[0004] According to the patent case proposed above, existing faucets all have a threaded locking tube. When installed on a basin or a countertop, the locking nut needs to be screwed into the lower end of the threaded locking tube until the locking nut is pressed against the basin or the countertop. However, due to the small space under the basin or the countertop, this operation is quite difficult. Because the faucet is set at the inner corner of the basin or the countertop, the location is remote and the line of sight is poor, and it is difficult to apply appropriate force by hand to rotate the locking nut to the lowest end. It requires certain skills and patience and is very time-consuming and laborious. Therefore, a locking mechanism for the threaded locking tube at the bottom of the faucet is proposed to solve the above-mentioned problems. Utility Model Content
