The utility model provides a clamping piece, a buckle body, an anti-fake buckle structure and a packaging box, and the clamping piece comprises a second bayonet which can be clamped with a corresponding buckle body; and the side surface of the second bayonet can be in surface contact with the buckle body so as to form limiting. According to the utility model, the side edge of the bayonet is designed to be in surface contact with the buckle body, so that the contact area with the buckle body is increased, and the buckle body is difficult to damage by cutting the bayonet by pulling the clamping piece back and forth. 本实用新型提供了一种卡合件、卡扣本体、防伪卡扣结构及包装盒，卡合件包括第二卡口，能够与对应的扣体相卡合；第二卡口的侧面能够与所述扣体面接触，从而形成限位。本实用新型通过将卡口的侧边设计为与扣体能够面接触，从而增加与扣体的接触面积，从而难以通过来回拉动卡合件来使卡口切割损坏扣体。
