Compared with the prior art, the utility model has the advantages of:

(1) this scheme is through the blade at spliced pole outside fixed connection smooth arc surface, and the reinforcing ride comfort improves and rotates the water conservancy diversion effect, combines the water conservancy diversion recess, effectively reduces the vibrations when using to improve heat dissipation and silence effect.

(2) Through the screw thread water conservancy diversion hole of spliced pole, air current when can the dispersion flabellum rotates reduces the influence to the spliced pole, improves stability in use.

(3) Through screw thread water conservancy diversion hole threaded connection screwed pipe, screwed pipe easy to assemble dismantles, and the filter silver is filtered to the inside removable packing of screwed pipe, filters the silver and filters the air that gets into the toroidal cavity, improves the inside cleanliness factor of toroidal cavity.
