The left and right sides of the bottom end of the navigation device body 2 are also provided with second fixed support rods 38. The bottom end of the navigation device body 2 is fixedly connected to the top end of the second fixed support rods 38. The bottom end of the second fixed support rods 38 is fixedly connected to the top end of the wind deflector 39. The second fixed support rods 38 are round rods. The bottom middle position of the first fixed plate 10 is fixedly connected to the top of the fixed sleeve block 16. The fixed sleeve block 16 is fitted with a rotating block 17. Both the inner wall of the fixed sleeve block 16 and the rotating block 17 are circular. The fixed sleeve block 16 and the rotating block 17 are rotatably connected. The bottom of the rotating block 17 is fixedly connected to the top of the first transmission plate 18. The first transmission plate 18 is a circular disc design. The bottom end of the first transmission plate 18 is fixedly connected to the top end of the fixed insert 19. The top end of the movable slide rod 15 is provided with a guide slot 20. The bottom end of the fixed insert 19 is inserted into the guide slot 20, and the fixed insert 19 and the guide slot 20 are slidably connected. The fixed insert 19 and the guide slot 20 are also square in design. A first reset spring 21 is sleeved on the outside of the fixed insert 19. The top end of the first reset spring 21 is fixedly connected to the bottom end of the first transmission plate 18. The bottom end of the first transmission plate 18 is fixedly connected to the top end of the movable slide rod 15. The front and rear ends of the top of the first groove 40 are also provided with fixed sleeves 25, and the top of the first groove 40 is fixedly connected to the top of the fixed sleeve 25. The first movable rod 26 is inserted inside the fixed sleeve 25, and the fixed sleeve 25 and the first movable rod 26 are slidably connected. The inner wall of the fixed sleeve 25 is circular. The bottom end of the first movable rod 26 is fixedly connected to the top of the third fixed plate 27. The bottom end of the third fixed plate 27 abuts against the top of the navigation device body 2. The first movable rod 26 is a circular rod design. The top end of the fixed sleeve 25 is fixedly connected to the top end of the second return spring 29, the bottom end of the second return spring 29 is fixedly connected to the top end of the limiting moving block 28, the bottom end of the limiting moving block 28 is fixedly connected to the top end of the first moving insert 26, the fixed sleeve 25 is sleeved on the outside of the limiting moving block 28, and the fixed sleeve 25 is slidably connected to the limiting moving block 28. The limiting moving block 28 is a circular design. During operation, the wind deflector 39 is first grasped and inserted into the first groove 40 at the bottom of the drone body 1. As the wind deflector 39 is inserted, it causes the navigation device body 2 at the bottom of the second fixed support rod 38 to be inserted into the first groove 40 at the bottom of the drone body 1. During insertion, the limiting plate 23 is horizontally positioned. During insertion, the navigation device body 2 moves the limiting sleeve 24 towards the limiting plate 23 until the limiting sleeve 24 is completely fitted onto the outside of the limiting plate 23. Once the limiting plate 23 is inside the limiting sleeve 24, pressure is applied to the wind deflector 39. When pressure is applied to the wind deflector 39, the limiting sleeve 24 will press against the limiting plate 23, causing the sliding rod to move. The sliding rod 15 retracts along the interior of the second fixed plate 13. When the sliding rod 15 retracts, it will drive the guide slot 20 to move along the outside of the fixed insert 19. At the same time, the bottom end of the sliding rod 15 will press the first return spring 21 at the top of the first transmission plate 18 to retract. When the sliding rod 15 moves, it will drive the guide moving rod 22 to move downward. When the guide moving rod 22 moves, it will slide to the left along the top of the first guide block 11 at the top of the first fixed plate 10, while driving the sliding rod 15 to rotate. Then, when the pressure is stopped, under the rebound force of the first return spring 21, the sliding rod 15 will rebound in the opposite direction, and the guide moving rod 22 will move upward. When the guide moving rod 22 moves upward and contacts the bottom surface of the second guide block 14, it will continue to rotate to the left along the bottom surface of the second guide block 14 until the guide moving rod 22 rotates 90 degrees and stops and is locked to the bottom of the second guide block 14. At the same time, when the moving slide rod 15 rotates, it drives the fixed insert block 19 and the first transmission plate 18 to rotate simultaneously. When the first transmission plate 18 rotates, it drives the rotating block 17 to rotate along the inside of the fixed sleeve block 16. At the same time, the first fixed support rod 12 is used to support the positions of the first fixed plate 10 and the second fixed plate 13. When the navigation device body 2 is inserted into the first groove 40 opened at the bottom of the drone body 1, the navigation device body 2 will squeeze... The third fixing plate 27 is retracted and moved, and when the third fixing plate 27 moves, it drives the first moving rod 26 to move simultaneously. The first moving rod 26 retracts and moves along the inside of the fixing sleeve 25. At the same time, when the first moving rod 26 moves, it will drive the limiting moving block 28 to move synchronously. The limiting moving block 28 moves along the inner wall of the fixing sleeve 25. When the limiting moving block 28 moves, it will squeeze the second return spring 29 to retract. When the wind deflector 39 is released, under the rebound of the second return spring 29, the limiting moving block 28 and the first moving rod 26 are driven to return to their original positions. At the same time, the third fixing plate 27 applies a pushing force to the main body 2 of the navigation device, thereby ensuring the stability after installation.

