[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a retractable drone with a cargo delivery hook structure, including a connecting seat 1. A rotating shaft 12 is rotatably connected inside the connecting seat 1. A cylinder 2 is fixedly connected to the outer wall of the rotating shaft 12. A connecting rod 3 is fixedly connected to the output end of the cylinder 2. A rotating block 4 is rotatably connected to the outer wall of the connecting rod 3. A support column 5 is fixedly connected inside the rotating block 4. The outer wall of the support column 5 is rotatably connected to the inside of the connecting seat 1. A clamping rod 6 is fixedly connected to the lower surface of the rotating block 4. A hook 7 is connected to the outer wall of the clamping rod 6. An insert block 8 is fixedly connected to the outer wall of the hook 7. The outer wall of the insert block 8 is slidably connected to the inside of the clamping rod 6. A locking post 9 is slidably connected to the inside of the locking post 8. A fixing post 10 is slidably connected to the outer wall of the locking post 9. The outer wall of the fixing post 10 is fixedly connected to the inside of the clamping rod 6. A first spring 11 is fixedly connected to the outer wall of the locking post 9. The outer wall of the first spring 11 is fixedly connected to the inside of the fixing post 10. A connecting assembly is provided on the upper surface of the connecting seat 1.

[0024] Specifically, the rotating shaft 12, inside the connecting seat 1, supports and fixes the cylinder 2. Activating the cylinder 2 pushes the connecting rod 3 to slide, which in turn causes the rotating block 4 to rotate. The supporting column 5, inside the connecting seat 1, supports the rotation of the rotating block 4, ensuring its stable rotation. The rotating block 4 fixes the clamping rod 6, causing it to rotate synchronously. The insert block 8 connects the clamping rod 6 and the hook 7. Rotation of the clamping rod 6 allows the hook 7 to grip or lift goods. When the hook 7 is deployed, the fixed post 10 is fixed inside the clamping rod 6 to support the locking post 9. The locking post 9 also serves to limit and fix the insert block 8. When the locking post 9 is locked inside the insert block 8, the hook 7 and the clamping rod 6 can be limited and fixed. Conversely, when the hook 7 needs to be replaced, simply pull the hook 7. The first spring 11, which is located between the fixed post 10 and the locking post 9, will be squeezed due to the sliding of the locking post 9, thereby allowing the locking post 9 to slide inside the fixed post 10, releasing the restriction on the insert block 8, and the hook 7 can be removed from the clamping rod 6 for replacement.

[0025] Reference Figure 1 and Figure 2 The connecting component includes a connecting block 13, the lower surface of which is fixedly connected to the upper surface of the connecting seat 1, and the upper surface of which is fixedly connected to the organism 14.

[0026] Specifically, the connecting block 13 serves to connect the body 14 and the connecting seat 1, providing a supporting foundation for the entire drone.

[0027] Reference Figure 1 and Figure 4 An arm 15 is fixedly connected inside the body 14. A telescopic arm 16 is slidably connected inside the arm 15. An insertion hole 17 is opened inside the telescopic arm 16. A fixing block 18 is fixedly connected to the outer wall of the arm 15. A sliding plate 19 is slidably connected inside the fixing block 18. A sliding piece 23 is fixedly connected to the lower surface of the sliding plate 19. The outer wall of the sliding piece 23 is slidably connected to the inner wall of the fixing block 18. A limit post 20 is fixedly connected to the outer wall of the limit post 20. A second spring 21 is slidably connected to the outer wall of the limit post 20. One end of the second spring 21 is fixedly connected to the outer wall of the sliding piece 23. The other end of the second spring 21 is fixedly connected to the inside of the fixing block 18. An insertion rod 22 is fixedly connected to the outer wall of the sliding piece 23. The outer wall of the insertion rod 22 is slidably connected to the inside of the fixing block 18, the inner wall of the insertion rod 22 is slidably connected to the inside of the arm 15, and the inner wall of the insertion rod 22 is slidably connected to the inner wall of the insertion hole 17.

[0028] Specifically, the fuselage 14 supports and fixes the arm 15, the telescopic arm 16 extends the arm 15, and the distance between the telescopic arm 16 and the arm 15 can be adjusted according to different flight requirements. The fixing block 18 is fixed to the outer wall of the arm 15 and supports the sliding plate 23. The sliding plate 19 fixes the sliding plate 23. By pushing the sliding plate 19, the sliding plate 23 can slide synchronously inside the fixing block 18. The sliding plate 23 fixes the limiting post 20 and allows the limiting post 20 to slide synchronously. The sliding limit post 20 restricts the movement of the slide plate 19. The second spring 21 is located between the fixed block 18 and the slide plate 23. It will be squeezed by the sliding of the slide plate 23. The slide plate 23 fixes the insertion rod 22, so that the insertion rod 22 slides synchronously in the arm 15, the fixed block 18 and the insertion hole 17. The telescopic arm 16 has multiple insertion holes 17. Different insertion holes 17 can be selected according to different needs. The telescopic arm 16 and the arm 15 can be fixed and adjusted by sliding the insertion rod 22 in and out.

[0029] Working principle: When the drone is needed, the position between the boom 15 and the telescopic boom 16 is adjusted. Pulling the slide plate 19 causes the slide plate 23 to slide, and during the sliding process, it compresses the second spring 21. When the slide plate 23 slides, it simultaneously causes the insertion rod 22 to slide out of the insertion hole 17. At this time, the telescopic boom 16 can slide inside the boom 15 and be aligned with the appropriate insertion hole 17. Releasing the slide plate 19 allows the rebound of the second spring 21 to push the insertion rod 22 in the opposite direction and lock it into the inner wall of the insertion hole 17 through the slide plate 23. This limits and fixes the position between the boom 15 and the telescopic boom 16, achieving the effect of meeting different flight requirements while also facilitating transportation and storage.

[0030] When it is necessary to grip the goods, cylinder 2 is activated. Cylinder 2 will push the rotating block 4 to rotate through the connecting rod 3. When the rotating block 4 rotates, it will simultaneously drive the gripping rod 6 and the hook 7 to rotate, thereby realizing the gripping and delivery of goods. The hook 7 is prone to wear during long-term use. When it needs to be replaced, simply pull the hook 7. The hook 7 will drive the insert block 8 to slide inside the gripping rod 6. When the insert block 8 slides, it will also squeeze the locking post 9, causing it to slide inside the fixed post 10. During the sliding process, it will squeeze the first spring 11. When the locking post 9 slides out of the insert block 8, the hook 7 and the insert block 8 can be removed from the inside of the gripping rod 6 for replacement. This achieves the effect of facilitating the gripping and delivery of goods while also facilitating the replacement of the hook 7. This drone can not only adjust the distance between the arm 15 and the telescopic arm 16 to meet different flight requirements, but also facilitate transportation and storage. It can also automatically grip and deliver goods while facilitating the replacement of the hook 7.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
