Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 , Figure 2 The utility model provides an embodiment: a vertical take-off and landing aircraft with a rapidly replaceable rotor, comprising a fuselage 1, a plurality of wings 2 are fixedly connected to the outside of the fuselage 1, and the purpose is to maintain stability during the flight of the aircraft. The top of the wing 2 is rotatably connected to a connecting block 13, the inside of the connecting block 13 is rotatably connected to two rotating shafts 14, the outside of the rotating shaft 4 is fixedly connected to a threaded block 5, the inside of the connecting block 13 is slidably connected to two clamping blocks 6, the inside of the two clamping blocks 6 is threadedly connected to a threaded shaft 7, the adjacent sides of the two clamping blocks 6 are fixedly connected to a telescopic rod 9, the telescopic rod 9 is used to support the movement of a spring 10, the outer sleeve of the telescopic rod 9 is provided with an elastic component for providing static friction, the adjacent sides of the two clamping blocks 6 are detachably connected to a clamping block 12, the top of the clamping block 12 is fixedly connected to a connecting shaft 11, the top of the connecting shaft 11 is fixedly connected to a blade 13, and the blade 13 can reduce resistance and improve efficiency.

[0024] Reference Figure 1-Figure 3 The elastic component includes a spring 10, which is sleeved on the outside of the telescopic rod 9, and the two ends of the spring 10 are respectively fixedly connected to the inside of the two clamping blocks 6. The bottom of the fuselage 1 is fixedly connected with a plurality of fixed blocks 16, and the fixed blocks 16 are used to fix the two springs for relative movement. The adjacent side of the two fixed blocks 16 on the same side is fixedly connected with a fixed rod 14, which connects the two springs 15 for fixing. The outside of the fixed rod 14 is slidably connected with a sliding block 18. The outside of the fixed rod 14 is sleeved with two springs 15, which can reduce resistance when the aircraft lands. A groove 8 is provided on the outer side of the threaded shaft 7. Two searchlights 23 are fixedly connected to the outer front side of the fuselage 1, and the searchlights 23 provide safety protection in bad weather.

[0025] Reference Figure 1-Figure 3 The sliding block 18 is internally rotatably connected to a rotating shaft 2 17, and the rotating shaft 2 17 is externally rotatably connected to a rotating plate 19, and the two rotating plates 19 are internally rotatably connected to a rotating shaft 3 20. The rotating shaft 3 20 is externally fixedly connected to a connecting block 21, and the connecting block 21 is externally fixedly connected to an arc plate 22. In order to allow the aircraft to land smoothly, one end of the spring 2 15 is fixedly connected to the external side of the fixed block 16, and the other end of the spring 2 15 is fixedly connected to the external side of the sliding block 18. The sliding block 18 is connected to the rotating shaft for sliding. The external thread of the threaded block 5 is connected to the inside of the connecting block 1 3, in order to connect the blades 13 so that the rotor can be quickly replaced for the aircraft. The external thread of the threaded block 5 is connected to the top of the clamping block 6.

[0026] Compared with some devices in the prior art, the above content is that when the connecting shaft 11 is subjected to external force, it moves downward to cause the groove 8 and the threaded shaft 7 to rotate. When the connecting column moves, the groove 8 rotates, and the threaded shaft 7 moves linearly. The spring 10 also expands and contracts accordingly with the movement of the threaded shaft 7. Secondly, as the impact force is transmitted, the fixed block 16 is fixed to allow the spring 2 15 to support the fixed block 16. When the spring 2 15 is supporting, the rotating shaft 2 17 is connected to the rotating plate 19, and the rotating plate 19 is connected to the connecting block 2 21, so that very little impact is transmitted to the arc plate 22 to solve the impact problem when the aircraft lands.

[0027] Working principle: When the connecting shaft 11 is acted upon by an external force, it moves downward to make the clamping block 6 perform horizontal reciprocating motion. When the clamping block moves, the groove 8 and the threaded block 5 perform reciprocating motion. The purpose of this is to make the connecting column move up and down. When the clamping plate 6 moves, it will drive the threaded block 5 to move, and the fuselage 1 will also move accordingly. When the clamping block 6 moves, it will drive the spring 10 to contract and provide elastic support to solve the problem of the aircraft being able to quickly replace the rotor. Secondly, when the aircraft is landing, the connecting shaft 11 fixes the fixed rod 14, and one end of the spring 2 15 is fixedly connected to the fixed block 16. The spring 2 15 is used to fix the fixed block 16. In the process of the clamping block 12 supporting, the fixed rod 14 connects the two sliding blocks 18. When the sliding block 18 slides, it is connected to the rotating plate 19 through the rotating shaft 2 17, and the rotating plate 19 is connected to the connecting block 2 21, thereby reducing the impact force transmitted to the arc plate 22 to solve the problem of impact when the aircraft lands.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
