firstly, when unlocking, a consumer logs in a user by using a mobile phone APP interface and sends a login application to a monitoring management platform, an identity verification unit performs identity verification, and the login application passes verification; a consumer scans the two-dimensional code on the surface of the shell 1 and quickly establishes wireless connection, then inputs a pre-received sealed dynamic code on a mobile phone APP for authority verification, and an unlocking authority verification unit performs unlocking authority verification; after passing the inspection, the consumer can insert the unlocking needle into the needle hole 103, push the locking block 3 backwards to separate the locking block 3 from the two conductive insertion rods 22, and then pull out the locking rope 2 to complete unlocking; if the unlocking is not carried out through the verification, the alarm signal processing module generates an alarm signal and reports the alarm signal to the monitoring management platform for warning.

When locking, directly insert two electrically conductive inserted bars 22 into the casing 1, until the first inclined plane 34 contacts with the second inclined plane 222, and finally push the locking piece 3 to move backwards, the elastic piece 5 compresses synchronously, when the locking notch 31 aligns with the locking groove 221, the locking piece 3 moves forwards by the stretching force of the elastic piece 5, so that the locking portion 33 is clamped into the locking groove 221, and the electrically conductive inserted bar 22 is connected with the electrically conductive terminal 4, completing locking, and at the same time, the locking rope 2 enters into the power-on working state.

When the locking rope 2 is cut off, the alarm signal processing module can also generate an alarm signal and report the alarm signal to the monitoring management platform for warning.
