The invention relates to a one-key release device for the service brake during train coupling rescue, and belongs to the technical field of subway train braking. The device comprises a long-distance release train line and a parking brake train line through the whole train; a parking exerting electromagnetic valve is connected to the parking brake train line in a hanging manner; a long-distance release electromagnetic valve is connected to the long-distance release train line in a hanging manner; the long-distance release train line and the parking brake train line are connected with a power supply of the train through a first coupling relay and a second coupling relay; a three-gear switch arranged in the cab of the train is connected between the first and second coupling relays and the power supply of the train. The one-key release device for the service brake during train coupling rescue has a simple and effective circuit structure, gears are chosen through the switch in the cab to realize braking release, so that compared with the traditional release way, the one-key release device is more convenient.
