The invention relates to a bionic fishtail propelling device which comprises a shell, side arms, a rack assembly, an incomplete gear, piston sliding blocks, cylinder bodies and a bionic fishtail. The bionic fishtail propelling device is characterized in that the rack assembly is limited in the shell in a sliding mode and comprises a kidney circle structure, the inner walls of the long sides of the circle structure are each provided with a rack, strip-shaped lug structures are arranged at the two ends of the circle structure, the incomplete gear is limited on the shell and is meshed with one rack of the rack assembly, the piston sliding blocks are fixed to the lug structures and limited in the cylinder bodies fixed to the ends of the shell in a sliding mode, the other ends of the piston sliding blocks are fixed by the side arms, and the bionic fishtail is fixed between the left side arm and the right side arm. The rack assembly, the left side arm, the right side arm and the fishtail are driven to achieve reciprocating swing through the meshing transmission of the incomplete gear and the rack assembly, and the bionic fishtail propelling device is simple and compact in structure, good in symmetry and meanwhile capable of driving the fishtail to generate constant speed reciprocating swing.
