Provided is a hydraulic pull rod used for an operation vehicle under a mine, relating to an operation vehicle under the mine. The hydraulic pull rod comprises a rod body which is a hollow rod body. One end of the rod body is provided with a deflecting plate, on which a first deflecting rod is connected. The other end of the rod body is provided with an opening. A telescopic rod is arranged in the hollow rod body and stretches out of the other end of the rod body. The front end of the telescopic rod is connected with a second deflecting rod. The rear end of the telescopic rod is provided with a top plate. Closed space is formed between the top plate and the deflecting plate. A water inlet pipe is connected above the closed space at one end of the rod body and connected with a hydraulic cylinder. One side of the deflecting plate is provided with an inserting rod. One side of the top plate is provided with a column which is a hollow column. The inserting rod is inserted into the hollow column and capable of sliding in the hollow column. The hydraulic pull rod used for the operation vehicle under the mine has following beneficial effects: the hydraulic pull rod is simple in structure and reasonable in design; the hydraulic rod is utilized for replacing a straight pull rod to apply to the small vehicle under the mine such that rotation force of a steering wheel is decreased and the pull rod is shortened; and the hydraulic pull rod is well installed on the vehicle in order to reduce space under the mine.
