[0004] In the above document, an external rotating motor is used to drive the rotating gear to rotate, thereby driving the camera to move. In this way, too many components are located in the external environment, and there are certain requirements for the stability of the external environment. The stability of the camera is more important during monitoring, and the structure of the camera should be kept as stable as possible when it is not moving. The above document uses a servo motor to stabilize the position of the camera, but the cost of the components is high and the subsequent maintenance is also more troublesome.

During the continuous rotation of the output shaft, the positioning plate 603 can be brought out, and the compression spring 605 can be stretched at the same time. After the positioning plate 603 rotates, it can be clamped in the next clamping groove. After the power motor 601 stops outputting power, the positioning plate 603 is statically clamped on the bottom ring seat 602, thereby limiting the rotation of the output shaft, and also limiting the self-rotation of the split shell 1.

When in use, the tightening bolt 401 presses the tensioning frame 402, so that the tensioning plate tightly connects the head shell 101, the middle expansion shell 102 and the tail shell 103 together, and the limiting ring plate 403 on the tightening bolt 401 plays a major tightening role, and the limiting convex ring 404 on the limiting ring plate 403 can also play a role in stabilizing the position of the tensioning plate, and the split tensioning plate can be easily disassembled. When disassembly is required, the tightening bolt 401 is rotated to make the tightening bolt 401 penetrate into the tail shell 103, and then the two parts of the tensioning plate are pulled up and down respectively.

When external functional expansion is required, additional functional modules can be installed on the expansion interface, and the additional functional modules can be reinforced through the connecting holes. The protruding platform 801 on the first partition plate 8 can be embedded in the corresponding docking hole 902 on the second partition plate 9, thereby improving the stability between the components and avoiding misalignment between the components. During disassembly, the snap-on spring clip 901 can play a temporary fixing role to prevent the components from being scattered after the tightening mechanism 4 is lost.
[0039] When the shooting angle needs to be rotated, the output shaft of the power motor 601 rotates. During the rotation, since the output shaft is clamped in the clamping rod, after the power motor 601 is started, it can drive the split shell 1 to rotate, and at the same time drive the positioning plate 603 to rotate. The positioning plate 603 is clamped on the bottom ring seat 602 by the pulling effect of the pressing spring 605. During the continuous rotation of the output shaft, the positioning plate 603 can be brought out and the pressing spring 605 can be stretched. After the positioning plate 603 rotates, it can be clamped in the next clamping groove. After the power motor 601 stops outputting power, the positioning plate 603 is statically clamped on the bottom ring seat 602, thereby limiting the rotation of the output shaft and also limiting the rotation of the split shell 1 itself. When the height of the shooting range needs to be adjusted, the adjusting ring block 304 is rotated to change the position of the adjusting cylinder 303 on the central shaft 302, thereby pushing or pulling the limit rod 306 to move. After the limit rod 306 moves, it can drive the bearing seat 301 to rotate, thereby changing the shooting range.
[0040] When in use, the tightening bolt 401 presses the tensioning frame 402, so that the tensioning plate tightly connects the head shell 101, the middle expansion shell 102 and the tail shell 103 together, and the limiting ring plate 403 on the tightening bolt 401 plays a major tightening role, and the limiting convex ring 404 on the limiting ring plate 403 can also play a role in stabilizing the position of the tensioning plate, and the split tensioning plate can be easily disassembled. When disassembly is required, the tightening bolt 401 is rotated to make the tightening bolt 401 penetrate into the tail shell 103, and then the two parts of the tensioning plate are pulled up and down respectively.
