[0002] Communication cables are cables for transmitting telephone, telegram, fax documents, television and radio programs, data and other electrical signals. They are composed of one or more pairs of mutually insulated conductors twisted together. Compared with overhead lines, communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and less influence by natural conditions and external interference. In the laying of communication lines, the laying method in urban areas is often to use a traction machine to pull the line while laying it. This method is very fast and convenient.

[0003] However, the existing construction cable protection device cannot adjust the size, which limits the scope of application of the equipment and is not conducive to processing cables of different specifications. It is necessary to equip a separate fixing device for each specification of cable, which increases the company's cost. When the cable is smaller than the fixing device, the cable is not stable enough, which will cause friction between the cable and other parts, easily causing damage to the cable sheath. After searching, it was found that the technical solution provided by the utility model with application number CN201920466792.X also has the above-mentioned problems. Utility Model Content
