Described stiffening ring comprises and is multiplely connected to described trunk portion outside successively obliquely respectively and is surrounded on the connecting sheet of described axis, and multiple stiffening rib be connected between two between adjacent described connecting sheet.
Described blade is connected between described connecting sheet and described ring frame.
Described ring frame comprises a frame body, from described frame body apical margin toward sunken inside and around the reentrant part of described axis, and one is protruded outward by described frame body root edge and can be snapped in the bump in the female portion.
Each blade comprises a leading edge and a trailing edge respectively, definition one is by one first straight line in described leading edge and described trailing edge, and one perpendicular to the second straight line of described first straight line, described second straight line angle crossing with described both axis is an angle windward, and described angle is windward between 22 °-26 °.
The beneficial effect of described technological scheme of the present utility model is as follows:
One, be connected to the outer end of described blade by described ring frame, and make described blade not yielding, the generation of shaking phenomenon can be avoided, and then stability when reducing noise and promote running.
Two, by the design of described stiffening ring, allow the structural strength of described blade increase, significantly can promote working life.
Three, the design in the female portion can be placed in by the described bump of described ring frame, conveniently can carry out the carrying work after mutual storehouse and storehouse, have convenience.
