Description

Technical Field

[0001] The utility model relates to the technical field of rotating swing arms, in particular to a positioning and resetting structure of a rotating swing arm of a camera. Background Art

[0002] A camera swing arm is a device used to mount and adjust the position of a camera. It typically consists of a swing arm body made of metal or high-strength plastic, a precision rotary joint that enables horizontal and vertical rotation, and a mounting interface that connects the camera to a fixed bracket.

[0003] The initial and end positions of the existing camera rotating swing arm are fixed with magnets. The swing arm simply rotates on the base, and the user needs to manually move the swing arm to swing it. When the swing arm swings, the magnet at the initial position is detached. After the swing arm swings to the end position, it is attracted by the magnet at the end position to achieve positioning. However, this method requires the user to manually move the swing arm throughout the entire process, and the positioning points are only the initial and end positions, which makes it difficult to achieve positioning at any position and difficult to achieve automatic positioning of the swing arm.
