The utility model provides a durable gun rope. A gun rope cavity is rotationally connected with a coil spring cavity; the gun rope cavity and the coil spring cavity are rotationally connected independently relative to a fixed seat; a connecting shaft sleeve for enabling the gun rope cavity to freely rotate on the fixed seat is arranged on the outer side, close to the fixed seat, of the gun rope cavity; the center of a rotating shaft is connected with a center connecting shaft for enabling the coil spring cavity to freely rotate on the fixed seat in a penetrating manner; the outer side of the center connecting shaft is sleeved by the rotating shaft; and the outer side of the rotating shaft is sleeved by the connecting shaft sleeve. The durable gun rope is capable of alleviating the damage to the gun rope caused by non-horizontal tension, and simultaneously alleviating friction damage between the gun rope and corresponding component, and the service life is prolonged under the condition of ensuring smooth use.
