A single-handle faucet includes a faucet body which has an open top and which is formed with a spout, an upright water pipe provided inside the faucet body, and a cartridge stem extending slidably into the upright water pipe and being movable between a first position, in which water flow from the water pipe to the spout is permitted, and a second position, in which water flow from the water pipe to the spout is not permitted. A cover unit is mounted on the open top of the faucet body and has an apex that is formed with a curved slit. A driving piece has a pair of opposite pivot arms which extend downwardly through the curved slit and which have lower ends pivoted to the cover unit, and a curved extension which extends downwardly through the curved slit and which is in sliding contact with an inner wall surface of the cover unit. The curved extension is formed with a toothed inner surface. A driven piece is connected to a topmost end of the cartridge stem and has a rack formed thereon. A pinion is mounted rotatably within the cover unit and interengages the rack and the toothed inner surface. A lever has one end extending above the apex of the cover unit and is connected to the driving piece.
