[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires are insulated from each other and are often twisted around a center wire. The entire outside is covered with a highly insulating covering. Cables have the characteristics of being powered inside and insulated outside. Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulating layers, and are used to connect circuits, electrical appliances, etc.

[0003] However, when existing cables are used in corners or turning corners, the inner surface of the cable contacts the corner of the wall. When affected by external forces such as strong winds, the inner surface of the cable will rub against the corner, which can easily cause wear on the outer sheath of the cable, affecting the safe use of the cable and reducing the service life of the cable. In addition, it is difficult to protect the outer surface of the cable. When hit by a sharp object, the outer sheath of the cable is easily damaged, affecting the safe use of the cable and causing unnecessary losses. Utility Model Content

[0027] When the cable body 1 is used at a corner or a turning corner, slide a pair of fixing rings 2 on the surface of the cable body 1.
