pressing bodies

310 and 320 to approach or separate from each other. When the two are close to each other and closely contacted, a sealed cavity is formed between the first press-fitting body 310 and the second press-fitting body 320, when the vacuum operation of the packaging bag in the sealed cavity is required, the vacuum-pumping assembly 340 is started to perform the vacuum-pumping operation on the sealed cavity, and when the vacuum-pumping operation is finished, the first press-fitting body 310 and the second press-fitting body 320 are controlled to be separated from each other through the action of the second driving member 330 so as to prepare for the vacuum-pumping of the next packaging bag.
