The main shaft 110 rotates under the operation of the stator 130 and the rotor 120 to generate a rotation torque, and the rotation torque is transmitted to the blades 310a slidably connected to the first end 111 of the main shaft 110, so as to rotate the blades 310 a. Wherein the stator 130 and the rotor 120 can generate an electromagnetic field when working together.

The driving assembly 100 further includes a first elastic member 140, and one end of the first elastic member 140 is connected to the first end of the main shaft 110.

Under the elastic force of the first elastic member 140, the long pin 210 can move away from the stator 130 along the axial direction of the main shaft 110, that is, the abutting end 212 of the long pin 210 abuts against the root 310b of the blade 310a, so as to drive the root 310b of the blade 310a to slide along the direction perpendicular to the axial direction, so as to increase the diameter of the blade 310 a. In the propeller 10, the first elastic member 140 is provided, so that one end of the first elastic member 140 is connected to the first end of the main shaft 110, and the other end of the first elastic member 140 abuts against the connecting end 211 of the long pin 210. Through the above connection manner, the long pin 210 can move away from the stator 130 along the axial direction of the main shaft 110 under the action of the elastic force of the first elastic member 140, that is, the abutting end 212 of the long pin 210 abuts against the root 310b of the blade 310a, so as to drive the root 310b of the blade 310a to slide along the direction perpendicular to the axial direction, so as to increase the diameter of the blade 310 a.

Optionally, referring to fig. 3, fig. 3 is a schematic structural view of another embodiment of the long pin of the present application. As shown, the first moving assembly 200 includes a gear 230 and a toothed chain 240, one end of the toothed chain 240 is connected to the long pin 210, and the other end of the toothed chain 240 is connected to the blade root 310b through the gear 230. When the long pin 210 moves toward the stator 130 along the axial direction of the main shaft 110, the toothed chain 240 is driven to move in the same direction, and the gear 230 draws the blade root 310b relative to the main shaft 110, so as to change the diameter of the blade 310 a.

Referring to fig. 4, fig. 4 is a schematic structural diagram of an embodiment of a spindle and an armature of the present application.

The middle portion of the armature 220 of the first moving assembly 200 is embedded in the first through hole 115 of the main shaft 110 and is located between the first elastic member 140 and the long pin 210. When the driving assembly 100 works, the rotor 120 and the stator 130 work in a matching manner to generate an electromagnetic field, the main shaft 110 drives the armature 220 to rotate when rotating, the outer periphery of the armature 220 extends to one side of the stator 130 close to the paddle 310a, the armature 220 rotates to cut the electromagnetic field, and thus the electromagnetic field generates a magnetic attraction force on the armature 220. When the magnetic attraction force of the electromagnetic field is greater than the elastic force of the first elastic member 140 to the armature 220, the armature 220 moves toward the side close to the stator 130, thereby driving the long pin 210 to move along the axial direction of the main shaft 110 close to the side of the stator 130, weakening the force of the abutting end 212 of the long pin 210 to the root 310b of the blade 310a, further driving the root 310b of the blade 310a to close relative to the main shaft 110, and shortening the diameter of the blade 310 a. When the magnetic attraction force of the electromagnetic field is smaller than the elastic force of the first elastic member 140 to the armature 220, the armature 220 moves towards the side away from the stator 130, so as to drive the long pin 210 to move towards the side away from the stator 130 along the axis direction of the main shaft 110, enhance the force of the abutting end 212 of the long pin 210 to the root 310b of the blade 310a, further drive the root 310b of the blade 310a to extend relative to the main shaft 110, and increase the blade diameter of the blade 310 a.
