The below of housing is provided with fan base, and fan base comprises the connecting rod, positioning seat, retractable supports seat and the base that connect successively from top to bottom; The upper end of connecting rod is fixed on the position of contiguous front side, housing bottom surface, the upper end pivot joint of lower end and positioning seat; Retractable supports seat comprises main bearing and is embedded in the secondary bearing in main bearing; Positioning seat is fixed on the position of the contiguous front side of secondary bearing end face; The sidewall of secondary bearing is fixedly connected with the sidewall of main bearing by some fastening pieces arranged along the longitudinal direction.
Further, the sidewall of secondary bearing is provided with the locking face matched with described fastening piece.
Further, connecting rod and positioning seat are by bolt pivot joint.
Further, fastening piece is lock screw.
The beneficial effects of the utility model are:
1, flabellum of the present utility model can stretch one by one or shrink, and when not using this electric fan, by the first blade and the second vanes retract in Three-blade, can change fan blade area size and conveniently collect placement, and can prevent dust from falling thereon.
2, secondary bearing of the present utility model can slide in main bearing, adjustable electric fan height.
3, being of the present utility modelly provided with electric accumulator, when having a power failure, still can working.
4, connecting rod of the present utility model is flexibly connected with positioning seat, when not using this electric fan, and can by the rearward end of drive unit to pressing on secondary bearing.
In sum, this electric fan when not using, first by the first blade and the second vanes retract in Three-blade, then by the rearward end of drive unit to pressing on secondary bearing, finally again by flabellum seat to pressing down, make in whole device indentation motor cabinet.The utility model floor space is little, the flabellum page not easily dust stratification, is convenient to collection.
