[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figures 1 to 7 As shown, this embodiment includes a faucet body 1, a ceramic valve core 2, a valve core drive assembly 3, a handle connector 4, and an operating handle 5. The faucet body 1 adopts an integral molding structure, which ensures the overall structural strength and sealing performance. An external threaded rod 11 is formed at the lower end of the faucet body 1. The external threaded rod 11 is used to cooperate with the mounting hole on the basin, and the entire faucet is fastened to the basin by the fixing nut 6 connected thereon. A water flow pipe 12 is provided inside the faucet body 1 for conveying cold water. An installation cavity 13 is formed above the water flow pipe 12. The ceramic valve core 2 is set inside the installation cavity 13 for controlling the flow of water. An internal through-hole outlet 14 is formed on one side of the faucet body 1 to discharge the cold water controlled by the ceramic valve core 2.

[0016] like Figures 1 to 7As shown, the handle connector 4 is fixedly installed on the upper end of the faucet body 1 by a threaded connection or other suitable method, and is used to support and connect the operating handle 5. An internal thread ring 131 is formed on the inner wall of the mounting cavity 13. Correspondingly, an external thread groove 21 is formed on the outer periphery of the ceramic valve core 2. The external thread groove 21 engages with the internal thread ring 131, so that the ceramic valve core 2 can be installed and fixed in the mounting cavity 13 by rotation, and can achieve a certain degree of lifting and lowering to adjust the sealing state. The ceramic valve core 2 has a hollow cavity structure, and a through hole 22 is opened at its upper end.
