A fixing mechanism is installed inside the slider 8. The fixing mechanism quickly fixes and installs different modules. A support leg 2 is fixedly connected to the bottom of the body 1. The support leg 2 provides overall support for the aircraft, making the body 1 more stable.

[0036] The fixing mechanism includes a sliding component and a snap-fit ​​component. The snap-fit ​​component includes a second slide rod 15, which is slidably connected inside the first slider 8. Multiple snap-fit ​​blocks 17 are fixedly connected to the outside of the second slide rod 15. When the second slide rod 15 is moved, it drives the snap-fit ​​blocks 17 to move. An insert block 19 is slidably connected inside the first slider 8. An insertion hole 18 is opened in the middle of the first slider 8. The insert block 19 is slidably connected inside the insertion hole 18, allowing insert blocks 19 of different modules to be selected and inserted into the appropriate insertion hole 18. A fixing hole 22 is opened on the outside of the insert block 19. The snap-fit ​​blocks 17 snap into the insert block 19. Moving the second slide rod 15 moves the snap-fit ​​blocks 17, inserting the insert block 19 into the insertion hole 18. Then, moving the second slide rod 15 resets the position, fixing the snap-fit ​​blocks 17 and the fixing holes 22 on the outside of the insert block 19, thus fixing the insert block 19. This enables the rapid fixing and installation of different functional modules, greatly improving convenience and work efficiency.

[0037] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6The sliding assembly includes a slide rod 11, which is slidably connected inside a slider 8. A groove 14 is provided inside the slider 8, and the slide rod 11 is slidably connected inside the groove 14. The end of the slide rod 15 is tightly fitted with the end of the slide rod 11. Pressing the slide rod 11 moves the slide rod 15, which in turn moves the locking block 17. A spring 16 is installed inside the slider 8. When the slide rod 15 is pushed, it compresses the spring 16. When the slide rod 11 is released, the slide rod 15 is released from the spring 16. Under the action of spring 16, the slide bar 17 can be reset and engaged with the fixing hole 22 to achieve the fixed installation of the insert block 19. The outer side of the slide bar 11 is fixedly connected to the slider 12. The inside of the slider 11 is provided with a groove 13. The slider 12 is slidably connected inside the groove 13. Pressing the slide bar 11 moves the slider 12, thereby driving the slider 12 to slide. The slider 12 limits the slide bar 11. When the press of the slide bar 11 is released, the slide bar 15 rebounds and resets under the action of the spring 16. The slide bar 15 pushes the slide bar 11 to reset.

[0038] Reference Figures 1-4 The adjustment mechanism includes a drive assembly and a moving assembly. The drive assembly includes a knob 4, which is rotatably connected to the outside of the fixed block 3. A bevel gear 5 is fixedly connected to the end of the knob 4. Rotating the knob 4 drives the bevel gear 5 to rotate. A bidirectional threaded rod 7 is rotatably connected inside the fixed block 3. A slider 8 is threadedly connected to the outer circumference of the bidirectional threaded rod 7. A bevel gear 6 is fixedly connected to the outer circumference of the bidirectional threaded rod 7. The bevel gear 5 and the bevel gear 6 are engaged. When the bevel gear 5 rotates, it drives the bevel gear 6 to rotate. The rotating bevel gear 6 drives the bidirectional threaded rod 7 to rotate, thus moving the slider 8. The moving assembly includes a support block 9, which is fixedly connected to the bottom of the body 1. The support block 9 is connected to the fixed block 3. Together, they are fixed to the bottom of the body 1 to connect and fix the bottom mechanism. The support block 9 is rotatably connected to the fixing rod 10. The slider 8 is slidably connected to the outer periphery of the fixing rod 10. When the slider 8 moves through the bidirectional threaded rod 7, the other end slides through the fixing rod 10, which supports the slider 8 and limits its movement to prevent it from shifting. The outside of the insert block 19 is equipped with a support rod 20. The bottom of the support rod 20 is fixedly connected to the jacking box 21. The jacking box 21 is connected to the insert block 19 through the support rod 20, thus fixing it to the bottom of the aircraft. The jacking box 21 can be quickly separated from the insert block 19 for replacement, allowing for rapid installation and disassembly of the payload, greatly improving work efficiency.

[0039] Working principle: First, press one slide bar 11 to move slide bar 2 15. Moving slide bar 2 15 compresses spring 16 and simultaneously moves the locking block 17, allowing the insert block 19 to be inserted into the appropriate insertion hole 18. Turning knob 4 drives bevel gear 1 5 to rotate, which in turn drives bevel gear 2 6 to rotate, thereby driving the bidirectional threaded rod 7 to rotate. The bidirectional threaded rod 7 drives the two sliders 1 8 to move closer for adjustment. At the same time, press the other slide bar 11 to insert the insert block 19 into the insertion hole 18. Releasing slide bar 11 causes slide bar 2 15 to spring back under the action of spring 16. At this time, the locking block 17 engages with the fixing hole 22, allowing different objects to be quickly fixed to the bottom of the aircraft through the insert block 19, enabling the rapid installation and removal of the payload and greatly improving work efficiency.
