step three: adjusting a limiting structure to enable two adjacent conveying pipes to be sealed through a collision sealing structure, sealing the conveying pipes and the conversion pipes through the sealing structure, clamping a sealing sleeve in the vacuum chamber on the conveying pipes, firstly connecting a first fixing sleeve with the conveying pipes in a threaded manner, then clamping the first fixing sleeve with a second fixing sleeve through a vice, connecting the second fixing sleeve with the conveying pipes or the conversion pipes in a threaded manner, clamping teeth of the vice with a clamping groove, screwing the first fixing sleeve or the second fixing sleeve, rotationally connecting the first fixing sleeve with the second fixing sleeve through a connecting sleeve, further driving the two adjacent conveying pipes or the conveying pipes and the conversion pipes to move relatively, and simultaneously connecting the two positioning sleeves in a sliding manner to enable the two adjacent conveying pipes or the conveying pipes and the conversion pipes to be sealed through the sealing sleeve in a collision manner, oil is conveyed from the interior of the infusion chamber, and meanwhile, the connecting sleeve and the first fixing sleeve are abutted against the sealing ring to perform secondary sealing on the conveying pipe and the conversion pipe;
step four: the vacuum chamber is connected to the air valve through vacuum equipment, the interior of the vacuum chamber is vacuumized, then the dustproof sleeve is screwed, the dustproof sleeve seals the thread on the conveying pipe, the adjusting rod is screwed, the baffle is enabled to abut against the conveying pipe or the conversion pipe, and the positioning sleeve is limited.
