When the rubber plug 307 needs to be removed, the connecting sleeve 301 is rotated to move away from the mounting sleeve 22, and the sealing box 302 moves upwards at this time, so that the first spring 308 and the second spring 309 recover, the elasticity of the mounting plate 306 disappears, and the connecting sleeve 301 and the sealing box 302 can be lifted upwards to drive the rubber plug 307 to be pulled out of the bottle neck 12. When the rubber stopper 307 is sucked by the vacuum effect generated in the bottle body 1, the mounting sleeve 22 may be rotated so that the mounting sleeve 22 moves upward, thereby pressing the connection sleeve 301 upward, and the rubber stopper 307 is pushed upward. Meanwhile, when the bottle body 1 is smaller, due to the fact that a certain weight exists in the whole body of the connecting structure 2 and the sealing assembly 3, after the bottle body 1 is installed, the installation sleeve 22 can be rotated and taken down when the bottle body 1 is used, and the bottle body 1 is prevented from toppling in the using process.

The above-described embodiment is only one alternative embodiment of the present utility model, and many alternative modifications and combinations of the above-described embodiment may be made by those skilled in the art based on the technical solutions of the present utility model and the related teachings of the above-described embodiment.
