The top of the spring 2 14 is respectively connected to the bottom of the lower movable connecting plate 8 and the upper movable connecting plate 8. The top of the upper movable connecting plate 8 is fixedly connected to the fixed rod 10. The top of the fixed rod 10 is provided with a sliding groove 2. The sliding groove 2 is slidably connected to the telescopic rod 11. The top of the fixed rod 10 is fixedly connected with a spring 12 sleeved on the outside of the telescopic rod 11.

The contact portion of the telescopic rod 11 and the fixed rod 10 is the contact portion of the telescopic rod 2 15 and the fixed cylinder 13. Both are provided with damping fluid. When the elevator is connected to the device (the connection method is the existing technology and will not be described in detail here), the damping fluid can effectively reduce the self-vibration generated by the spring 12 and the spring 2 14. Reducing the frequency of the self-vibration can effectively improve the shock absorption performance of the spring 12 and the spring 2 14. When an earthquake occurs, the elevator shaft wall 1, the guide rail 2, and the elevator will vibrate. At this time, the movable plate 4 will move vertically along the sliding groove 1.
