The effects achieved by the above components are: By setting the adjusting toothed plate 41, the movement of the bracing plate 42 can be controlled. By setting the adjusting toothed plate 41 and the bracing plate 42, the adaptability of the bracket to different sites can be improved. By setting the adjusting gear 44, the movement of the adjusting toothed plate 41 can be conveniently controlled. Arc plates 43 are fixedly connected to one sides of the three support legs 2 close to the adjusting gears 44, the arc plates 43 are rotatably connected to the adjusting gears 44, and a grip 45 is fixedly connected to one side of the adjusting gear 44 away from the arc plate 43. The effects achieved by the above components are: By setting the arc plate 43, the adjusting gear 44 can be installed on the support leg 2. By setting the grip 45, the rotation of the adjusting gear 44 can be conveniently controlled.

[0033] The upper surfaces of the three support legs 2 are fixedly connected with mounting plates 46, and the inner walls of the mounting plates 46 are threadedly inserted with first threaded rods 47. The effects achieved by the above components are as follows: By providing the mounting plates 46, the first threaded rods 47 can be installed, and the first threaded rods 47 threadedly inserted in the inner walls of the mounting plates 46 can rotate. One end of the first threaded rod 47 close to the adjusting toothed plate 41 is fixedly connected with a connecting plate 48, and a cushion plate 49 is adhesively connected to the side of the connecting plate 48 away from the mounting plate 46. The effects achieved by the above components are as follows: By providing the connecting plate 48, the cushion plate 49 and the first threaded rod 47 can be connected, and by providing the connecting plate 48 and the cushion plate 49, the position of the adjusting toothed plate 41 can be restricted.

[0034] Referring to Figure 2 and Figure 4 and Figure 5 As shown, specifically, the rotating device 5 includes three rotating beads 51. The three rotating beads 51 are fixedly connected to one end of the adjusting toothed plate 41 close to the support leg 2, and the three rotating beads 51 are rotatably connected to the inner wall of the abutting plate 42. The upper surface of the abutting plate 42 is fixedly connected with a rectangular plate 52. The effects achieved by the above components are as follows: By providing the rotating beads 51, the angle of the abutting plate 42 can be rotated, so as to better adapt to the support work on different sites.

[0035] The inner wall of the rectangular plate 52 is threadedly inserted with a second threaded rod 53, and one end of the second threaded rod 53 close to the adjusting toothed plate 41 is rotatably connected with a moving plate 54. The effects achieved by the above components are as follows: By providing the first threaded rod 47, the moving plate 54 can be installed, and at the same time, it is convenient to control the movement of the moving plate 54. A rubber pad 55 is adhesively connected to the side of the moving plate 54 away from the second threaded rod 53, and a sliding rod 56 is slidably connected to the inner wall of the rectangular plate 52.

The effects achieved by the above components are as follows: By providing the sliding rod 56, it can be ensured that the moving plate 54 will not rotate during the movement of the moving plate 54.

[0036] Working principle: when using the bracket, the camera is installed on the support rod 1 through the mounting platform 3, and the support rod 1 is fixed by the support leg 2. When the support leg 2 needs to be supported by the support plate 42, the first threaded rod 47 is rotated to rotate on the inner wall of the mounting plate 46, thereby controlling the connection plate 48 and the pad 49 to move away from the adjustment tooth plate 41, and the restriction on the position of the adjustment tooth plate 41 is released. Then, the handle 45 is grasped to control the adjustment gear 44 to rotate on the surface of the arc plate 43, so that the position of the support plate 42 is adjusted by the adjustment tooth plate 41. After the adjustment is completed, the first threaded rod 47 is rotated to make the connection plate 48 and the pad 49 move close to the adjustment tooth plate 41, and the position of the adjustment tooth plate 41 is restricted. By setting the adjustment device 4, when the bracket is used to support the camera on an uneven site, the support leg 2 can be supported by adjusting the adjustment tooth plate 41, thereby improving the stability of the camera installation and the flexibility of the bracket.

[0037] When the angle of the butt plate 42 needs to be adjusted, the second threaded rod 53 is first rotated to make it rotate on the inner wall of the rectangular plate 52, thereby controlling the shifting plate 54 to drive the rubber pad 55 away from the adjusting tooth plate 41, and then the angle of the butt plate 42 is adjusted by using the rotating ball 51. After the adjustment of the butt plate 42 is completed, the second threaded rod 53 is rotated to drive the shifting plate 54 to move closer to the adjusting tooth plate 41 to limit the rotation of the butt plate 42. During the movement of the shifting plate 54, the sliding rod 56 slides on the inner wall of the rectangular plate 52 to prevent the shifting plate 54 from rotating. By setting the rotating device 5, when the butt plate 42 is used to support the support leg 2, the angle of the butt plate 42 can be adjusted according to the ground conditions, thereby improving the fit between the butt plate 42 and the ground, improving the stability of the support of the butt plate 42, and ensuring the effect of the butt plate 42 supporting the support leg 2 as much as possible.
