A shear spring for a flip-flow screen belongs to the technical field of vibrating screen equipment and is used for preventing a rubber block from being separated from a bonded steel plate. According to the technical scheme, an upper shearing spring steel plate is bonded with the upper surface of a rubber block, a lower shearing spring steel plate is bonded with the lower surface of the rubber block, a plurality of embedding holes are evenly distributed in the plate face of the upper shearing spring steel plate and the plate face of the lower shearing spring steel plate, and a plurality of protrusions are evenly distributed on the upper surface and the lower surface of the rubber block. The positions and the shapes of the protrusions on the upper surface and the lower surface of the rubber block correspond to the positions and the shapes of the embedding holes in the plate faces of the shear spring upper steel plate and the shear spring lower steel plate respectively, the protrusions of the rubber block are em
