The working principle is as follows: when the earthquake action occurs, multidirectional acting force can be generated, and energy dissipation and shock absorption are performed under different conditions.
When acting force in the horizontal direction occurs, the four metal dampers 6 perform energy dissipation and shock absorption under the rotation supporting action of the first rotating seat 5 and the second rotating seat 7.
When vertical acting force occurs, the plate has acting force on the building direction, the outer sleeve 28 is pulled to slide up and down along the middle sliding assembly 29, and because the third pressure spring 30 is arranged between the middle sliding assembly 29 and the limiting sliding ring 33, when the outer sleeve 28 moves down, energy dissipation and shock absorption are realized through the third pressure spring 30, and the limiting sliding ring 33 is pulled to move synchronously. Because the direction conversion assembly 8 is connected to the limiting sliding ring 33, and the direction conversion assembly 8 is connected to the metal dampers 6 through the second rotating base 7, the metal dampers 6 can be pulled by the up-and-down movement of the limiting sliding ring 33, and the four metal dampers 6 perform energy dissipation and shock absorption under the rotation supporting effect of the first rotating base 5 and the second rotating base 7.

When a twisting acting force occurs, the rotation of the second mounting plate 3 drives the outer sleeve 28 to rotate, and the middle sliding assembly 29 is synchronously twisted as the outer sleeve 28 and the middle sliding assembly 29 are limited by the third limiting sliding groove 38 and the second limiting sliding strip 41; since the limiting sliding ring 33 and the middle sliding assembly 29 are limited by the second limiting sliding groove 36 and the second limiting sliding bar 41, the limiting sliding ring 33 is synchronously twisted to pull the third rotating member 12 to be twisted. Since the sliding rod main body 13 of the sliding rod 9 is connected with the first mounting plate 1 through the vertical shock absorption sliding unit 17, the T-shaped sliding part 19 of the sliding seat 18 on the vertical shock absorption sliding unit 17 slides in the limit sliding groove 34 of the first mounting plate 1 in a limit manner, the first linkage rotating rod 10 and the second linkage rotating rod 11 pull the sliding rod 9 to perform a sliding action, and the four metal dampers 6 perform energy dissipation and shock absorption under the rotation supporting action of the first rotating seat 5 and the second rotating seat 7. The middle sliding component 29 will drive the fixing disc 43 to act synchronously when twisting, and drive the outer damping spring 31 and the inner damping spring 32 to twist, because the directions of the outer damping spring 31 and the inner damping spring 32 are opposite, one is compressed, the other is elongated, and the outer damping spring 31 and the inner damping spring 32 assist in energy dissipation and damping.
During vibration, the multiple acting forces are superposed and then decomposed, and mainly four metal dampers 6 perform energy dissipation and shock absorption; secondly, the vertical damping sliding unit 17 and the third pressure spring 30 as well as the outer damping spring 31 and the inner damping spring 32 are superposed for energy-dissipating damping.
