The present embodiment also provides a faucet assembly comprising a faucet and any of the counter mounting structures of the present embodiment, the faucet being adapted to be fixedly secured to the base 1 of the counter mounting structure.

In this embodiment, since each locking member is not directly rotatably connected but is rotatably connected to one rotation shaft 4 relatively independent of each locking member, there is no concern about damage to the rotation shaft 4 caused by lack of the synchronously rotating screw member during locking. Therefore, compared with the prior art, the bench mounting structure adopting the technical scheme has good mechanical property, and can firmly lock the table top 8 without worrying about the damage of the rotating shaft 4.

In this embodiment, since the turning radii of the screw members are different, the screw members do not interfere with each other during the rotation of the locking members, so that the locking members can be turned around the turning shaft 4 to a greater extent to change the shape of the locking members, and can pass through the mounting hole 2 of the table top 8.

In this embodiment, by providing the abutment surface 9 on the base 3, and making the abutment portion 6 not protrude from the upper surface of the base 3 when abutting against the abutment surface 9, the upper surface of the base 3 can be always flush for subsequent installation of other objects.
