  • Patent number: 8651399
    Abstract: A structure to hang a showerhead includes a fixed base and a supporting unit, wherein the supporting unit has two clamping arms and two conjugating arms, and one side of the clamping arms has a wedging surface that has two conjugating recessed arcs with an inclined angle corresponding to a mounting surface of the fixed base, and the inclined angle of one recessed arc is smaller than the other recessed arc. A conjugating surface extends from one end of the wedging surface, and engages with the other conjugating surface of the other clamping arm. An engaging surface is formed on the other side of the clamping arm to engage with the conjugating arms. According to this structure, the angle of the showerhead can be adjusted based on different inclined angles of the conjugating recessed arcs to further achieve the goal of easily adjusting the angle of water output from the showerhead.
