Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, a cadastral mapping drone includes a drone body 1. Connecting rods 2 are fixedly installed at the four corners of the drone body 1. A propeller is mounted on the upper side of each connecting rod 2. A first movable cavity 3, which is fan-shaped, is formed inside the drone body 1. A swing block 4 is movably installed inside the first movable cavity 3. A first mounting cavity 5 is formed on the side of the swing block 4. A fixed camera 6 is installed inside the first mounting cavity 5. Two second movable cavities 7, which are arc-shaped, are symmetrically formed inside the first movable cavity 3. A first snap-fit ​​structure is fixedly installed on the side of the swing block 4 corresponding to the position of the second movable cavity 7. Two adapter cavities 8, which are arc-shaped grooves, are symmetrically formed on the side of the swing block 4. Two fixed support frames 9, which are arc-shaped blocks that adapt to the adapter cavities 8, are provided on the bottom side of the drone body 1. One end of each support frame 9 is provided with... A second locking structure is adapted to the first locking structure. A pressing block 14 is provided on the inner side of the second movable cavity 7 to press the first locking structure. When not in operation, the pressing block 14 presses the first locking structure to fix the swing block 4, so that the camera 6 is located inside the first movable cavity 3 to protect the camera lens and reduce unnecessary wear caused by collision with insects during flight. When flying, the swing block 4 starts to swing, so that the first locking structure and the second locking structure fit together to form a hard limit on the movement of the swing block 4. The first locking structure and the second locking structure also constrain and press the swing block 4 to improve stability. A second mounting cavity 18 is opened on the side of the drone body 1. A fixed rotary motor 19 is provided inside the second mounting cavity 18. The output end of the rotary motor 19 is fixedly installed on the side of the swing block 4.

[0026] The first snap-fit ​​structure includes a mounting block 10 fixedly installed on the side of the swing block 4. A limiting block 11 is fixedly installed on the side of the mounting block 10. The limiting block 11 is a trapezoidal block. The inclined surface of the limiting block 11 guides the snap-fit ​​position of the second snap-fit ​​structure. A limiting cavity 13 is opened at the center of the side of the limiting block 11. The limiting cavity 13 is an arc-shaped cavity. The squeezing block 14 is a hollow arc-shaped block. The squeezing block 14 squeezes into the interior of the limiting cavity 13 to constrain the movement of the limiting block 11 and the mounting block 10, thereby constraining the movement of the swing block 4. The second snap-fit ​​structure includes a connecting block 20 fixedly installed at one end of the support frame 9. The connecting block 20 is a trapezoidal block. A claw 12 is fixedly installed at one end of the connecting block 20. The claw 12 is an arc-shaped block adapted to the side of the limiting block 11. The connecting block 20 and the limiting block 11 perform a snap-fit ​​operation. The movement of the limiting block 11 is constrained by the deformation of the connecting block 20.

[0027] A first support rod 15 is fixedly installed on the upper side of the support frame 9. The end of the first support rod 15 away from the support frame 9 is fixedly installed on the side of the drone body 1. Two second support blocks 16 are symmetrically fixedly installed on the upper side of the support frame 9. The end of the second support block 16 away from the support frame 9 is fixedly installed on the side of the drone body 1. Two protrusions 17 are arc-shaped blocks fixedly installed on the bottom side of the support frame 9. The first support rod 15, the second support blocks 16, the support frame 9 and the protrusions 17 form a support frame 9 to support the drone body 1.

[0028] The working principle of this utility model:

[0029] In use, when not in operation, the squeezing block 14 presses against the first locking structure to fix the swing block 4, keeping the camera 6 inside the first movable cavity 3 to protect the camera lens and reduce unnecessary wear caused by collisions with insects during flight. When in flight, the swing block 4 begins to swing, causing the first and second locking structures to fit together to create a hard limit on the movement of the swing block 4. The first and second locking structures also constrain and compress the swing block 4. To improve stability, the inclined surface of the limiting block 11 guides the snap-fit ​​position of the second snap-fit ​​structure. The pressing block 14 presses into the interior of the limiting cavity 13 to constrain the movement of the limiting block 11 and the mounting block 10, thereby constraining the movement of the swing block 4. The connecting block 20 snaps into the limiting block 11, and the deformation of the connecting block 20 constrains the movement of the limiting block 11. The first support rod 15, the second support block 16, the support frame 9 and the protrusion 17 form a support frame 9 to support the main body of the drone 1.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
