[0026] Working principle of this utility model:
[0027] The device is mainly used to control the pressure of the two spaces inside the active cylinder 200 through the pressurization and pressure relief of the active cylinder pressure valve 203 and the loading cylinder pressure relief valve 304, thereby driving the active valve 205 and the active rod 201 to slide in the active cylinder 200, so as to achieve the effect of controlling the movement of the U-shaped connecting frame 202.

The movable loading rod 301 is controlled by the loading cylinder movable valve 305, the loading cylinder pressurizing valve 303 and the loading cylinder pressure relief valve 304. The front end bracket 101 uses the first circular sleeve 405 and the second circular sleeve 406 to fix the rotating bearing 408 on the movable shaft 400, thereby ensuring the stable rotation of the movable shaft 400. The rotating movable shaft 400 drives the eccentric wheel 401 to rotate, thereby achieving the effect of simulating inertia by using the eccentric wheel 401. The second circular sleeve 406 and the connecting shaft 404 are used to drive the movable shaft 400 to rotate, and the position of the eccentric wheel 401 can be adjusted to create different inertias.
