The anti-theft device for commodities also includes rotor 1 and the permanent magnet 2 being arranged on rotor 1, the rotor 1 and the lock
Structure is connected, and the lock construction activity can be driven when rotor 1 rotates in one direction to lockset position of coupler；The commodity are prevented
Steal and be additionally provided with location division 30 on the outside of device, to position lockaid gun 200.
The location division 30 can be the portion that can be positioned or be limited its position with dual lock device 200 on anti-theft device housing
Position.So that permanent magnet 2 is in caused by lockaid gun in alternating magnetic field, and rotate.
The location division 30 can be formed on the housing of anti-theft device, and the housing is made up of upper casing 31 and lower casing 32,
Preferably, the location division 30 is the projection on lower casing, and the permanent magnet 2 in the rotor 1 is at least partially located at the convex portion 30
It is interior.
Preferably, rotor 1 is rotated by axle of lock construction, can reduce the volume of anti-theft device, simplifies structure.It is described
Lock construction is provided with axle portion 41 and forced section 42, and the rotor is enclosed on outside the axle portion 1 of lock construction and rotated in one direction
When the forced section 42 is acted on and drives the lock construction activity to lockset position of coupler.The rotor 1 is annular element, its center
Hole 10 and the axle portion 41 of the lock construction are rotatablely connected.
The rotor 1 is annular element, and the permanent magnet 2 is arranged on the outside left of rotor 1.The permanent magnet can be
Permanent magnetic ring or some pieces of permanent magnet blocks composition, if polylith permanent magnet block forms, it most preferably can be relative to turning
The pivot concentric uniform arrangement of son 1.
In the present embodiment, the lock construction can use the lock construction of conventional pinning bar, and the lock construction includes can axle
Active lock core print seat 4 forwards, backwards, more lock core pearls 5 are set on the lock core base 4, are provided with outside lock core base 4 with nail rod hole
Taper bowl 6, so that the jam-packed of lock core pearl 5 is clamped into the nail rod of insertion in upper lock position at lock construction, the resetting structure
