An anti-counterfeiting structure to prevent tampering or replacement of the authenticated product of a packaging box includes a fixing member, a connecting member, a first mounting member, a second mounting member, and an anti-counterfeiting member. The connecting member connected to the fixing member defines a first receiving groove. The first mounting member is disposed in the first receiving groove and defines a second receiving groove. The anti-counterfeiting member in the second receiving groove includes an electronic screen and a battery disposed on the electronic screen. The first mounting member can be readily moved along a first direction away from the connecting member, driving the electronic screen along the first direction and thereby separating the battery from the electronic screen, causing cancellation of the structure and the visible authenticity of the product within the packaging box.
