[0027] Embodiment 1:

[0028] The oblique photography three-dimensional model 3D visualization equipment includes an unmanned aerial vehicle 1, support feet 2 and a rotating shaft 3. Two support feet 2 are symmetrically and fixedly connected to the bottom of the unmanned aerial vehicle 1, and the rotating shaft 3 is rotatably connected to the middle of the bottom of the unmanned aerial vehicle 1;

[0029] An installation bracket 4 is rotatably connected to the outside of the rotating shaft 3, and the installation bracket 4 is distributed in an inverted U-shaped structure at the bottom of the unmanned aerial vehicle 1. The middle of the top of the installation bracket 4 is rotatably connected to the rotating shaft 3. An inner side of the installation bracket 4 is rotatably connected to a fixing plate 6, and the installation bracket 4 and the fixing plate 6 form a pan-tilt structure.

[0030] A steering gear 5 is fixedly connected to one side of the installation bracket 4, and mounting shafts 8 are fixedly connected to both ends of the fixing plate 6. The output end of the steering gear 5 is fixedly connected to one of the mounting shafts 8.

[0031] Two symmetrically distributed reinforcing rods 7 are fixedly connected to the middle of the fixing plate 6, and a chute 9 is provided at the bottom of the fixing plate 6, and the chute 9 penetrates through both ends of the bottom of the fixing plate 6.

[0032] Two clamping plates 10 are slidably connected inside the chute 9, and racks 11 are fixedly connected to the sides of the clamping plates 10 close to each other. The two clamping plates 10 are rotationally symmetrically distributed inside the chute 9.

[0033] At the mutually remote ends of the two clamping plates 10, there are symmetrically arranged extension blocks fixedly connected thereto and extending towards the middle of the fixed plate 6. A camera 16 is snap-fitted between the two extension blocks. On both sides of the camera 16, there are card slots 17, and the inside of the card slots 17 is snap-fitted with the extension blocks.

[0034] In the middle of the inside of the chute 9, a gear 12 is rotatably connected. On both sides of the gear 12, the gear 12 meshes with the two racks 11 respectively, and the top of the gear 12 extends upwards into the inside of the fixed plate 6.

[0035] The top of the gear 12 is fixedly connected with a worm gear 13. The worm gear 13 is located on the top of the fixed plate 6. On the outside of the worm gear 13, there is a worm 14 threadedly connected thereto. The worm 14 is located on the top of the fixed plate 6, and the end of the worm 14 is fixedly connected with a self-tightening rod 15.

[0036] Embodiment 2:

[0037] Based on Embodiment 1, its specific working principle is as follows:

[0038] During the use of the tilt photography three-dimensional model 3D visualization equipment, the drone 1 will drive the camera 16 to move. During the movement, the drone 1 will remain stable in the air. Since the mounting frame 4 and the steering gear 5 form a pan-tilt structure, at this time, the mounting frame 4 is driven to rotate through the rotating shaft 3, and at the same time, the fixed plate 6 is driven to rotate through the steering gear 5, so that the horizontal and vertical angles of the camera 16 at the bottom are adjusted simultaneously, thereby increasing the shooting range of the camera 16. At the same time, the angle of the camera 16 can be adjusted during the movement of the drone 1 and the camera 16, improving the flexibility of the camera 16 shooting;

[0039] During the disassembly of the camera 16, first rotate the self-tightening rod 15, so that the self-tightening rod 15 rotates on the top of the fixed plate 6. While the self-tightening rod 15 rotates, the self-tightening rod 15 will drive the worm gear 13 to rotate on the top of the fixed plate 6, and then the worm gear 13 drives the gear 12 to rotate inside the chute 9. Since the gear 12 meshes with the rack 11, at this time, the gear 12 will drive the two racks 11 to move away from each other, so that the two clamping plates 10 move away from each other following the racks 11. At this time, the extension blocks at the ends of the two clamping plates 10 will move away from each other, so that the inside of the clamping plates 10 and the card slots 17 on both sides of the camera 16 are separated, and then the camera 16 is disassembled;

[0040] During the installation of the camera 16, first place the camera 16 at the bottom of the fixing plate 6. At this time, rotate the self-tapping rod 15 to drive the two clamping plates 10 to approach each other, so that the extension blocks at the ends of the two clamping plates 10 are engaged with the inside of the card slot 17, thereby completing the installation of the camera 16. The transmission structure formed between the worm 14 and the worm wheel 13 has self-locking property, making the worm wheel 13 unable to rotate by itself, thus fixing the rotation angle of the gear 12 and maintaining the stability of the clamping plate 10 in fixing the camera 16.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium.
