Either side of the snap-fitting opening 12 is rotatably connected to one end of the hinge 111, and an elastic return member 112, such as a retaining spring, is installed at the rotation position, and the other end of the hinge 111 is snapped to the inner side of the snap-fitting opening 12; the first connecting structure 1 is also provided with an active space 13 for realizing the rotation of the hinge 111 around the inner side of the snap-fitting opening 12. Exemplarily, the first connecting structure 1 can be a lock structure of an existing anti-lost key chain device, by designing part of the closed area to be hinged and openable. For example, when the anti-lost key chain device is fastened to the user's waistband, the hinged part is moved to create a gap in the closed area, allowing the trouser loop of the user's waistband to enter the closed area. The hinged part is reset by a reset spring, so that the closed area is reclosed, completing the buckling of the anti-lost key chain device on the user's waistband.

[0057] The prompt component 2, the first connecting structure 1 and the prompt component 2 are detachably connected;

[0059] The telescopic assembly 4 is connected to the first connecting structure 1 and the second connecting structure 3 respectively. The second connecting structure 3 can be movably telescopic relative to the first connecting structure 1 through the telescopic assembly 4 .

[0060] During use, since the anti-lost key chain device is buckled on the trouser loop of the user's belt, the user pulls the second connecting structure 3 away from the first connecting structure 1, and then aligns the object on the first connecting structure 1, such as a key, with the door lock or other lock to unlock it. After unlocking, the control of the second connecting structure 3 is released, and the second connecting structure 3 is automatically reset to the side close to the first connecting structure 1 under the reset force of the telescopic component 4. During use, there is no need to unbuckle the anti-lost key chain device from the user's belt, which is convenient and quick.
