[0010] A plurality of adjusting bolts are arranged in a ring in the middle of the connector. The adjusting bolts pass through the connector wall, with their axes perpendicular to the connector axis and their length projections falling on the second sealing part. The second sealing part can be controlled to abut against the water supply pipe by adjusting the length of the connector.
