Zusammenfassung:	The invention provides a retracting and putting-down device and a tire burst life support system, and relates to the technical field of tire burst preventing. The retracting and putting-down device comprises a supporting wheel, a connecting assembly and a connecting rod assembly; one end of the connecting assembly is rotatably connected with a rotating shaft of the supporting wheel, and the otherend of the connecting assembly is hinged to a car chassis; and one end of the connecting rod assembly is connected with the connecting assembly, the other end of the connecting rod assembly is used for being connected with the car chassis, and the connecting rod assembly is used for providing the lateral supporting effect, and the supporting wheel is prevented from bearing force and turning back.The retracting and putting-down device is used for being arranged on the position, close to a tire, of the car chassis, when the probability that a car has the tire burst risk is high, the supportingwheel is put down, the conn
