After that, the traction rope 15 is matched and bound with the patient's foot or leg, and the electric telescopic rod 13 starts to pull the traction rope 15 to adjust the traction force, effectively solving the existing problem of easy falling of the counterweight through the weight, and has a flexible pressure adjustment effect. At the same time, by rotating and adjusting the first frame 7, that is, the screw 12 passes through the corresponding circular hole 4 and is threadedly connected to the first frame 7, so as to achieve the first frame 7 and the semi-circular block 11 Fixation, that is, the effect of the first frame 7 and the sliding block 6 is achieved, and finally the position of the pulley 14 is adjusted to change the support position and angle of the traction rope 15. Several circular holes 4 correspond to multiple rotation angles of the first frame 7. The first frame 7 can be rotated to adjust various angles, and the sliding block 6 can also be adjusted in height, which effectively solves the problem that the current device is fixed and has fewer angles and heights, and effectively improves the convenience and adaptability of traction.
