Convenient and easy to operate.

In order to solve the above-mentioned technical problems, a technical solution adopted by the utility model is to provide a limb tractor, including: a fixing belt, a bearing seat and a pulling device; there are two fixing belts, and the two fixing belts are respectively front belt and rear fixing belt; there are four bearing seats, and the four bearing seats include two front bearing seats and two rear bearing seats; two front bearing seats are fixed on the front fixing belt, and two front bearing seats Respectively close to the two ends of the front fixing belt, the position corresponding to the two front bearing seats on the rear fixing belt is fixed with two rear bearing seats, and the two rear bearing seats are arranged opposite to the two front bearing seats; the traction device has Two, the two ends of the traction device are respectively fixed on the front bearing seat and the rear bearing seat; the traction device includes an inner support rod and an outer support rod, the front end of the outer support rod is fixed on the front bearing seat, and the rear The end has a threaded hole, and the outer wall of the inner support rod near the front end is provided with an external thread that matches the threaded hole. Rotate on the rear bearing seat; rotate the inner support rod, and the outer support rod moves along the axis direction of the inner support rod.

Preferably, the front end of the outer support rod is fixed on the front bearing seat by a locking screw, the axis of the locking screw is perpendicular to the axis of the outer support rod; the rear end of the inner support rod is fixed with a handle.

Preferably, the fixing belt is a belt, and round holes in the length direction of the belt are distributed on the belt. One end of the belt is provided with a belt buckle, and the belt buckle can be stuck on the round holes.

The beneficial effects of the utility model are: the utility model can effectively pull the limbs to reset, and play the role of reset and supporting fractures.
