The outdoor electric fan adopting the structure can realize the unfolding and folding of the electric fan through the sliding of the motor; the fan blade is driven to rotate and the supporting rod is driven to rotate through the matching of the embedded block and the first embedded groove and the second embedded groove respectively, the supporting rod is driven to rotate to conveniently drill the supporting rod into the outdoor ground, and the fan is convenient to position.
In the above technical scheme, preferably, the support rod is detachably connected with the drill bit through threads. Adopt this structure to make and can pull down the drill bit after the electric fan is accomodate to reduce the danger of carrying the drill bit in the transportation.
In the above technical solution, preferably, a positioning rod is disposed on a side surface of the supporting rod, and when the positioning rod is clamped into the clamping portion, the electric fan is in a furled state. The positioning rod is arranged to fix the motor on the supporting rod after the electric fan is folded, so that the electric fan is prevented from being unfolded accidentally.
Compared with the prior art, the invention has the following beneficial effects: the outdoor electric fan adopting the structure can realize the unfolding and folding of the electric fan through the sliding of the motor; meanwhile, when the electric fan is unfolded, the fan blades are driven to rotate by the motor, and when the electric fan is folded, the supporting rod is driven by the motor to rotate, so that the supporting rod can be conveniently drilled into the outdoor ground, and the positioning of the fan is facilitated.
