[0007] Furthermore, the fixing assembly includes a fixing platform, and the fixing platform is fixedly connected to the upper surface of the base.

[0008] Furthermore, a cylinder is fixedly connected to the upper surface of the fixed platform, and a sliding platform is fixedly connected to the output end of the cylinder.

[0009] Furthermore, a slide rail is fixedly connected to the upper surface of the fixed platform, and the slide platform is slidably connected to the inside of the slide rail.

[0010] Furthermore, a turntable 1 is fixedly connected to the upper surface of the slide, and a connecting rod is rotatably connected inside the turntable 1.

[0011] Furthermore, a plurality of turntables 2 are fixedly connected to the upper surface of the fixed table, and a rotating plate is rotatably connected to the side wall of the turntable 2.

[0012] Furthermore, a second slide groove is provided inside the rotating plate, and one end of the connecting rod is slidably connected inside the second slide groove.

[0013] Furthermore, a connecting shaft is rotatably connected inside the turntable 2, and a cover plate is fixedly connected to the outer wall of the connecting shaft.

[0014] The utility model has the following beneficial effects:

[0015] In the utility model, firstly, the motor drives the rotating rod to rotate so that the sliding column can slide inside the sliding frame, thereby making the connecting platform repeatedly slide inside the sliding groove and flip through the rack and the gear fan. In this process, the image capture angle and range of the camera can be changed.

Peaceful physical fitness. When the camera needs to be covered and blocked from light, the cylinder 12 is started. The cylinder 12 outputs a push-pull force on the slide 14 to drive the slide 14 to slide inside the turntable 15. While the slide 14 slides, it drives the turntable 15 on its top to move synchronously, so that the connecting rod 16 inside the turntable 15 rotates and changes its own inclination angle. While the connecting rod 16 rotates, it pulls the rotating plate 17. The rotation of the rotating plate 17 on the side wall of the turntable 2 19 can drive the connecting shaft 20 to rotate inside the turntable 2 19, so that the cover plate 21 changes its inclination angle to block the camera. This process enables the device to adapt to a variety of environments to cover the light source to prevent reflections from affecting picture capture, thereby ensuring the image recognition effect.
