When used, the user can quickly connect to the oil brake system or the air brake system according to the driving system of the driving vehicle. The trailer is equipped with both an oil brake system and an air brake system, which can effectively solve the problem of fast switching connection and fast braking of the trailer. When there are multiple driving vehicles with different driving systems, the connection can be switched arbitrarily, while avoiding the waste of resources. The long-ventilation air brake can effectively avoid the problem of slipping on a slope.
