Anti-misoperation quick pressing plate sealing device

The invention discloses an anti-misoperation rapid pressing plate sealing device which comprises a sealing unit, a double-layer disc rotating assembly connected with a plug-in type protection pressing plate in a sleeving mode, a multi-positioning assembly connected with the double-layer disc rotating assembly in an inserted mode and partially arranged in the double-layer disc rotating assembly, and an opening and closing prompting assembly partially arranged in the double-layer disc rotating assembly. And the opening and closing positioning assembly is connected with the double-layer disc rotating assembly. The device has the beneficial effects that the protection pressing plates in different shapes in the opening and closing states can be sealed through the sealing unit, mistaken touch is avoided, and the applicability is high; the pressing plate is primarily positioned through the double-layer disc rotating assembly, sealing stability is guaranteed through secondary positioning of the multi-positioning asse
