A support shaft 10 is horizontally placed on the support plate 9, and the support shaft 10 is rotatably connected to the support plate 9. A camera 12 is installed on the support shaft 10, and two U-shaped frames 11 are fixedly arranged between the camera 12 and the support shaft 10. Both U-shaped frames 11 are arranged radially along the support shaft 10, and the camera 12 is located within the array circumference of the vertical rod.

[0023] A linkage component is provided between the turntable 5 and the mounting plate 1. The linkage component is connected to the support shaft 10 to drive the support shaft 10 to rotate.

[0024] The linkage assembly includes a first bevel gear 2 and a second bevel gear 7. A connecting shaft is fixedly installed at the bottom of the mounting plate 1, and the connecting shaft is coaxial with the turntable 5. The first bevel gear 2 is fixedly sleeved on the connecting shaft.

[0026] Two connecting rods 8 are welded and fixed on the rotating shaft, and both connecting rods 8 are arranged radially along the rotating shaft. The two connecting rods 8 and the rotating shaft form a U-shaped transmission structure. An eccentric shaft is fixedly installed at the end of each connecting rod 8 away from the rotating shaft. Each eccentric shaft is parallel to the rotating shaft, and the two eccentric shafts are coaxial.

[0027] Two eccentric shafts correspond one-to-one with two loop frames 11. Each eccentric shaft is inserted into the corresponding loop frame 11 and is in a limited sliding fit with the corresponding loop frame 11.
