[0009] As a further improvement of the above technical solution, a first screw hole is arranged on the support arm, a third screw hole corresponding to the first screw hole is arranged on the lateral extension portion, and the first screw hole and the third screw hole are connected together by screws.

[0010] As a further improvement of the above technical solution, a water supply branch is provided on the three-way connector, and the water supply branch is connected to the support arm; a cylindrical portion is provided on the outer periphery of the water supply branch, and an annular groove is formed between the cylindrical portion and the water supply branch, and the end of the support arm is inserted into the annular groove, and the outer wall of the end of the support arm is in close contact with the inner wall of the cylindrical portion.

[0011] As a further improvement of the above technical solution, a second screw hole corresponding to the first screw hole is provided on the cylindrical portion, and the first screw hole, the second screw hole and the third screw hole are connected together by screws.

[0012] As a further improvement of the above technical solution, a through hole is provided on the vertical mounting plate, and the cylindrical portion cooperates with the support arm after passing through the through hole.

[0013] As a further improvement of the above technical solution, the support arm and the cylindrical portion are interference fit.
