If there is a small misalignment during installation, the position of the stud in the strip-shaped hole 32 can be adjusted accordingly. The nut is limited on the side of the strip-shaped hole 32 away from the water machine unit 4. The outer diameter of the nut is greater than the width of the strip-shaped hole 32, so that the limiting effect can be achieved.
