REPAIR TOOL FOR WIRE THREADING AND DRAWING HEAD

WIPO Patent Application WO/2022/104674

A1

A repair tool for a wire threading and drawing head serves as a repair tool for forming a threading and drawing wire for an electric wire by means of pressing and extruding. The repair tool comprises a first gripping part, a second gripping part opposite the first gripping part, and two retaining bolts respectively for the first gripping part and the second gripping part to synchronously move closer to each other. A first half screw hole and a second half screw hole protrude from opposite ends of the first gripping part and the second gripping part, such that the first half screw hole of the first gripping part and the second half screw hole of the second gripping part are moved closer to each other to form a complete screw hole. By means of the positive or negative rotation of the repair tool, the threading and drawing wire for the electric wire is pressed and extruded to form an outer thread portion to increase a thread area. A surface of the outer thread portion is coated with an instantly-drying adhesive and rotated into a drawing head with inner threads, such that the threading and drawing wire for the electric wire and the drawing head fit together more closely, and the tensile strength is increased.
