The invention provides a pull-retractable connector. The pull-retractable connector comprises a connector body and a connecting rod group consisting of at least two stages of connecting rods in a hinged manner in sequence; the connecting rods at the two ends of the connecting rod group comprise a first-stage connecting rod and a final-stage connecting rod; and the free end of the first-stage connecting rod is used for being connected with a base body while the free end of the final-stage connecting rod is hinged with the connector body. The connector body is connected through the connecting rods, so that the position of the connector body can be kept to a certain degree to avoid the free shaking of the connector body to prevent the connector body from being damaged due to collision with other parts, so that the service life of the connector is prolonged.