[0021] Example 2: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, in contrast to Embodiment 1 as another implementation of the present invention, the front and rear ends of the bottom of the drone body 1 are also provided with second grooves 41. The interior of the first groove 40 and the interior of the second groove 41 are interconnected. The bottom end of the second groove 41 is fixedly connected to the top end of the fourth fixing plate 30. The fourth fixing plate 30 is inserted with a second movable rod 31, and the fourth fixing plate 30 and the second movable rod 31 are slidably connected. The inner wall of the fourth fixing plate 30 is circular. The second movable rod 31 is circular. The bottom end of the second movable rod 31 is inclined. The front and rear ends of the bottom of the navigation device body 2 are also provided with fixing blocks 32. The top end of the navigation device body 2 is arc-shaped. The bottom end of the navigation device body 2 is fixedly connected to the top end of the fixing block 32. The fixing block 32 is provided with a sliding groove 33. One end of the second movable rod 31 is inserted into the sliding groove 33, and the second movable rod 31 is slidably connected to the sliding groove 33. The other end of the second movable insert rod 31 is fixedly connected to the second transmission plate 34. A third return spring 35 is sleeved on the outer side of the other end of the second movable insert rod 31. One end of the third return spring 35 is fixedly connected to the fourth fixed plate 30, and the other end of the third return spring 35 is fixedly connected to the second transmission plate 34. The second transmission plate 34 is sleeved on the outside of the fixed guide rod 36, and the second transmission plate 34 is slidably connected to the fixed guide rod 36. One end of the fixed guide rod 36 is fixedly connected to the fourth fixed plate 30, and the other end of the fixed guide rod 36 is fixedly connected to the fixed limiting block 37. The fixed guide rod 36 is a circular rod design. During operation, when the navigation device body 2 is inserted into the first groove 40, due to the arc-shaped design at the top of the navigation device body 2 and the beveled design at the bottom of the second moving rod 31, when the bottom of the navigation device body 2 contacts and moves with the top of the second moving rod 31, it will compress the second moving rod 31 inside the second groove 41 and retract it outward. The second moving rod 31 retracts along the inside of the fourth fixing plate 30. Simultaneously, the movement of the second moving rod 31 drives the second transmission plate 34 to move, and the movement of the second transmission plate 34 will drive the third return spring 35 to move synchronously, stretching and elongating it. Similarly, the movement of the second transmission plate 34 will move along the outside of the fixed guide rod 36, and the fixed limiting block 37 is used to limit the position of the second transmission plate 34. To prevent the second transmission plate 34 from detaching from the surface of the fixed guide rod 36 during movement, and to prevent the navigation device body 2 from being squeezed by the second moving rod 31 during insertion, causing the second moving rod 31 to rotate, until the navigation device body 2 is fully inserted into the first groove 40, the second moving rod 31 automatically rebounds under the rebound force of the third return spring 35 and inserts into the slide groove 33 opened in the fixed block 32 for fixation. When the wind deflector 39 applies pressure for the second time, it drives the slide groove 33 to move downward along the outside of the second moving rod 31 until the installation is completed. The navigation device body 2 automatically rebounds to its original position, and at the same time drives the fixed block 32 to move upward along the outside of the second moving rod 31 until the top of the second moving rod 31 abuts against the top of the inside of the slide groove 33.
