An annular step is arranged on the inner plug piece, and a fracture space can be formed between the annular step and the fracture clamping table. The fracture clamping table of the rotation stopping sleeve body extends into the end of the inner cavity of the drainage sleeve through the through hole and can be connected with a bottle neck in the inner cavity of the drainage sleeve in a clamped mode, and the drainage sleeve and the rotation stopping sleeve are made of different materials. Due to the material characteristics of higher hardness and strength, the bottle neck is clamped and locked more firmly by the fracture clamping table on the rotation stopping sleeve, and the bottle neck can be damaged or even broken by forcibly pulling the cap, so that the wine bottle cannot be reutilized, and the anti-counterfeiting purpose is achieved.
