s2, when the differential progressive limiting device is used, the position of the differential progressive limiting device is read through a PCB, information is fed back to a database through a communication chip, and the information is compared with initial position information of the differential progressive limiting device when a product originally stored in the database leaves a factory, so that whether the differential progressive limiting device is triggered and moves is known;
s21, when a product leaves a factory, the differential progressive limiting device and the gear toggle switch of the initial passive memory snap device are arranged at a first position, the snap is pressed for the first time, the differential progressive limiting device is pushed to move forwards by the snap hook structure, the differential progressive limiting device is arranged at a second position, at the moment, the spring is compressed, the supporting structure and the second-level single teeth are relatively displaced, the front end of the differential progressive limiting device pushes the gear toggle switch to move forwards, the snap hook is loosened, the spring is restored to be original, the snap hook is driven to move backwards by the spring seat, at the moment, the snap hook structure is moved towards the adjacent rear-side single tooth on the first-level single tooth of the differential progressive limiting device, and the gear toggle switch is arranged at the second position;
s22, pressing the elastic buckle again, wherein the elastic buckle pushes the differential progressive limiting device to continue to move forwards through the hook structure, at the moment, the differential progressive limiting device is at a third position, the spring is compressed again, the supporting structure continues to move relatively to the second-stage single teeth, the front end on the differential progressive limiting device pushes the gear toggle switch to move forwards further, the elastic buckle is loosened again, the spring is restored to the original state again, the elastic buckle is driven to move backwards again through the spring seat, at the moment, the hook structure of the elastic buckle continues to move to the adjacent rear-side single teeth on the first-stage single teeth of the differential progressive limiting device, and the gear toggle switch is located at the third position unchanged;
s23, after the product leaves a factory by using the passive memory snap device, pressing the snap, enabling a gear toggle switch to be at a second position, enabling a consumer to supply power to the passive memory snap device, automatically detecting the position of the gear toggle switch by a safety chip on a PCB, reporting a cloud background database through a communication chip, enabling the consumer to communicate with an anti-counterfeiting package through handheld wireless communication equipment if the gear toggle switch is at a normal second position, verifying a cloud encryption dynamic code if the gear toggle switch is at a third position, judging that the product is at an abnormal position, enabling the snap representing the passive memory snap device to be pressed again, enabling the safety chip on the PCB to be self-destroyed, and automatically closing the commodity identity ID and the information data queue.
