In practical application, the filler 22 is made of a buoyancy material, the limiting wire 31 is made of nylon, the buoyancy material can reduce the overall quality of the propeller, the overall positive buoyancy is increased, the limiting wire 31 is made of nylon, electrochemical corrosion caused by contact between different metals is effectively avoided, the diameter of the shell is reduced, materials are saved, and the fluid performance is facilitated.
The present invention is not limited to the above-mentioned embodiments, but is intended to be limited to the following embodiments, and any modifications, equivalents and modifications can be made to the above-mentioned embodiments without departing from the scope of the invention.
