottom of the scale plate 21. A rotating frame 31 is slidably connected to the circumferential side of the rotating groove 32.

A limiting column 3 is fixedly connected to the top of the bottom plate 5. The other end of the limiting column 3 extends above the lifting plate 4. The circumferential side of the limiting column 3 is slidably connected to the inside of the lifting plate 4.
[0029] When the present invention is used: Before installing the device on the patient's leg, move the connecting frame 12 so that the connecting frame 12 drives the scale disk 21 to abut against the guiding cylinder 27. Rotate the connecting frame 12, and the connecting frame 12 drives the scale disk 21 to rotate so that the angle between the scale disk 21 and the second hose 19 is between ten degrees and twenty degrees, which is beneficial to maximizing the traction force along the bone conduction path during the traction correction process, reducing the joint surface friction, improving the treatment effect provided by the device when treating patients, and at the same time this angle can also offset part of the adductor muscle contraction force and maintain the reduction stability. Rotate the first lead screw 14, the first lead screw 14 drives the movable block 15 to move, the movable block 15 drives the moving frame to move, the moving frame drives the moving block 16 to move, and the moving block 16 drives the first hose 13 to move. Start the motor 25, the motor 25 drives the second lead screw 26 to rotate, and the second lead screw 26 drives the lifting plate 4 and the column 1 to move, which is beneficial to further matching the device with the patient's body type and treatment needs and improving the applicability of the device.
[0030] Example 3, refer to Figure 1-4, An adjustable traction correction device. The protection mechanism includes a fixing belt 33 fixedly connected between the inner walls of both sides of the connecting frame 12.

When the device accidentally falls off, the patient's sole contacts the elastic belt 23 and drives the elastic belt 23 to move. The elastic belt 23 is contracted by the elastic ropes 22 and is stuck on the patient's foot, which is beneficial to urgently stopping the movement of the first soft belt 7, the second soft belt 9, and the hollow ring belt 8 through the elastic belt 23 when the first soft belt 7, the second soft belt 9, and the hollow ring belt 8 fail and are damaged, preventing the patient from being further injured and improving the safety of the device.
