[0034] In detail, the end, close to the transmission shaft rod 20, of the displacement seat 18 is fixedly connected with a pressing frame, and the side, close to the pressure receiving sheet 22, of the pressing frame is fixedly connected with a noise reduction pad, the pressing frame can be used for forming effective contact with the pressure receiving sheet 22 when the displacement seat 18 continuously displaces, and the transmission shaft rod 20 can be driven to adaptively displace.

[0035] Further, the outer side of the transmission shaft rod 20 is fixedly connected with a blocking pad, the material of the blocking pad is rubber, and the blocking pad is used for tightly adhering to the connecting position of the transmission shaft rod 20 and the filter pipe 2 after the limiting plate 13 contacts the mounting cylinder 4, so that the connecting position of the transmission shaft rod 20 and the filter pipe 2 is sealed, and the medium is prevented from leaking out.
