[0002] Existing traffic facilities include street lights, traffic lights, and road traffic signs, all of which use fixed rods to fix the equipment on both sides of the road for use. However, there are many traffic accidents in traffic roads. For example, a car driver is distracted and hits a traffic facility, causing the vertical rod at the bottom of the traffic facility to bend and break, which cannot effectively protect the traffic facility further, and at the same time cannot reduce the damage degree of the car, resulting in large losses for both municipal maintenance and car maintenance.

[0003] Chinese Patent Document Publication No. CN 220284685 U discloses a traffic facility safety anti-collision device, including a traffic facility rod and a solar panel.

A return spring column is arranged inside. An LED lamp ring is arranged on one side of the central column. One end of a chain is provided with a magnet type connector. A magnetic card inductor is arranged on one side surface of the magnet type connector. It can effectively protect the traffic equipment. When a traffic accident occurs, it can effectively reduce the damage of the traffic facility and the vehicle, reduce the harm coefficient of the traffic accident, minimize the impact damage of the traffic facility and the vehicle, provide convenience for later maintenance, and at the same time can add color when protecting the traffic facility, improving the overall aesthetic degree.
