I claim: 1. A ratchet buckle device comprising: a base including two side plates, said side plates each including an orifice formed in an operating end portion thereof, and each including a channel formed therein, and each including a protrusion extended into said channel of said side plate, and each including an operating segment and a release segment and an unlock segment formed in said operating end portion thereof, a reel drum rotatably engaged in said orifices of said side plates of said base for rotatably attaching said reel drum to said base, two toothed discs attached to said reel drum and rotated in concert with said reel drum, and each including a plurality of disc teeth provided thereon, a spring-biased stop slidably attached to said channels of said side plates of said base and including two limbs for detachably engaging with said disc teeth of said toothed discs, and for limiting said toothed discs and said reel drum to rotate relative to said base in an active direction and for preventing said reel drum from being rotated in a reverse direction relative to said base, said protrusions of said side plates being engageable with said stop for tilting said stop relative to said side plates of said base, and for allowing said limbs of said stop to be moved up and down relative to said side plates, a latch pivotally attached onto said side plates of said base with a shaft for allowing said latch to be tilted relative to said side plates, and said latch including two fingers for engaging with said disc teeth of said toothed discs and for limiting said toothed discs and said reel drum to rotate relative to said base in the active direction only and for preventing said reel drum from being rotated in the reverse direction relative to said base and for allowing said reel drum to rotate in the active direction relative to said side plates of said base, an operating arm including two legs rotatably attached to said reel drum, and including an opening formed in a mounting portion of each of said legs for receiving said reel drum and for attaching said legs of said operating arm to said reel drum, and said legs each including a primary cam member and a secondary cam member provided on said mounting portion of said leg of said operating arm for selectively engaging with said stop and said latch and for selectively disengaging said limbs of said stop from said disc teeth of said toothed discs and for selectively disengaging said fingers of said latch from said disc teeth of said toothed discs, and a spring-biased catch device slidably attached to said operating arm and engaged with said disc teeth of said toothed discs, for allowing said toothed discs and said reel drum to be rotated relative to said base by said operating arm in the active direction and for preventing said reel drum from being rotated in the reverse direction relative to said base by said operating arm, and said operating segments of said side plates each including an outer diameter smaller than that of said disc teeth of said toothed discs for allowing said disc teeth of said toothed discs to be extended radially and outwardly relative to said operating segment of said side plates of said base and for allowing said pawls of said catch device to be engaged with said disc teeth of said toothed discs, and said release segments of said side plates each including an outer diameter greater than that of said disc teeth of said toothed discs for allowing said disc teeth of said toothed discs to be shielded within said release segment of said side plates of said base and for preventing said pawls of said catch device from being engaged with said disc teeth of said toothed discs, and said unlock segments of said side plates each including an outer diameter greater than that of said disc teeth of said toothed discs for preventing said pawls of said catch device from being engaged with said disc teeth of said toothed discs, and said primary cam members of said legs of said operating arm being engageable with either of said stop or said latch for selectively disengaging said stop or said latch from said disc teeth of said toothed discs when said catch device is engaged with said release segment of said side plates of said base, and said primary cam members and said secondary cam members of said legs of said operating arm being engaged with said stop and said latch for disengaging said stop and said latch from said disc teeth of said toothed discs when said catch device is engaged with said unlock segment of said side plates of said base. 2. The ratchet buckle device as claimed in claim 1, wherein said latch includes two flaps extended downwardly therefrom and pivotally attached onto said side plates of said base with said shaft. 3. The ratchet buckle device as claimed in claim 1, wherein said base includes a base plate provided between said side plates, and a peg extended from said base plate and having a space formed in said peg for slidably receiving a tail of said stop and for allowing said stop to be tilted relative to said side plates. 4. The ratchet buckle device as claimed in claim 1, wherein said base includes an opening formed in each of said side plates and communicating with said channel of each of said side plates for allowing said stop to be tilted relative to said side plates.
