Narrow-slit cable threading tool

The invention discloses a narrow-slit cable threading tool. The narrow-slit cable threading tool comprises a fixed pipe, one side of the fixed pipe is connected with a bracket, the bracket is connected with a winder, and the winding end of the winder is connected with a steel wire rope. The narrow-slit cable threading tool takes the steel wire rope as a guide wire of a cable, and a detachable rigid guide rod device is additionally arranged at the end portion of the steel wire rope, and can form a guide rod structure by adopting the guide rod to allow an operator to conveniently hold the guiderod by a hand to allow the guide rod to penetrate the protection pipe of the cable, because the guide rod has good rigidity relative to the steel wire rope to more conveniently break through the blocking and the friction in the protection pipe of the cable and avoid that the steel wire rope is easily blocked in the protection pipe of the cable and cannot pass through the protection pipe of the cable so as to improve the w
