[0002] An action camera is a small, portable digital camera designed for extreme sports or outdoor activities. It is usually waterproof, shockproof, and high-temperature resistant. It can shoot stably in various extreme environments. It is often equipped with a wide-angle lens and can record high-quality videos and photos. It is suitable for mountaineering, skiing, diving and other sports. The design of action cameras focuses on easy fixation and carrying. They can usually be used in conjunction with special accessories, selfie sticks and other body devices. They are widely used to record adventure and sports scenes.

[0003] The prior art lacks a multifunctional and flexible body-mounted device that can fix the action camera at different positions of the user. When the user needs to take a selfie, the action camera needs to be fixed to the selfie stick. When the user needs to shoot from a first-person perspective, the action camera needs to be fixed to the chest strap. When the user needs multiple shooting needs, he needs to carry multiple sets of body-mounted devices, which means that the user needs to carry multiple separate fixing devices to meet different shooting needs, which increases the carrying burden and the complexity of use. Each time the equipment is changed, it may take time to adjust, which reduces the convenience and efficiency of shooting. In addition, multiple body-mounted devices are also prone to cause confusion and unnecessary additional costs, affecting the user experience. Summary of the invention
