The surface of the spring-shaped metal sheath 104 is also coated with a layer of anti-oxidation paint, which can prevent metal oxidation and corrosion. The spring-like metal sheath 104 and the metal shaping rod 105 are made of pure copper, which has good ductility and is therefore suitable for shaping. Those skilled in the art can also use other metals for implementation according to cost needs. Preferably, the metal shaping rod 105 can be realized by using a pure copper metal rod with a diameter of 2 mm, which is relatively easy to bend and may provide strong shaping ability. The use of the spring-shaped metal sheath 104 on the outside of the network cable in conjunction with the internal metal shaping rod 105 can make the shape of the network cable more stable.
