Rapidly-adjusted, mounted, pressed and shock-absorbing device

The invention provides a rapid adjustment, installation and compression damping device, and belongs to the field of seismic mitigation and isolation. A first adjusting cushion block is placed in the open end of a sleeve, then an energy-dissipation deformation slotted lining and a wedge-shaped lining are sequentially installed in the sleeve, a hole is formed in the middle of the first adjusting cushion block, and the threaded end of an inner core penetrates through the energy-dissipation deformation slotted lining, the wedge-shaped lining and the first adjusting cushion block through the open end of the sleeve and finally penetrates through the semi-closed end of the sleeve. And the open end of the sleeve is placed into the energy dissipation deformation slotted lining, the wedge-shaped lining and the second adjusting cushion block again, the open end of the sleeve is connected with the sleeve connecting joint through threads, and the threaded end of the inner core is inserted into the inner core connecting jo
