    摘要: The present application provides a coupler telescopic apparatus and a coupler. The coupler telescopic apparatus comprises a housing and a drawbar capable of extending and retracting along the housing, the housing is sleeved outside the drawbar, a limiting block is fixed arranged on an outer side face of the drawbar, a locking ring capable of coming into contact with the limiting block is sleeved inside the housing, and the locking ring is coaxial with the housing and rotatably connected to the housing; a through groove is axially formed on an inner surface of the locking ring, and the through groove correspond to the limiting block in shape, so that the limiting block passes through the through groove when the through groove is aligned with the limiting block, and then an extension of the drawbar is locked by rotating the locking ring to block the limiting block after the extension of the drawbar is completed. The coupler comprises the abovementioned coupler telescopic apparatus. The present application can reduce space occupation and has simple structure.
