The anti-pull handcuffs are formed by integral bending and die-casting. The lock cylinder is a triangle with an anti-shift cover, which significantly enhances the anti-shift coefficient. The handcuffs are composed of main parts such as outer cylinder, ball head, connecting shaft, connecting buckle, O-ring, lock cylinder, splint, and fan teeth. The surface of the handcuffs is bright and uniform in color, and the connecting parts are smooth and tidy.
