Furthermore, after the locating sleeve (30) connected to the main body (10), the annular edge (31) is configured to bear against and limit a position of the control valve (20). The driving block (40) has a coupling hole (41) axially penetrating through a central portion thereof. The driving block (40) is configured to be downwardly positioned into the locating sleeve (30), and the coupling hole (41) is adapted to cover around the outer periphery of the valve tube (221). In addition, a first connecting hole (42) and a second connecting hole (43) respectively penetrate through a lateral wall of the driving block (40), and a screw (80) is configured to screw in the first connecting hole (43) to bear against the valve tube (221). Moreover, an end of the handle (50) is adapted to pass through the elongated opening (33) of the locating sleeve (30) to connect to the second connecting hole (43) of the driving block (40). Through pulling the handle (50) which is coupled with the elongated opening (33), the driving block (40) driven by the handle (50) is configured to drive the valve tube (221) to have limited rotation. The adapter (60) secured on a top portion of the locating sleeve (30) is adapted to connect to the spout (70).

[0022] In one embodiment, the first connecting section (13) and the second connecting section (32) respectively have an outer threaded section and an inner threaded section thereon to engage together.

[0023] In another embodiment, each of the first extending portion (232) and the second extending portion (233) is a downward inclined surface extending from the first through hole (231).

[0024] In still another embodiment, each of the first extending portion (232) and the second extending portion (233) is formed in a fan shape, and the first extending portion (232) is larger than the second extending portion (233).

[0025] In a further embodiment, the mixing hole (243) is a recess on a top surface of the fixed valve piece (24).

[0026] In still a further embodiment, a coupling portion (61) protrudes from a bottom portion of the adapter (60), and the diameter of the coupling portion (61) is smaller than the adapter (60), and a lateral side of the coupling portion (61) comprises a cutting edge (62); a third connecting hole (34) horizontally penetrates through the upper portion of the locating sleeve (30), and the coupling portion (61) is configured to be positioned into the locating sleeve (30), and the screw (80) is adapted to screw into the third connecting hole (34) to bear against the cutting edge (62), thereby securing the adapter (60) on the top portion of the locating sleeve (30).

[0027] In a preferred embodiment, a first threaded section (71) is formed at one end of the spout (70) while a faucet head (72) is installed on the other end thereof; the spout (70) is connected to the adapter (60) through the first threaded section (71), which enables the spout (70) to be rotated about the adapter (60).

[0028] In an advantageous embodiment, the faucet head (72) is a faucet aerator.

[0029] In actual application, the faucet of the present invention is installed on a table or a kitchen counter around a water sink, and through pulling the handle (50) (as shown in FIG. 8), the valve tube (221) is configured to drive the rotating base (22) and the driving valve piece (23) to have synchronous rotations. Through aligning the second extending portion (233) with the second through hole (241) (as shown in FIG. 9), cold water is adapted to flow from one of the water inlet hole (12) through the fourth through hole (251) and the second through hole (241) into the control valve (20), and then flows through the second extending portion (233), the first through hole (231), the valve tube (221) and out of the faucet from the spout (70). When warm water or hot water is needed, a user can continue to pull the handle (50) further away from an initial position, and the first extending portion (232) is configured to gradually overlap with the third through hole (242). When the first extending portion (232) and the second extending portion (233) are communicated with the third through hole (242), the second through hole (241) and mixing hole (243) simultaneously (as shown in FIG. 10), cold and hot water are configured to be mixed to form warm water flowing out of the faucet. When the handle (50) travels farthest to reach the other end of the initial position, the second extending portion (233) is adapted to totally misalign with the second through hole (241) and the first extending portion (232) is configured to entirely cover the third through hole (242) (as shown in FIG. 11), thereby enabling the faucet to discharge only hot water. Also, the user can pull the handle (50) back to its initial position to turn off the faucet.

[0030] Comparing with conventional faucet, the present invention is advantageous because: the handle (50) is positioned at a front side of the faucet, which is convenient for a user to operate the faucet and saves water during the process of operating the faucet.

[0031] Having described the invention by the description and illustrations above, it should be understood that these are exemplary of the invention and are not to be considered as limiting. Accordingly, the invention is not to be considered as limited by the foregoing description, but includes any equivalents.
