Embodiment

Describe mode of execution of the present utility model in detail below in conjunction with accompanying drawing.

As Fig. 1 stereogram of the present utility model, Fig. 2 three-dimensional exploded view of the present utility model, Fig. 3 partial exploded view of the present utility model, shown in Fig. 4 side plan view of the present utility model and Fig. 5 part sectioned view of the present utility model, swingable energy-conservation biparting blade fan structure of the present utility model comprises: a support unit 1, one driver element 2 and two blade units 3, wherein support unit 1 has the vertical rod 12 that a base 11 and is combined in base 11 central authorities, driver element 2 has a motor 21 that is mounted in the support unit vertical rod, one is incorporated into the yaw device 22 on the motor 21, an and jacket 23 that covers at this motor 21 and yaw device 22 outsides, this motor 21 has a rotating shaft that runs through 211, this rotating shaft 211 has one first end 2111 and one second end 2112, these yaw device 22 downsides are provided with a connecting rod 221, connecting rod 221 articulates with the vertical rod 12 of support unit 1, yaw device 22 end faces are provided with a controlling rod 222, it is (not shown in the figures that inside is provided with the deceleration wheels, be known technology, do not add to give unnecessary details at this), driving driver elements 2 by this yaw device 22 oscillates about automatically, these yaw device 22 back sides are provided with a fixed base 223 and and are mounted on positioning disk 224 on the fixed base 223 in lock knot mode, these fixed base 223 central authorities have a perforation 2231, these positioning disk 224 central authorities are consolidated with an axle sleeve 2241, this perforation 2231 and this axle sleeve 2241 wear for rotating shaft 211 second ends 2112, and the axle sleeve 2241 by this positioning disk 224 makes rotating shaft 211 second ends 2112 keep the stability of rotating, it is one big that two blade units 3 can be, one is little, respectively have flabellum 31 and protecting wire net 32, the blade angle of the flabellum 31 of this two blade unit 3 is oppositely, is placed on respectively on first end 2111 of rotating shaft 211 and second end 2112 in conjunction with fixing.
