The utility model discloses a cable conduit tackle which comprises a sleeve. The sleeve is formed by hinging two semiarc plates. The end portion of the sleeve is provided with rollers and a sleeve opening and closing adjustment device for pushing the two semiarc plates to rotate around an articulated shaft. According to the utility model, the sleeve is disposed in an exit of a cable conduit, the two semiarc plates can be opened around the articulated shaft through the sleeve opening and closing adjustment device, and the sleeve can be fixed in the exit of the cable conduit; and in the pulling process of a cable, the cable contacts the rollers so that the sliding friction between the cable and the mouth of the cable conduit is changed into rolling friction between the cable and the rollers, the sheath of the cable can be prevented from being broken due to friction and the pulling force of the cable can be reduced.
