The invention relates to a bionic fluctuating long fin underwater propulsor which comprises an upper half drum, a lower half drum, a seal ring, a screw hole, an inflating valve core, a waterproof plug, a first bevel gear, a plurality of fin strips, a long fin, a control circuit board, a first steering gear, a second steering gear, a pressing strip, a first bearing block, a balancing weight, a screw rod, a screw hole, a battery module and a multichannel first steering gear output structure, wherein the multichannel first steering gear output structure is composed of a long shaft, a fin strip base, a second bearing block, a shaft sleeve, a polytetrafluoroethylene ring, a Glyd ring, a ball bearing and a second bevel gear. The upper half drum, the lower half drum and the seal ring are connected and pressed to form a sealed cavity, the long fin is arranged on the lower portion of a cylindrical cavity, the long fin is provided with the fin strips, and the fin strips are equidistantly distributed on the surface of the long fin. Each fin strip is connected with the first steering gear through the first bevel gear and the second bevel gear to be independently driven, the surface of the long fin is made of a flexible film made of a latex material, and the long fin can be driven by the fin strips to achieve multiple waveforms of sine or other types and have the effect with water to generate stable propulsive force.
