In order to solve the technical problem, the invention is solved by the following technical scheme: an outdoor electric fan comprises a motor, wherein the motor comprises a stator of an outer ring and a rotor of an inner ring, the rotor is provided with a polygonal through hole, the polygonal through hole is provided with a polygonal rotating shaft matched with the polygonal through hole, one end of the polygonal rotating shaft is connected with a front end face through a first bearing, the periphery of the front end face is rotationally connected with one end of a plurality of front frameworks, the outer side of the stator is rotationally connected with one end of a plurality of rear frameworks, the other ends of the front frameworks are rotationally connected with the other ends of the rear frameworks in a one-to-one correspondence manner, fan blades are rotationally arranged on the polygonal rotating shaft between the front end face and the motor, convex rings used for positioning the fan blades are arranged on the polygonal rotating shaft, the other end of the polygonal rotating shaft is connected with a supporting rod through a second bearing, the supporting rod has the same peripheral, the electric fan is characterized in that a clamping part is arranged on the side face of the stator, when the supporting rod is clamped into the clamping part, the electric fan is in an unfolded state, and a drill bit is arranged at the end part of the supporting rod. 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.
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.
