[0039] Example 2

[0040] Reference Figure 4 , which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that the limiting member 105 includes an inclined plate 105a hinged on the slide groove 104f, a second spring 105b symmetrically installed on the inclined plate 105a, a support plate 105c fixedly installed on the connecting rod 104h, a long rod 105d inserted between the support plate 105c and the fixed block 104g, a third spring 105e sleeved on the surface of the long rod 105d, and a pressure plate 105f fixedly installed on the long rod 105d.

[0041] Specifically, one end of the inclined plate 105a contacts one side of the connecting rod 104h, thereby limiting the connecting rod 104h. A short block is fixedly installed on the surface of the long rod 105d, and the short block is located between the support plate 105c and the fixed block 104g. The third spring 105e is located between the short block and the support plate 105c. The connecting rod 104h can be reset by the third spring 105e. The pressure plate 105f is arranged on the side close to the inclined plate 105a.

[0042] Furthermore, a plurality of circular grooves are formed on the surface of the housing 103. One end of the long rod 105d away from the pressing plate 105f extends to the outside of the housing 103 and is located between the circular grooves. A pressing plate is fixedly connected to this end, and the shape and size of the pressing plate are consistent with the circular grooves.

[0043] The rest of the structure is the same as that of Example 1.

[0044] Operation process: when the connecting rod 104h contacts the slide groove 104f, the bottom end of the connecting rod 104h will contact the bottommost surface of the top inclined surface of the inclined plate 105a. As the connecting rod 104h moves, the inclined plate 105a will be gradually squeezed. After the connecting rod 104h moves into place, the bottom end of the connecting rod 104h will no longer contact the top of the inclined plate 105a. The inclined plate 105a can be reset by the reaction force of the second spring 105b, so that one end of the inclined plate 105a contacts one side of the connecting rod 104h, thereby holding the connecting rod 104h against and fixing it. When the housing 103 needs to be disassembled, the pressing plate in the circular groove is pressed toward the depth of the circular groove, and the long rod 1 is pushed through the pressing plate. 05d moves, and the long rod 105d moves, while the pressure plate 105f and the short block are moved synchronously, the third spring 105e is squeezed by the short block, and the pressure plate 105f contacts the top of the inclined plate 105a, and the inclined plate 105a is squeezed, so that one end of the inclined plate 105a is no longer in contact with the connecting rod 104h, and then the shell 103 is pulled to move the connecting rod 104h out of the slide groove 104f, thereby completing the disassembly of the shell 103, and the inclined plate 105a is reset again by the second spring 105b, and then the pressure plate is released. At this time, the reaction force of the third spring 105e enables the short block to be reset, and the pressure plate 105f and the long rod 105d are driven to reset by the short block.

[0045] Example 3

[0046] Reference Figure 5 - Figure 6 , which is the third embodiment of the utility model. This embodiment is different from the above embodiments in that the transmission member 205 includes a fourth gear 205a symmetrically rotatably mounted on the special-shaped plate 102, a round block 205b fixedly mounted on the fourth gear 205a, a rotating plate 205c rotatably mounted on the special-shaped plate 102, a connecting plate 205d arranged between the rotating plate 205c and the round block 205b, and a wing 205e mounted on the rotating plate 205c. The shape of the wing 205e is similar to that of a butterfly wing and is made of PET.

[0047] Specifically, the first gear 202 is meshed with the second gear 203, the third gear 204 is meshed with the fourth gear 205a, the round block 205b is arranged on the side away from the second gear 203, and a rotating shaft is arranged at the connection between the connecting plate 205d, the rotating plate 205c and the round block 205b. The connecting plate 205d will not rotate with the round block 205b through the rotating shaft, but will only reciprocate up and down through the continuous pulling of the round block 205b.

[0048] The rest of the structure is the same as that of Example 2.

[0049] Operation process: When in use, the hollow cup motor 201 can operate and drive the first gear 202 to rotate. The second gear 203 will also rotate synchronously through meshing, and the third gear 204 will be driven to rotate through the second gear 203. Because the meshing makes the fourth gear 205a mesh with each other, it will also drive the round block 205b to rotate. Through the rotating shaft, the connecting plate 205d will not rotate with the round block 205b, but will only move up and down through the continuous pulling of the round block 205b, thereby driving the rotating plate 205c, so that the rotating plate 205c drives the wing 205e to move up and down, so that the device can imitate the flight of a butterfly.

[0051] Reference Figure 7 , which is the fourth embodiment of the utility model. This embodiment is different from the above embodiments in that this embodiment provides a bionic butterfly aircraft, including the above-mentioned driving mechanism, a receiving component 300, an adjustment plate 301 installed on the skeleton 101 with screws, a controller is arranged inside the adjustment plate 301, and a square block 302 and a protective shell 303 are arranged on the adjustment plate 301.

[0052] Specifically, the square block 302 is located directly above the protective shell 303. A signal receiver of model SYT-CDMA / DCS-30 is arranged inside the square block 302. The signal receiver executes instructions by transmitting instructions, modulating signals, transmitting signals, receiving signals, signal processing, demodulating, decoding, executing instructions and feedback. The size of the square block 302 is smaller than the protective shell 303. The protective shell 303 is a power source, which supplies power to the signal receiver, the hollow cup motor 201 and the controller. Both sides of the protective shell 303 are set to arc surfaces.

[0053] The rest of the structure is the same as that of Example 3.

[0054] Operation process: The operator issues a command so that the signal receiver in the square block 302 receives the command, so that the power supply can supply power to the hollow cup motor 201 to make it operate, so that the device can imitate the flight of a butterfly. At the same time, through the weight of the square block 302 and the protective shell 303, the weight of the front and rear ends of the device is kept consistent, thereby ensuring the flight effect. The square block 302 and the protective shell 303 can also prevent the internal signal receiver and power supply from contacting high humidity or moisture in the air.
