Claim:
1. An anti-freeze faucet structure comprising: a first pipe including an orifice defined on a first end thereof, an outlet adjacent to the orifice, an inlet formed on a second end thereof, a stop rim arranged on an inner wall thereof proximate to the inlet, and an inner screwing section arranged therein; a second pipe being hollow and including an aperture defined on one end thereof and communicating therewith, with the second pipe also including a rotatable knob mounted on a top end thereof, wherein the second pipe is disposed in the first pipe; a first control valve joined with the second pipe by using an upper end and including a through hole formed therein and communicating with the aperture, with the first control valve also including an outer screwing section arranged around an outer wall of a lower end thereof to screw with the inner screwing section of the first pipe, wherein the second pipe is rotated to control the first control valve to move upwardly or downwardly; with the first control valve further including a water passage above the outer screwing section and a water channel formed in the lower end thereof adjacent to the outer screwing section; a spring mounted in the through hole of the first control valve and having a first end stopped by a limiting rib in the through hole; a check valve secured in the through hole of the first control valve and pushed by a second end of the spring, with the check valve including a stopping plug fixed on a first end thereof, wherein the stopping plug moves to open an opening of the check valve or to close the water channel of the first control valve, with the check valve also including a water stop portion for starting or stopping water between the aperture and the water passage; wherein when the stopping plug opens the water channel, the water stop portion stops water between the aperture and the water passage; and wherein when the stopping plug closes the water channel, the water stop portion starts the water between the aperture and the water passage; and a second control valve connected with the water channel of the first control valve by a first end to position the spring and the check valve, with the second control valve also including an inlet channel arranged on an outer wall thereof and a close ring disposed on a second end thereof.
