Self-resetting energy consumption support

A self-resetting energy consumption support comprises an inner constraint tube, an outer constraint tube, a wide ear plate, an anti-shear rivet, lead sand, an outer constraint tube ear plate, a baffle, fixed end plates, a rope, a clamp and an anchor plate. At a plant, the wide ear plate, the anti-shear rivet and the inner constraint tube are welded and spliced at first; the outer constraint tube ear plate, the baffle and the outer constraint tube are welded and spliced; the inner constraint tube is disposed in the outer constraint tube; the outer constraint tube is then welded and connected; then, the rope of the self-resetting system is inserted into the inner constraint tube and then passes through openings of the fixed end plates; prestress is applied to tightly press the fixed end plates on two ends of the outer constraint tube; the rope is tensioned and anchored on the anchor plate by the clamp; and finally, the lead sand is poured in via a pouring hole so as to form a lead center, and then splicing is c
