A fishtail swing structure and a bionic fish device.The fishtail swing structure comprises a rack, a driving assembly, a first-order rod, a second-order rod and a tail fin, the driving assembly comprises a motor, a driven driving dial, a sliding guide rod fixedly connected with the rack and a driven sliding block arranged on the sliding guide rod in a sleeving mode, and the driven sliding block is concavely provided with a driven sliding groove facing the driving dial; a shifting block slidably connected to the driven sliding groove is arranged on the surface of the driving shifting disc in a protruding mode, a first-order sliding groove is formed in the front section of the first-order rod in a concave mode, a protruding block is correspondingly arranged on the surface of the driven sliding block in a protruding mode, the middle section of the first-order rod is hinged to a positioning shaft fixedly connected to the machine frame, and the protruding block is slidably connected with the first-order sliding groove. The front section of the second-order rod is concavely provided with a second-order sliding groove in sliding fit with a limiting rod relative to the limiting rod extending out of the rack, the middle section of the second-order rod is hinged to the rear section of the first-order rod, and the rear section of the second-order rod is hinged to the head end of the tail fin and connected with the head end of the tail fin through an elastic piece. And the bionic effect is good.
