step five: when the hand brake valve (6) is put down, compressed air is supplied to the spring energy storage air chamber (10) from the hand brake air storage cylinder (5) to jack up an energy storage spring in the spring energy storage air chamber (10), so that parking brake of the vehicle A is released, and the vehicle A can be dragged through a trailer; when the hand brake valve (6) is pulled up, the flow of compressed air is blocked, and the parking brake of the vehicle A is realized.
