Through the joint action of the first piston plate 18, the second piston plate 20 and the spring shock absorber 23, the system can effectively disperse the vibration energy in multiple directions.

[0039] The threaded rod 3 is rotated by the power motor 10 to make the threaded sleeve 4 move linearly along the threaded rod 3, which is guided by the guide rod 12 to ensure the linearity and stability of the movement of the threaded sleeve 4. With the movement of the threaded sleeve 4, it will pull or push the first telescopic rod 2 through the first fixed sleeve 8, thereby adjusting the inclination angle of the anti-seismic support fixed plate 1, and the first spring 9 provides necessary buffering and support in this process.

[0040] When the anti-seismic support fixed plate 1 is subjected to vertical vibration, the second telescopic rod 13 will drive the lifting rod 16 to move up and down, and the first piston plate 18 fixedly connected at the bottom of the lifting rod 16 slides up and down in the annular shell 17, causing the hydraulic oil to flow inside the annular shell 17, generating resistance and achieving the buffering effect in the vertical direction.
