    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.

    摘要： A foldable coupler including a coupler head (1); a rotating arm mechanism (2) with a first arm and a second arm rotatably connected with the first arm; and a folding mechanism (3), including a driving mechanism (31) and a force transfer component (32); the driving mechanism (31) being mounted on the second arm (22), the force transfer component (32) being rotatably mounted on the first arm (21); the driving mechanism (31) being connected with the force transfer component (32) to transfer a driving force to the first arm (21) through the force transfer component (32), so that the first arm (21) and the second arm (22) rotate relative to each other; wherein the first arm (21) is connected to a vehicle body (4), and the second arm (22) is connected to the coupler head (1); or, the first arm (21) is connected to the coupler head (1), and the second arm (22) is connected to the vehicle body (4). A vehicle with the foldable coupler is also disclosed. The foldable coupler not only realizes the automatic folding, the number of driving elements is decreased, and the intermediate control process is simplified greatly.
