Embodiment 1

[0057] see Figure 1~3 , the locking device for commodity anti-theft includes a locking housing 3, a locking ball 8, a telescopic body 9, a locking return spring 10, a commodity connection unit, a traction body 5 and a sliding steel wire 4, and the upper part of the locking housing 3 The inner cavity is a locking cavity 12, and the cross section of the locking cavity 12 is trapezoidal; a plurality of locking balls 8 are arranged in the locking cavity 12; The lower side of the ball 8 and the upper part of the telescopic body 9 are provided with a locking ball holding mechanism; the locking return spring 10 is arranged inside the locking housing 3 on the lower side of the telescopic body 9; the slender commodity connection unit vertically passes through the locking Housing 3 and telescopic body 9, a plurality of locking balls 8 are evenly arranged around the commodity connection unit; traction body 5 is arranged under the locking housing 3 and is installed in the anti-theft hous...

Embodiment 2

[0063] see Figure 5 , The commodity connection unit includes an anti-theft steel wire 13, the upper end of the anti-theft steel wire 13 is a fixed end 14 relatively fixed to the locking housing 3, and the lower end is a free end 15. The fixed end 14 of the anti-theft steel wire 13 can be fixedly connected with the locking housing 3 to the anti-theft housing and the anti-theft housing.

[0064] The fixed end 14 of the anti-theft steel wire 13 is fixedly connected with a columnar body 16 , and the diameter of the columnar body 16 is larger than that of the anti-theft steel wire 13 . Two sliding steel wires 4 respectively pass through the locking housing 3 from both sides of the commodity connection unit, and the upper ends of the two sliding steel wires 4 are respectively connected to both sides of the telescopic body 9 . The directional sliding of the telescopic body 9 is guaranteed, and the work is stable and reliable. Other structures are the same as in Embodiment 1.

Embodiment 3

[0066] see Figure 6~7 , the locking housing 3 , the traction body 5 and the sliding steel wire 4 are all fixed inside the anti-theft housing 21 , and the commodity connection unit passes through the anti-theft housing 21 and the locking housing 3 .

[0067] In this embodiment, the commodity connecting unit is an anti-theft steel wire 13 as an example for illustration. The inside of the anti-theft housing 21 is provided with a fixed cavity for accommodating a columnar body 16, and the columnar body 16 of the anti-theft steel wire 13 is fixed in the fixed cavity. The two side walls of anti-theft housing 21 are provided with steel wire entrance and steel wire outlet respectively, and the free end 15 of anti-theft steel wire 13 penetrates in the anti-theft housing 21 by steel wire entrance and stretches out by steel wire outlet, and anti-theft steel wire 13 is in anti-theft housing 21. The inner side passes through the locking housing 3 and the telescopic body 9 at the same time....
