The upper surface of the longitudinal beam of the second-class chassis 1 is connected to the bottom of the sub-frame 2. The mounting frame 3 comprises a fixed frame 31 and a rotating frame 33. The front end of the fixed frame 31 is connected to the end of the sub-frame 2 away from the second-class chassis 1, and the rear end of the fixed frame 31 is rotatably connected to the rotating frame 33. A lifting cylinder 35 is arranged at the rear end of the fixed frame 31, and the end of the lifting cylinder 35 away from the fixed frame 31 is hinged to the rotating frame 33; a safety seat 5 that can be pinned to the fixed frame 31 is arranged above the front end of the rotating frame 33, and an anti-collision buffer bag 4 is arranged at the rear end of the rotating frame 33.
