Specifically, a positioning support rod 6 is fixed to the bottom of the inner wall of the clamp seat 2 , and the pin surface of the tripod body 1 is movably connected to the arc-shaped notch at the top of the positioning support rod 6 . The positioning support rod 6 is used to position the tripod body 1 .

In this embodiment, please refer to Figures 1 and 5. There are two positioning support rods 6. Two of the pins of the tripod body 1 are fitted on the top of the positioning support rod 6. At the same time, the side of the positioning support rod 6 is fitted with the side of the tripod body 1. The positioning support rod 6 is used to position the tripod body 1 to prevent the tripod body 1 from moving on the horizontal plane.

Specifically, a positioning plate 306 movably connected to the inner wall of the tripod shaft body 1 is fixed on the top of the support plate 303 , and the positioning plate 306 is used for positioning the tripod shaft body 1 in the horizontal direction.

In this embodiment, please refer to Figures 2 and 4. When the tripod body 1 is placed on the support plate 303, the positioning plate 306 is in contact with the inner wall of the tripod body 1, and the positioning plate 306 is used to position the tripod body 1 in the horizontal direction to prevent the tripod body 1 from being misaligned with the support plate 303 and the splint 301.

Specifically, a guide surface is provided at a corner position on the top of the positioning plate 306 , and the guide surface is used for guiding the tripod shaft body 1 when it is placed on the supporting plate 303 .

In this embodiment, please refer to Figures 2 and 4. When the tripod body 1 is placed on the support plate 303, it is affected by the inclined surface of the guide surface, which makes it convenient for the tripod body 1 to be sleeved on the positioning plate 306 and for the tripod body 1 to be stably placed on the support plate 303.

Specifically, a round rod 5 is fixed to the bottom of the support plate 303 , a dial plate 4 is provided below the clamp seat 2 , and the bottom of the round rod 5 passes through the support seat 302 and the clamp seat 2 in sequence and is fixedly connected to the top of the dial plate 4 .
