[0002] Vehicle rescue refers to a series of emergency services and assistance provided when a car cannot start, breaks down, has an accident or other emergency situations. Vehicle rescue services usually include on-site minor repairs, tire replacement, oil delivery, charging, towing assistance, etc., aiming to ensure the safety of the driver and the normal operation of the vehicle. A vehicle rescue towing device is required during the towing assistance process.

[0003] The Chinese patent with the authorization publication number CN212219813U discloses a vehicle towing device, including a right bracket and a left bracket of a box-type structure, and a crossbeam welded part detachably connected between the right bracket and the left bracket, the right bracket and the left bracket are detachably connected to the vehicle frame, a connecting bracket is fixedly arranged in the middle of the crossbeam welded part, the connecting bracket and the bracket are hinged to form a universal joint structure through a pin shaft and a cotter pin, and the bracket is used to connect the towed vehicle through a tow bar. The vehicle towing device provided by the utility model is not only simple in structure and low in cost, but also easy to install and disassemble, simple and convenient to use, and has a wide range of applications. At the same time, the components and their connections of the utility model are strong and firm, which can effectively ensure the heavy-load towing of the vehicle.

[0004] Although the components and connections of the vehicle towing device mentioned above are strong and firm, and can effectively ensure the heavy-load towing of the vehicle, it is usually necessary to use a rope during the towing process. Due to the complex driving environment, the distance between the faulty vehicle and the towing vehicle is prone to frequent changes. When the distance between the faulty vehicle and the towing vehicle is short, the towing rope between the two will contact the ground. Long-term ground friction can easily damage the towing rope, and it is also easy to cause safety hazards such as vehicle crushing. For this reason, we propose a towing device for vehicle rescue.
