A hole (302), the other end of which penetrates the elastic body (3), the inner end of the second piston body (601) and the push plate (604) slidably arranged in the second counterbore (302) through a compression spring (603) ) connection, the second piston body (601) is provided with an L-shaped second air release channel (602), the inner end of the second air release channel (602) penetrates the push plate (604) and the closed flushing chamber (5) Internal communication, the outer end extends to the side wall of the second piston body (601), and is covered by the inner wall of the through hole (301) when the compression spring (603) is in the initial position, when the push plate (604) is subjected to closed flushing When the pushing force of the cleaning liquid in the cavity (5) is greater than the elastic force of the compression spring (603), the outer end of the second piston body (601) is gradually pressed out until the outer end of the second air release hole (602) is connected to the elastic body (3) Outside, the pressure of the cleaning fluid in the closed flushing chamber (5) is reduced.
