Abstract: An electronic anti-theft label of a nickel-titanium alloy temperature memory wire includes a first housing, a second housing with a boss, a locking beam, a locking catch, a rotating device, a nickel-titanium alloy temperature memory wire, and an unlocking device. The second coil on the unlocking device generates, after being energized, a magnetic field around. The second coil serving as a sending end is placed in a third groove, so that the first coil is induced to generate electricity by using the electromagnetic induction principle, and the first coil serves as a receiving end. The sending end sends an electromagnetic signal to the external environment under the action of electric power, and the receiving end receives the electromagnetic signal and converts the electromagnetic signal into current. The nickel-titanium alloy temperature memory wire is energized and heated to contract to drive the rotating device to move.

Abstract: A novel spider electronic tag includes a take-up device; and a base connected to the take-up device through a retractable steel wire rope. The take-up device includes: a housing; a take-up assembly, mounted in the housing; and a locking fastener, mounted in the housing and configured to lock the take-up assembly; the locking fastener includes: a rotating ratchet member, fixedly arranged at the top of the take-up assembly; and a leaf spring, embedded in an inner circumferential wall of the housing and configured to cooperate with the rotating ratchet member to lock the take-up assembly. The steel wire rope is passed in a listed sequence through the rotating ratchet member, the take-up assembly and the base clockwise from top to bottom, and two ends of the steel wire rope are fixed inside the rotating ratchet member, to connect the take-up device with the base.

Abstract: A pin-type anti-theft tag includes a safety pin, a tag body, a tag hole suitable for inserting the safety pin, at least one sensor, and a first lock body and a second lock body located in the tag body. Both the first lock body and the second lock body need to be located in a release position at the same time, so that the safety pin can be successfully removed from the tag body. The first lock body is mounted at an unlocking hole of the tag body, and a spring lock retainer is arranged at a lower portion of the first lock body. The second lock body is mounted below the tag hole of the tag body, and a pin rod of the safety pin is inserted into the second lock body along the tag hole to play a locking role.
