The utility model discloses a traction device, which belongs to the technical field of hose extrusion processing equipment and comprises a guide mechanism, a support rod and a conveying mechanism, one end of the support rod is connected with the guide mechanism, the support rod penetrates through the conveying mechanism, and the other end of the support rod is connected with an extrusion die. By installing the supporting rods, a traction path is provided for the braid layer, and local accumulation of the braid layer is prevented. Besides, the guide mechanism is arranged on the upstream of the conveying mechanism, and the braid layer is expanded by the aid of the rotating part, so that the problem of large internal stress of the braid layer is solved. The first rotating part and the second rotating part cooperate with the first rotating part and the second rotating part to convey the woven layer, so that the tension of the woven layer is dispersed, the situation that local stress is too large is reduced, a part of force which is borne by the woven layer in an extrusion die and causes rotation is offset, and the stability of the working state of the woven layer and the product uniformity are improved.
