In one state, the roller can reduce the friction resistance between the cable support and the cable, so that the cable can be laid directly along the installation bracket. In another state, the roller can increase the friction resistance between the cable support and the cable, so that the contact between the laid cable and the installation bracket is more stable, and the displacement between the two is prevented, which may cause the cable to fall off, thereby achieving the effect of one thing for multiple uses, and shortening the cable laying cycle compared with the traditional method of laying first and then laying cables.
