The inner part of the liquid capsule 25 is saturated in the initial state. The side of the liquid capsule 25 is fixedly connected with the hydraulic cylinder 26.

The bottom of the hydraulic rod 27 is fixedly connected to the inner part of the hydraulic cylinder 26 by a spring, and the spring is in a relaxed state in the initial state. This design enables the spring to drive the hydraulic rod 27 back to the initial position in the initial state. The front of the hydraulic cylinder 26 is rotatably connected with the rotating wheel 28 One side of the rotating wheel 28 is rotatably connected to a vertical rod 1 29, the other side of the rotating wheel 28 is rotatably connected to a vertical rod 210, the top of the vertical rod 1 29 is rotatably connected to a pulley 1 211, the top of the vertical rod 210 is rotatably connected to a pulley 212, the front of the hydraulic rod 27 is rotatably connected to a small rotating wheel 213, one side of the small rotating wheel 213 is rotatably connected to a small vertical rod 1 214, the other side of the small rotating wheel 213 is rotatably connected to a small vertical rod 215, the small vertical rod 1 214 and the small vertical rod 215 are fixedly connected to each other by a spring sheet, and the spring sheet is initially in a relaxed state. This design consumes more impact force when the small vertical rod 1 214 and the small vertical rod 215 rotate.
