[0003] In order to realize the connection of two different types of car hooks and realize the connection of the existing locomotive vehicle and motor train unit or subway vehicle, a transition device is needed to connect the two different types of car hooks. The structural feature of the transition car hook is that one end is connected with the general automatic car hook, and the other end is connected with the close-coupled car hook. Due to the great difference in structure, the manufacturing difficulty is very great. The general structure of the existing transition car hook is the front half of the general automatic car hook, and the close-coupled car hook is made into a whole structure for use. The structure of this transition car hook is widely used in the case of zero or small hook height difference. In the case of large hook height difference, the center of gravity of the transition car hook is concentrated on the side of the close-coupled car hook, resulting in a serious "drooping head" phenomenon of the hook head of the close-coupled car hook. Directly affect the connection efficiency of the transition car hook.

[0004] Therefore, it is necessary to provide a combined transition car hook to solve the problems mentioned in the background. INVENTION CONTENTS
