This utility model provides a leg fracture traction device, relating to the field of leg fracture traction devices. The utility model includes a base plate, with a traction device mounted on one side of the base plate. By setting up a traction mechanism, when performing traction treatment on a fracture patient, the injured leg can be fixed to a slide and a fixation frame using a fixing component. Then, according to treatment needs, a self-locking motor is activated to drive a threaded rod to rotate, thereby causing a screw hole block to slide to one end on the inner wall of the base plate. Then, under the pull of a first telescopic rod and a first spring, the slide can move to one end within the inner wall of the base plate. The first spring and the first telescopic rod act as a buffer between the slide and the screw hole frame, preventing excessive traction caused by the screw hole block moving too quickly. This allows the slide to provide flexible traction according to actual usage during the traction process, avoiding secondary injury and improving treatment efficiency.
