The motor is fixedly attached to the base, a driving gear is fixedly attached to the output shaft side of the motor, and a driven gear is fixedly attached to the rear side of the body, and the driving gear and the driven gear mesh and interlock. The driven gear is oval-shaped and follows an arc-shaped trajectory.

[0005] According to a preferred embodiment, a blade is movably attached to the shaft of the operating motor shaft of the aircraft, a blade head spinner is movably attached to one end of the blade, a lock nut is screwed onto the aircraft, and the lock nut and the blade head spinner are connected at both ends across the blade.

[0006] Furthermore, according to one preferred embodiment, a connecting through hole that fits the shaft of the actuation motor shaft is drilled inside the rear guard. Effect of the Invention

[0007] Compared with the prior art, the present invention discloses a disassembled structure of the guard and the blade, which has the following beneficial effects: 1. The guard and blade disassembly structure disclosed in this invention can be removed by removing the fixing screw of the front guard and turning it to a certain angle. The blade can be removed by turning and removing the spinner of the blade head. The rear guard can be removed by turning and removing the lock nut. After removal, it is very convenient for users to clean. After cleaning, the rear guard can be installed on the aircraft via the lock nut, the blade via the spinner of the blade head, and the front guard via the fixing screw, which is convenient and quick. 2. The guard and blade disassembly structure disclosed in this invention allows the entire fan to swing up and down through the cooperation of the drive gear and driven gear.

[0009] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are not all the embodiments, but only some of the embodiments of the present invention. Based on the embodiments of the present invention, any other embodiments obtained by a person skilled in the art without creative ingenuity are also within the scope of the claims of the present invention.

[0010] Embodiment 1 to 4 show the guard and blade disassembly structure, which includes a base 9 to which a support frame is fixedly attached at its tip, a motor body 6 movably attached to the support frame, a motor shaft having blades 3 attached to the outside of the motor shaft, and a front guard 1 and a rear guard 5 surrounding the blades. The motor is fixedly attached to the base 9, a drive gear 8 is fixedly attached to the output shaft side of the motor, and a driven gear 7 is fixedly attached to the rear side of the motor body 6, with the drive gear 8 and driven gear 7 meshing together to interlock. The driven gear 7 is oval and follows an arc-shaped trajectory.

[0011] The front guard 1 is connected to the rear guard 5 by a fixing screw, so that the front guard can be easily removed from the rear guard 5.

[0012] In this embodiment, the blade 3 is movably attached to the shaft of the operating motor shaft of the airframe 6, the blade head spinner 2 is movably attached to one end of the blade 3, and a lock nut 4 is screwed onto the airframe 6, and the lock nut 4 and the blade head spinner 2 are connected at both ends with the blade 3 in between.

[0013] The lock nut 4 and the rear guard 5 are connected to each other.

[0014] In this embodiment, a connecting through hole that fits the shaft of the actuation motor shaft is drilled inside the rear guard 5 . When the connecting through hole is provided, the rear guard 5 is not interfered with by the shaft of the actuation motor shaft when it is removed from the machine body 6, and the removal of the rear guard 5 becomes easier.

[0015] Working principle of this embodiment: When in use, the front guard 1 can be removed from the rear guard 5 simply by unscrewing the fixing screw of the front guard 1 and turning it to a certain angle. The blade 3 can be removed from the body 6 by turning the spinner 2 of the blade head. The rear guard 5 can be removed from the machine body 6 by turning the lock nut 4. The drive gear 8 is rotated by the operating motor, and when the drive gear 8 rotates, the machine body 6 is driven by the driven gear 7 and rotates around the tip of the support frame.
