[0002] With the rapid development of the economy and the popularization of electricity consumption, the scope of cable laying is becoming more and more extensive. As long as cables are laid, cable trays must be used. Therefore, cable trays are widely used in petroleum, chemical, electric power, light industry, telecommunications and other industries. They are mainly used for the laying of overhead power cables, lighting cables, control cables and telecommunications cables.

[0003] Current cable trays are generally fixed-length sections. However, during the actual installation of the cable trays, it is often necessary to fine-tune the cable trays. In this case, the manufacturer must be commissioned to customize or modify the cable trays, which increases costs and may delay work hours and reduce applicability. Utility Model Content
