I claim: 1. A cargo bracing device comprising: a base including two side plates, said side plates each including an orifice formed therein, a reel drum rotatably engaged in said orifices of said side plates of said base for rotatably attaching said reel drum to said base, at least one toothed disc

I claim: 1. A cargo bracing device comprising: a base including two side plates, said side plates each including an orifice formed therein, a reel drum rotatably engaged in said orifices of said side plates of said base for rotatably attaching said reel drum to said base, at least one toothed disc attached to said reel drum and rotated in concert with said reel drum, and including a plurality of disc teeth provided thereon, a spring-biased stop slidably attached to said base and engaged with said disc teeth of said at least one toothed disc, for limiting said at least one toothed disc 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, an operating arm including two legs rotatably attached to said reel drum, a spring-biased catch device slidably attached to said operating arm and engaged with said disc teeth of said at least one toothed disc, for allowing said at least one toothed disc 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 means for detachably anchoring said legs of said operating arm to said reel drum, and said legs of said operating arm being selectively disengageable from said reel drum and said base when required, said detachably anchoring means including at least one anchor member for detachably anchoring said legs of said operating arm to said reel drum, and said at least one anchor member being attached to said catch device for selectively engaging with said reel drum. 2. The cargo bracing device as claimed in claim 1, wherein said operating arm includes an opening formed in each of said legs for receiving said reel drum and for attaching said legs of said operating arm to said reel drum, and said opening of at least one of said legs includes an open portion, and said at least one anchor member is selectively engageable into said open portion of said opening of said legs. 3. The cargo bracing device as claimed in claim 1, wherein said reel drum includes two drum halves spaced away from each other for forming a strap receiving slot between said drum halves. 4. The cargo bracing device as claimed in claim 3, wherein said at least one toothed disc include two apertures formed therein for receiving said drum halves of said reel drum respectively and for allowing said at least one toothed disc to be rotated in concert with said reel drum. 5. The cargo bracing device as claimed in claim 1, wherein said base includes a channel formed in each of said side plates for slidably attaching said stop. 6. The cargo bracing device as claimed in claim 4, wherein said base includes a peg formed in at least one of said side plates, and a spring member includes a ring engaged with said peg of said side plate, and a first end engaged with said side plate of said base and a second end for engaging with said stop and for biasing said stop to engage with said disc teeth of said at least one toothed disc. 7. The cargo bracing device as claimed in claim 6, wherein said stop includes a perforation formed therein for receiving said second end of said spring member. 8. The cargo bracing device as claimed in claim 6, wherein said base includes a notch formed in at least one of said side plates and communicating with said channel of said side plate and located beside said peg for forming said peg and for receiving said ring of said spring member. 9. The cargo bracing device as claimed in claim 1, wherein said operating arm includes a groove formed in each of said legs for slidably attaching said catch device. 10. The cargo bracing device as claimed in claim 9, wherein said operating arm includes a projection formed in at least one of said legs, and a spring member includes a ring engaged with said projection of said leg, and a first end engaged with said leg of said operating arm and a second end for engaging with said catch device and for biasing said catch device to engage with said disc teeth of said at least one toothed disc. 11. The cargo bracing device as claimed in claim 10, wherein said catch device includes a perforation formed therein for receiving said second end of said spring member. 12. The cargo bracing device as claimed in claim 10, wherein said operating arm includes a notch formed in at least one of said legs and communicating with said groove of said leg and located beside said projection for forming said projection and for receiving said ring of said spring member. 13. A cargo bracing device comprising: a base including two side plates, said side plates each including an orifice formed therein, a reel drum rotatably engaged in said orifices of said side plates of said base for rotatably attaching said reel drum to said base, at least one toothed disc attached to said reel drum and rotated in concert with said reel drum, and including a plurality of disc teeth provided thereon, a spring-biased stop slidably attached to said base and engaged with said disc teeth of said at least one toothed disc, for limiting said at least one toothed disc 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, an operating arm including two legs rotatably attached to said reel drum, a spring-biased catch device slidably attached to said operating arm and engaged with said disc teeth of said at least one toothed disc, for allowing said at least one toothed disc 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 means for detachably anchoring said legs of said operating arm to said reel drum, and said legs of said operating arm being selectively disengageable from said reel drum and said base when required, said detachably anchoring means including at least one anchor member for detachably anchoring said legs of said operating arm to said reel drum, and said at least one anchor member being attached to said catch device with at least one fastener.
