A fast looping-up and releasing rope loop assembly includes two one-way locking devices, at least one band, and a buckle. The one-way locking device includes a body constituted by a base and a cover. The one-way locking device allows the pull rope to extend therethrough and to move with respect thereto along a single direction. By inserting the pull rope through a rope entry opening of the base of the one-way locking device and further extending the rope around a rotary disk and a rotary wheel arranged inside the locking device and extending out of the locking device, the one-way locking device that locks the movement of the rope in an opposite direction is completed. When the rope is jammed due to excessive tightening, a presser of the buckle is depressed to release the one-way locking device from the jamming condition so that efficient loop-up and release can be realized.

I claim: 1. A fast looping-up and releasing rope loop assembly comprising two one-way locking devices, a pull rope, a band, and a buckle, wherein: the two one-way locking devices lock the pull rope in such a way to each allow the pull rope to move in a single direction, the band has an end coupled
I claim: 1. A fast looping-up and releasing rope loop assembly comprising two one-way locking devices, a pull rope, a band, and a buckle, wherein: the two one-way locking devices lock the pull rope in such a way to each allow the pull rope to move in a single direction, the band has an end coupled to the buckle and an opposite end extending through a slot defined in a metal plate of the first one of the one-way locking devices and then through a slot defined in a metal plate of the second one of the one-way locking devices, the end of the band being further extending through a slot defined in the buckle in front of a presser whereby the band connects between the two one-way locking devices and the pull rope is adapted to loop up an opening of a covering sack; and wherein each of the one-way locking devices comprises a base, a cover, a rotary disk, a rotary wheel, and a locker, and wherein the base forms at one side thereof a rope entry opening and two holes on opposite sides of the rope entry opening, two bolts respectively extending in a down-to-up direction through the holes and engaging the cover to rotatably support rollers, a recess being centrally formed in the base with a central shaft mounted at a center of the recess; the cover forming at one side thereof an entry opening, the cover also forming a recess in which a positioning hole, a positioning post, and a slot; the rotary disk forming a central bore and having a top face, which forms a cavity that has a circumference forming ratcheting teeth and a bottom face that forms raised ribs and an engagement peg corresponding in shape to an engagement bore; the rotary wheel forming the engagement bore and having a top face forming raised ribs; the locker comprising a bar from which an operation arm extends, a tongue extending from the bar, the tongue being provided with a spring for resilient returning after being rotated, a block being formed on a bottom of the operation arm; and the buckle comprising a chassis of which one end is coupled to the band, the chassis being provided with a spring-biased presser. 2. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the band comprises two separate sections, of which one is coupled to the buckle and the metal plate of one of the one-way locking devices and the other is coupled to the metal plate of the other one of the one-way locking devices. 3. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the base of the one-way locking device forms at one side thereof an extension plate that forms on left and right side portions thereof two holes. 4. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the cover of the one-way locking device forms at one side thereof an extension plate that forms on left and right side portions thereof two holes. 5. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the rotary disk has a bottom that has a configuration having a protruding central portion and a reduced circumferential portion. 6. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the rotary wheel has a body that has a configuration having a protruding central portion and a reduced circumferential portion. 7. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the engagement bore of the rotary wheel of the one-way locking device is octagonal. 8. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the engagement peg that is formed in the bottom of the rotary disk and corresponds in shape to the engagement bore and the engagement bore defined in the center of the rotary wheel are integrally formed together. 9. The fast looping-up and releasing rope loop assembly according to claim 1, wherein the tongue of the locker of one-way locking device forms a through hole and wherein a spring is connected between the through hole and the positioning post of the cover.
