Description

TECHNICAL FIELD

[0001] The utility model relates to a commodity anti-theft device, in particular to a single rope slack alarm spider label, which is suitable for the anti-theft of small box products or blister products in retail stores. BACKGROUND

[0002] The prior application 202420749800.2 of the applicant discloses a commodity anti-theft device, which comprises a first half shell, a PCB assembly, a steel wire rope assembly, a second half shell and a lock core assembly. The PCB assembly is arranged in a shell formed by the first half shell and the second half shell. The steel wire rope assembly comprises a copper buckle, two lead wires and a steel wire rope. The fixed end of the steel wire rope is arranged in the shell. The fixed end is provided with the copper buckle and the two lead wires. The two lead wires are electrically connected to the PCB assembly to form an electronic circuit. The free end of the steel wire rope passes through the lock core assembly. The part of the steel wire rope outside the shell forms a circular ring and is bound to the protected commodity. When the steel wire rope is cut, the circuit is disconnected, which triggers the alarm of the PCB assembly. The lock core assembly is provided with a rope slack knob. The rope slack knob can be actuated to make the steel wire rope retract backward to slacken the rope.

[0003] The prior patent application has a problem that the free end of the steel wire rope assembly is exposed outside the shell. If the protected commodity has a small volume, in addition to the steel wire rope bound to the commodity, the other long steel wire rope is exposed outside the shell. Although the steel wire rope can be clamped on the buckle, the excess steel wire rope and the buckle will reduce the utilization rate of the retail space and cause disorderly arrangement.
