The outer ring of the first bearing 18 is fixedly connected to the inner wall of the arc tube 11, and the inner ring of the first bearing 18 is fixedly connected to one end of the first rotating shaft 20. Two limit discs 19 are sleeved on the first rotating shaft 20, and the limit discs 19 are fixedly connected to the first rotating shaft 20. Two connecting ropes 27 are arranged between the two limit discs 19. One ends of the two connecting ropes 27 are respectively fixedly connected to the left and right sides of the first rotating shaft 20. The other ends of the two connecting ropes 27 are both fixedly provided with arc-shaped rods 12. The arc-shaped rods 12 are slidably connected in the arc tube 11. A spring 26 is arranged between the arc-shaped rods 12 and the first rotating shaft 20. One end of the spring 26 is fixedly connected to the arc-shaped rod 12, and the other end of the spring 26 is fixedly connected to the inner wall of the arc tube 11. The other end of the first rotating shaft 20 penetrates through the arc tube 11 and extends outside the arc tube 11. A first bevel gear 21 is sleeved on the other end of the first rotating shaft 20, and the first bevel gear 21 is fixedly connected to the first rotating shaft 20. The first bevel gear 21 is meshed with a second bevel gear 22. The second bevel gear 22 is sleeved on one end of a second rotating shaft 23, and the second bevel gear 22 is fixedly connected to the second rotating shaft 23. The other end of the second rotating shaft 23 is fixedly connected to the inner ring of a second bearing 25, and the outer ring of the second bearing 25 is fixedly connected to the outer wall of the arc tube 11. A gear 24 is fixedly sleeved on the second rotating shaft 23. A plurality of teeth 16 are fixedly arranged on the top surface of the outer slide rail 14 along the length direction of the outer slide rail 14. The gear 24 is meshed with the teeth 16. The end of the arc-shaped rod 12 away from the spring 26 is fixedly provided with a conical plug 31.

[0035] During use, place the item to be photographed on the photography table 1, and then adjust the positions of the 360-degree camera 8 and the fill light 13. Taking the initial positions of the 360-degree camera 8 and the fill light 13 at the first photography guide rail 5 as an example, at this time, the arc tube 11 is located at the notch of the first photography guide rail 5, and the arc rod 12 is inserted into the first photography guide rail 5.

[0036] If the 360-degree camera 8 is far from the item at this time and needs to be moved closer, push the outer slide rail 14 towards the item. Since the arc rod 12 on the arc tube 11 is stuck in the first photography guide rail 5, the arc tube 11 cannot move. At this time, the outer slide rail 14 drives the gear 24 to rotate through the teeth 16. The gear 24 drives the first rotating shaft 20 to rotate through the second rotating shaft 23, the second bevel gear 22, and the first bevel gear 21 in sequence, causing the first rotating shaft 20 to wind the connecting rope 27, pulling the connecting rope 27 to pull the arc rod 12, so that the arc rod 12 retracts into the arc tube 11 and compresses the spring 26 until the arc rod 12 is no longer inserted into the first photography guide rail 5; At this time, since the arc rod 12 is no longer stuck in the first photography guide rail 5, the arc tube 11 can move forward. The spring 26 resets and drives the arc rod 12 to move backward and gradually extend out of the arc tube 11. The arc rod 12 drives the first rotating shaft 20 to rotate reversely through the connecting rope 27. The first rotating shaft 20 drives the gear 24 to rotate reversely through the first bevel gear 21, the second bevel gear 22, and the second rotating shaft 23, causing the gear 24 to move along the teeth 16, so that the arc tube 11, the U-shaped slider 10, the 360-degree camera 8, and the fill light 13 move synchronously to the second photography guide rail 6; At this time, the arc rod 12 abuts against the outer wall of the second photography guide rail 6. Move the outer slide rail 14 again. Since the arc rod 12 is stuck on the outer wall of the second photography guide rail 6, the arc tube 11 cannot move. At this time, the outer slide rail 14 drives the gear 24 to rotate through the teeth 16. The gear 24 drives the first rotating shaft 20 to rotate through the second rotating shaft 23, the second bevel gear 22, and the first bevel gear 21 in sequence, causing the first rotating shaft 20 to wind the connecting rope 27, pulling the connecting rope 27 to pull the arc rod 12, so that the arc rod 12 retracts into the arc tube 11 and compresses the spring 26, At this time, the arc rod 12 is no longer stuck on the outer wall of the second photography guide rail 6, and the arc tube 11 can continue to move forward into the notch 3 of the second photography guide rail 6. At this time, the spring 26 resets and drives the arc rod 12 to move backward and gradually extend out of the arc tube 11, and insert into the second photography guide rail 6, fixing the arc tube 11 at the notch 3 of the second photography guide rail 6, thereby fixing the 360-degree camera 8 and the fill light 13 on the second photography guide rail 6, and thus getting closer to the item on the photography table 1; The first electric slider 32 drives the 360-degree camera 8 and the fill light 13 to rotate around the item through the outer slide rail 14, the U-shaped slider 10, and the support Ⅰ9 in sequence.
