Automatic traction device for femoral fracture setting operation

The invention discloses an automatic traction device for a femoral fracture setting operation. A supporting frame has a triangular structure and is used for supporting the lower limbs of a patient toform and keep a leg bending state; the supporting frame comprises a supporting bottom face arranged horizontally, a thigh bearing face and a shank bearing face, wherein the thigh bearing face and theshank bearing face are arranged at the two ends of the supporting bottom face oppositely; the ends of every two adjacent faces are hinged; and the lengths of all the faces can be adjusted and locked through an edge adjusting mechanism. Two thighbone kirschner wire mounting positions are arranged in parallel at an interval and each thighbone kirschner wire mounting position is provided with two thighbone kirschner wire mounting structures arranged on the two sides of the thigh bearing surface respectively. The automatic traction device is stable in operation, the operation difficulty can be reduced, and the broken bone
