[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-6 An anti-loss device that can be fixed to an item includes a central shell 1. The central shell 1 serves as the main support structure of the anti-loss device and is made of plastic material with certain strength and toughness, providing a stable installation space for internal components. Both the upper and lower ends of the central shell 1 are provided with outer shells 3, which are connected to the central shell 1 via snap-fit ​​connections. This snap-fit ​​connection method facilitates quick installation and removal of the outer shells 3 while ensuring a tight connection between the outer shells 3 and the central shell 1. An annular groove 2 is provided on the outer side of the central shell 1. The annular groove 2 allows for secure mounting when the item is stored. The rubber band 5 is wrapped around the annular groove 2 to prevent the anti-loss device from being too messy. The rubber band 5 is fixedly connected to the left side of the central shell 1. The rubber band 5 has good elasticity and extensibility and can be stretched appropriately according to the size of the fixed item, thereby enhancing the connection stability between the anti-loss device and the item. The key ring 6 is fixedly connected to the left side of the rubber band 5. The upper end of the central shell 1 is provided with an insertion groove 12. The right side of the insertion groove 12 is provided with an insertion hole 9. The insertion hole 9 is elliptical.
