[0010] In one possible design, the adjusting mechanism includes two second threaded rods and two connecting blocks. The top of the fixed base has two grooves. One end of each of the two second threaded rods is rotatably connected to the inner wall of one side of the two grooves. The bottoms of the two connecting blocks are slidably connected to the inner wall of the bottom of the two grooves. The connecting blocks have second threaded holes. The second threaded rods are threadedly connected to the second threaded holes. The other end of each second threaded rod passes through one side of the fixed base. One end of each second threaded rod is fixedly equipped with a handwheel to facilitate rotation of the second threaded rod. The top of the connecting block is fixedly connected to the bottom of the concave plate.
[0011] In one possible design, the arm exercise mechanism includes two tension springs and two grips. A first fixed ring is welded to the side of each of the two legs that are far apart from each other. A first movable ring and a second movable ring are welded to the two ends of the tension springs, respectively. The first movable ring is fitted inside the first fixed ring, and the second movable ring is fitted inside the second fixed ring. The grips are T-shaped, and the bottom ends of the two grips are welded to one side of the two second fixed rings, respectively.
[0012] In one possible design, fixing blocks are fixedly installed on both sides of the seat, and a magnet for magnetically fixing a second fixing ring is fixedly installed on one side of each fixing block. The second fixing ring is made of iron.
[0013] In one possible design, a motor for adjusting the lower leg plate left and right is fixedly installed on the bottom inner wall of the concave plate. A first threaded rod is fixedly installed at the output end of the motor. A moving block is slidably connected to one side inner wall of the concave plate.

When left or right adjustment of the leg plates is needed, the motor is started, causing the first threaded rod to rotate, causing the moving block to slide within the concave plate, thereby adjusting the frame and leg plates. This allows the leg plates to be adjusted left or right to be moved to the patient's lower leg position. The lower leg is then placed on the corresponding leg plate, and the electric push rod is started. The push rod moves the calf plate up and down, providing traction and elevation exercises for the lower leg (the extension and retraction speed and height of the electric push rod can be adjusted via an external controller according to the patient's specific condition and exercise needs). Alternatively, the patient can place their feet on the calf plate, start the motor to rotate the first threaded rod, causing the moving block to slide within the concave plate, thereby moving the frame and calf plate. This allows for flexion and traction exercises of the lower limbs. The motor is a stepper motor, which can rotate forward and backward. For arm strength training, the patient sits in the chair, holds the two handles, and raises their arms to stretch the tension springs, thus exercising their arms. During the exercise, the second fixing ring can be fixed to the fixing block with a magnet for intermittent strength training. This system effectively improves the practicality of exercises for both the lower limbs and arms.
[0017] The beneficial effects of this utility model are as follows:
[0018] In this utility model, the traction exercise device after lower limb fracture surgery, through the adjustment mechanism, rotates the handwheel to make the second threaded rod rotate in the groove, thereby driving the connecting block to slide in the groove, thereby adjusting the position of the concave plate. The movement of the concave plate drives the movement of the frame, electric push rod and lower leg plate, thereby adjusting the distance between the two lower leg plates so that the patient's lower leg can be placed on the two lower leg plates.
[0019] In this utility model, a traction exercise device for postoperative lower limb fracture is described. Through the arm exercise mechanism, the patient sits on a chair, holds two handles with both hands, raises both arms, stretches the tension spring, and performs arm strength exercises.
[0020] In this invention, the distance between the two calf plates can be adjusted by an adjustment mechanism so that the patient's calf can be placed on the two calf plates. The arm exercise mechanism can exercise the patient's arm. By exercising the patient's lower limbs, the patient's arm can also be exercised, effectively improving the practicality.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Example 1
[0028] Reference Figures 1-4 An exercise device includes a base 1, a fixed seat 2, a seat, a concave plate 5, a frame 18, and a calf support 6. The base 1 serves as the support for the entire device, and the fixed seat 2, fixedly mounted on one side of the top of the base 1, is used to mount and support the concave plate 5. The seat consists of a seat plate 4 and two legs 3, placed in a designated position on the base 1 for the patient to sit on. The frame 18 is slidably connected to the top of the concave plate 5, and the calf support 6 is located on the top of the frame 18 for placing the patient's calves for traction exercises. To reduce friction during frame 18 movement, a groove is provided on the top of the concave plate 5, and a slider that cooperates with the groove is fixedly mounted on the bottom of the frame 18.
[0029] A motor 7 is fixedly installed on the bottom inner wall of the concave plate 5, and the output end of the motor 7 is connected to the first threaded rod 9. A movable block 20 is slidably connected to one side inner wall of the concave plate 5, and the movable block 20 has a first threaded hole that mates with the first threaded rod 9. When the motor 7 starts, it drives the first threaded rod 9 to rotate, thereby pushing the movable block 20 to slide within the concave plate 5. An L-shaped plate is fixedly installed on one side of the top of the movable block 20, and one side of the L-shaped plate is fixedly connected to one side of the frame 18. Therefore, the sliding of the movable block 20 will cause the frame 18 and the lower leg plate 6 to adjust left and right.
[0030] An electric push rod 19 is also fixedly installed on the bottom inner wall of the frame 18. The telescopic part of the electric push rod 19 passes through the through hole at the top of the frame 18 and is fixedly connected to the bottom of the calf plate 6. When the electric push rod 19 is activated, it will drive the calf plate 6 to move up and down, thereby realizing the calf raising exercise.
[0031] An adjustment mechanism is mounted on the fixed base 2 to adjust the distance between the two lower leg plates 6. This adjustment mechanism includes two second threaded rods 16 and two connecting blocks. Two grooves 17 are formed on the top of the fixed base 2, and one end of each of the two second threaded rods 16 is rotatably connected to the inner wall of one side of each groove 17. The bottoms of the two connecting blocks are slidably connected to the inner wall of the bottom of each groove 17. A second threaded hole is formed on the connecting block, and the second threaded rod 16 is threadedly connected to the second threaded hole. The other end of each second threaded rod 16 passes through one side of the fixed base 2 and is fixedly mounted with a handwheel 8 for easy rotation. The top of the connecting block is fixedly connected to the bottom of the concave plate 5. Therefore, when the handwheel 8 is rotated, the second threaded rod 16 rotates within the groove 17, thereby pushing the connecting block and the concave plate 5 to slide on the fixed base 2, thus adjusting the distance between the two lower leg plates 6.
[0032] An arm exercise mechanism is installed on a seat to train the patient's arm strength. The mechanism includes two tension springs 10 and two handles 14. A first fixed ring 12 is welded to the opposite side of each of the two support legs 3. A first movable ring 11 and a second movable ring are welded to both ends of the tension springs 10, respectively. The first movable ring 11 is fitted inside the first fixed ring 12, and a second fixed ring 13 is fitted inside the second movable ring. The handles 14 are T-shaped, with their bottom ends welded to one side of each of the two second fixed rings 13. Therefore, when the patient grips the handles 14 and stretches, the tension springs 10 extend and retract, thereby training the arm strength.
[0033] This application is for the field of traction exercise after lower limb fracture surgery, but it can also be used in other fields applicable to this application.
