When the outer tube 16 moves, the movement limit of the outer tube 16 is controlled by the position of the second bolt 19, so that the phenomenon that the self-resetting energy dissipation support 10 cannot be adjusted to the swing column 8 due to the fact that the prestress component 14 is seriously deformed and cannot be recovered when an earthquake stops is avoided, and the overall stability of the upright frame structure b during vibration is ensured.
