The inner part of the pipe body 13 is provided with a sliding groove, so that the outer shell 14 and the limiting column 20 can slide vertically. The inner part of the valve body 1 is provided with the same sliding groove and a cylindrical sliding groove, so that the limiting column 20 can rotate. When the limiting column 20 slides into the cylindrical sliding groove, the outer shell 14 rotates by 90 degrees, so that the outer shell 14 drives the limiting column 20 to rotate in the cylindrical sliding groove and is perpendicular to the other sliding groove, thereby achieving the auxiliary limiting deviation effect.
