[0038] The upper and lower ends of the connecting rod 1 are respectively rotatably connected to the connecting seat 7. On one side of the inner wall of the rear end of the connecting rod 1 away from the center of the connecting rod 1, first sliding grooves 3 are respectively provided. Threaded connections are respectively arranged on the inner walls of the rear ends of the first sliding grooves 3 with first adjusting threaded rods 4. The front ends of the first adjusting threaded rods 4 are respectively rotatably connected to first fixing blocks 6.

[0051] By turning the first knob 5, the first adjusting screw rod 4 rotates, so that the first fixing block 6 slides inside the first sliding groove 3, and the moving direction of the adjusting frame 13 is restricted by the limiting groove 8.

[0052] Working principle: When using this multifunctional orthopedic traction and body position fixing device, first, according to the limb length of the patient, turn the handle 12 to make the driving adjusting screw rod 11 rotate, and make the support rod 2 slide inside the adjusting frame 13, so that the support rod 2 and the adjusting frame 13 are extended. Secondly, turn the second adjusting screw rod 21 by the second knob 22, so that the second fixing block 23 slides inside the connecting groove 10, so that the second fixing block 23 can fix the handle 12 to prevent the handle 12 from rotating. Subsequently, according to the bending angle of the diseased limb of the patient, make the connecting seat 7 rotate inside the connecting rod 1, so that the angles of the connecting rod 1, the support rod 2 and the adjusting frame 13 fit the bending angle of the diseased limb of the patient. Then, turn the first adjusting screw rod 4 by the first knob 5, so that the first fixing block 6 slides inside the first sliding groove 3, so that the first fixing block 6 can be closely attached to the connecting seat 7, and the angle between the connecting seat 7 and the connecting rod 1 is fixed. Finally, select the corresponding number of the first clamping blocks 15 provided with the second clamping blocks 18 and the first clamping blocks 16 according to the actual number of metal needles set on the diseased limb of the patient, and make the first clamping blocks 15 be clamped on the support rod 2, so that the second clamping blocks 18 and the first clamping blocks 16 stably clamp the metal needles set on the diseased limb of the patient.
