BACKGROUND

Currently, mounting and detaching of faucets of water outlet devices are inconvenient since tools, such as wrenches, screwdrivers, etc., are generally required to mount or detach faucet main bodies, gaskets, and nuts. Especially for a three-hole faucet of a basin, mounting or detaching the three-hole faucet is time-consuming and laborious, which has strict requirements on operators and is not beneficial for improving working efficiency.

Chinese patent No. CN212772632U discloses a split type faucet for a basin, including a main body, a threaded tube, a corrugated tube, a second soft tube, and a second gasket. The threaded tube is disposed at one side of a top end of the main body, the corrugated tube is disposed at one end of an interior of the main body, one end of the corrugated tube extends out of the main body, a first gasket is sleeve on a first surface of the corrugated tube, and a first locking screw nut is sleeved on a second surface of the corrugated tube at one side of the first gasket. First round head screws are fixed to both sides of a bottom end of the first locking screw, a first soft tube is connected to one side of a bottom end of the corrugated tube, the second soft tube is disposed adjacent to the first soft tube and is connected to the bottom end of the corrugated tube, and a switch valve body is disposed at a top end of the second soft tube. However, there are technical defects as follows. The main body of the split type faucet and the switch value main body are both fixed to the basin through the gaskets and locking screw nuts, and round head screws are provided to lock the locking screw nuts; when mounting the split type faucet on the basin, tools, such as a wrench and a screwdriver are additionally required for operation in a narrow space below the basin, which wastes time and labor and further has low mounting efficiency.
