1. The structure of the utility model is simple and durable. By setting the traction rope and the traction machine, the traction machine realizes the laying of the cable by retracting the traction rope. The traction machine can be fixed at one point without moving along the cable laying path, avoiding damage to cultivated land or crops. The problem is that by setting the support, the cable is separated from the ground, which greatly reduces the risk of cable wear and tear, and reduces the risk of leakage and cable explosion caused by the rupture of the cable during use.

2. By setting an arc-shaped groove in the center of the side of the guide wheel, it provides guidance and limit for the movement of the traction rope and the cable, and ensures the smooth progress of the cable laying work.

3. By setting the fixing nails and stepping the fixing nails into the ground, the support can be easily fixed.
