Abstract
This invention is about the fastening belt with freely rotatable drag hooks, which includes two drag hooks. The said drag hooks have an upper cover and a bottom cover, with the hook fixed in the front of the drag hooks; one elastic rope to link the two drag hooks, which is made from stretchable material. Two rotatable linker and two ends of elastic rope are fixated inside the rotatable linker. The rotatable linker is connected with the rear rotation of the drag hook. The hook and the elastic rope are linked by the rotatable linker and the drag hook is linked with the rotatable linker. Thus, the drag hook can rotate freely in the elastic rope. The rope does not kink when in use, which not only prolongs the life of elastic ropes, but also reinforce the reliability of the connection between the drag link and the elastic rope.
