Metal material stab-proof layers are widely used due to their good stab-proof performance, but the traditional metal stab-proof layer structure has many shortcomings. For example, although the single-layer whole piece structure has good stab-proof performance, it cannot be bent, which affects the flexibility and comfort of wearing; although the single-layer multi-piece overlapping structure can improve the bending performance, the overlapping seam has poor anti-oblique stab effect, and it can only be bent in one direction after wearing, and there will be abnormal noise during activities; although the multi-layer overlapping structure has good anti-stab and anti-oblique stab effects, it can only be bent in one direction, and is heavy and thick. The non-metallic multi-layer overlapping structure has the problems of high material cost, thick finished product and large weight. Utility Model Content
