[0019] An empty groove 20 is provided at one end of the first flange 1, and the outer wall of the first flange 1 corresponding to the empty groove 20 is fixedly connected to a limiting block 21. Due to the empty groove 20, the empty groove 20 can provide sufficient space when the first flange 1 is connected to the water pipe, so that the sleeve 22 squeezes one side of the first flange 1 to connect the water pipe, thereby ensuring the stability after the connection. The outer wall of the first flange 1 is sleeved with a sleeve 22, and the inner wall of the sleeve 22 is provided with a limiting groove 23. The position of the limiting groove 23 corresponds to the position of the limiting block 21. The sleeve 22 is connected by a bolt 18 and a nut 19.
