The invention belongs to the technical field of plastic processing, and in particular relates to a core rod for a turret of an injection blow molding machine and a use method thereof. The invention provides a core rod for a turret of an injection blow molding machine, comprising: a turret; at least one connecting component detachably arranged on the side wall of the turret; and at least one injection core rod matched with the connecting component. Wherein, if the injection core rod is long, the inner sleeve of the connecting component contracts inwardly, and the inner and outer layers of the connecting component are suitable for limiting the injection core rod; if the injection core rod is short, the inner sleeve of the connecting component extends outwardly, and the inner sleeve is suitable for being inserted into the end of the injection core rod. Through the arrangement of the connecting component, injection core rods of different lengths can be adapted to the turret, and the stability of the injection core rod fixed on the side wall of the turret is improved.
