Embodiment

The technological means adopting for real the purpose of this utility model is: a kind of novel electron pocket anti-theft device, wireless launcher is positioned at fixed head, with the wireless receiving alarm pairing in fixed card, transmission of signal mutually, in the time that wireless receiving alarm and wireless launcher are separated by beyond 3 meters, electronic chip in wireless receiving alarm is responded to, and sends sound signal, after amplifier amplifies signal by the loudspeaker alarm sound that sets out; It is characterized in that: it is made up of fixed head, over cap, safety pin, fixing chain entrance, fixing chain draw-in groove, fixed card and button; Described fixed head is rectangular structure, and upper end face is provided with safety pin draw-in groove, and inside is provided with wireless launcher; Described over cap is positioned at fixed head upper end side, fixed head by gemel connection; Described safety pin is positioned at fixed head upper end face; Described fixing chain entrance is positioned at fixed head outer surface; Described fixing chain draw-in groove is positioned at fixing chain entrance lower end, connects by chute, and its inside is provided with jump ring; Described fixed card one end connecting fixing chain, its inside is provided with wireless receiving warning device; Described button is positioned at fixed head dual-side, is symmetrical structure and distributes.

In the second embodiment described in Fig. 1, Fig. 2, over cap and fixed head upper end are connected; Fixing chain can insert by inlet slot, in chute slides down to draw-in groove, then is locked by jump ring; The inner wireless launcher that receives of fixed head, wireless launcher is connected with reset key.

In the 3rd embodiment described in Fig. 2, Fig. 3, Fig. 4, jump ring is positioned at draw-in groove, and its inside is symmetrical structure, and chuck is connected with connecting rod 1, is connecting spring in chuck lower end; Above connecting rod 1 two ends, connecting spring, the lower end connecting rod 3 that is being connected through the hinge; Connecting rod 3 is connecting the connecting rod 4 that is being connected through the hinge, and connecting rod 3 can slide in connecting rod 5 lower ends; Connecting rod 4 one end are connecting unlock key, and in the time pressing unlock key, the connecting rod 4 being connected with unlock key promotes forward, thereby connecting rod 3 one Slideslips rotate connecting rod 1, drive chuck to rotate, and jump ring is opened.

In the 4th embodiment shown in Fig. 2, Fig. 5, fixing chain one end is connecting fixed card, and fixed card can be connected with article, is provided with wireless receiving alarm in fixed card.
