The trailer is hung in the trunk or car toolbox. Under normal circumstances, a car can run on the power output by its own engine, but in some emergency situations, such as the engine is broken and the car can't run in a swamp, the owner must need the power of other vehicles to help him run.

Attention should be paid to the use of trailer hooks

1, a car owner was looking for the front trailer hook of the vehicle. Because he couldn't find it at the moment, he tied the traction rope to the front bumper of the vehicle, which was very dangerous.

2. When a car with a weight of more than one ton is pulled by a thin bumper, if the bumper is of good quality, it will cause serious deformation. If the bumper is of poor quality, the whole front face of the vehicle may be torn open.
