[0046] Then, the lower pressing rod 27 is manually pulled, the lower pressing rod 27 drives the pressing connecting rod I 14 connected thereto to rotate around the rotating shaft I 13, since the outer sides of the two pressing connecting rod I 14 are meshed and connected with each other, synchronous swinging is realized, the pressing connecting rod I 14 drives the pressing connecting rod II 15 to swing, the pressing connecting rod II 15 drives the lower pressing block 17 to move downwards through the rotating shaft II 16, the lower pressing block 17 drives the connecting block 18 and the vacuum pressing cap 19 at the bottom to move downwards, the sealing rubber ring 22 at the bottom of the vacuum pressing cap 19 contacts and tightly seals the tank opening of the liquid storage tank 11;
