Frisbee

A frisbee, comprising:

• a rotating shaft and a surface cover, a first fan blade, a second fan blade, a fan blade gear, a third fan blade and a bottom case arranged in sequence, and the first fan blade comprises a first casing and a plurality of first blades arranged on the outer wall of the first casing, the second fan blade comprises a second casing and a plurality of second blades arranged on the outer wall of the second casing, and the two ends of the rotating shaft are respectively rotatably connected to the surface cover and the bottom case, and the rotating shaft passes through the first casing, the second casing, the fan blade gear and the third fan blade in turn, and the fan blade gear and the third fan blade rotate synchronously around the rotating shaft;
• a cavity formed by the first casing and the second casing is arranged with an electric motor and a main board, an output end of the electric motor protrudes from the second casing, and the output end of the electric motor is arranged with a motor gear meshing with the fan blade gear, the main board is arranged on the first casing, and a switch button is arranged on the first casing, and the switch button is connected with the main board, and the main board is connected to the electric motor, and the surface cover is arranged with a first through hole corresponding to the switch button;
• when the switch button is pressed through the first through hole, the electric motor rotates drives the motor gear to rotate, drives the fan blade gear to rotate, drives the third fan blade to rotate, and makes the frisbee fly up;
• wherein the surface cover is arranged with a first limiting column and a second limiting column arranged on the first limiting column, and the bottom case is arranged with a first limiting groove and a second limiting groove connected to each other, the width of the second limiting groove is the same as the diameter of the first limiting column, the width of the first limiting groove is the same as the diameter of the second limiting column, and the diameter of the first limiting column is smaller than the diameter of the second limiting column, after the second limiting column passes through the first limiting groove, the surface cover is rotated relative to the bottom case, so that the first limiting column enters the second limiting groove, and the second limiting groove limits the axial movement of the second limiting column so as to connect the surface cover and the bottom case.
