Under the action of the thread, the movable plate 6 and the scraper 5 will be driven to slide upward, and the gear 11 will be driven to reverse at the same time. Under the meshing action with the tooth plate 10, the baffle plate 9 will be driven to slide out from the inner side of the receiving groove 8 until the baffle plate 9 drives the sealing gasket 12 to press against the inner side of the leakage groove 7. At this time, the blocking of the leakage groove 7 is completed.
