The traction rod comprises a composite rod body, metal end heads are arranged at the two ends of the composite rod body, and longitudinal winding layers formed by winding fibers in the axis direction of the composite rod body and the annular direction of metal connectors are arranged on the peripheries of the composite rod body and the metal end heads. The outer surface of the longitudinal winding layer corresponding to the connecting position of the composite material rod body, the metal connector and the composite material rod body is provided with an annular winding layer formed by winding in the annular direction of the composite material rod body. The traction rod is light in weight, good in fatigue resistance, good in pressure-bearing and tension-bearing performance and high in reliability.
