[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The use of cable traction devices and winches for mechanical laying can increase the safety of construction and reduce the possible danger of construction workers' movements when working in narrow spaces. The winch replaces manual pulling, mechanized operation, saves labor and reduces costs.

[0013] 2. A sliding cable bracket is set in the cable trench wall to reduce the waste of angle steel bracket materials in traditional bracket methods and the damage to the cable outer skin caused by the cable sliding on the angle steel, saving costs and reducing the friction resistance of the cable during laying, which can save time and effort to complete automatic laying.

[0014] 3. Multiple cables can be laid together, greatly improving the efficiency of cable laying construction and greatly reducing construction period and labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
