An anti-freeze faucet includes a housing engaged into a receptacle and having a compartment for receiving a water, a check valve device engaged into the housing for limiting the water to flow only from the receptacle to the housing, a cap mounted on the housing and having an opening communicating with the check valve device, a casing attached to the cap and having a space communicating with the opening of the cap for receiving the water from the opening of the cap and the check valve device, and including at least one outlet orifice formed therein and communicating with the space of the casing for allowing the water to flow out of the casing and to flow into the chamber of the receptacle, and including a non-circular chamber formed in the casing and communicating with the space of the casing, a non-circular follower slidably received and engaged in the non-circular chamber of the casing for guiding and limiting the follower to move up and down along the non-circular chamber of the casing only and for preventing the follower from being rotated relative to the casing, and including an inner thread formed in the follower, a plug attached to the follower for selectively engaging with the cap and for selectively blocking and opening the opening of the cap, and a shank rotatably engaged in the casing, and including a threaded segment for engaging with the inner thread of the follower and for actuating the follower to move along the non-circular chamber of the casing when the shank is rotated relative to the casing and the follower, and for moving the plug to selectively contact and engage with the cap and to selectively block and open the opening of the cap.
