When shopping in supermarkets or buying clothes in daily life, people may notice that when making payments, the cashier holds a cylindrical object and places it on the anti-theft hard label of the product. The label opens, and many people don't know what it is. In fact, it is a hard label nail remover. So how does it easily open the anti-theft magnetic buckle?

It is mostly composed of a buckle and a nail. The nail rod has two pairs of small grooves. When the nail is inserted from the bottom of the anti-theft magnetic buckle, several small steel balls in the buckle will slide to the position of the grooves on the nail; And the iron rings on top of the steel balls firmly clamp them in the grooves under the pressure of the top spring. In this way, it is impossible to pull the nail out from the bottom with ordinary brute force, and the role of the label nail remover becomes apparent.

The hard label nail remover of supermarket anti-theft device manufacturers is generally composed of a magnetic ring and a magnetic core, which combine to form an eddy current magnetic force. The magnetic force is concentrated at the center of the nail remover, and the tension formed can reach 8500GS. Generally, domestic magnetic buckles can be opened with a force of 4500GS, but some customers' specially customized strong anti-theft hard labels require a force of 1200GS to open. At this time, the corresponding strong nail remover needs to be used to remove the label. Do you have new knowledge about label nail remover now!
