The invention discloses a self-resetting anti-bent support based on a belleville spring. Under small displacement, namely under the small shocking effect, when a main body structure is in an elastic state, energy can be consumed through friction among all discs and between the discs and intermediate clapboards. In addition, self-resetting after the self-resetting anti-bent support is shocked can be achieved, residual deformation of a structure is reduced, and after being shocked, the self-resetting anti-bent support can continuously work after appropriate maintenance, and an original supporting component does not need to be replaced.
