A low-end truss is welded to the bottom of the left end of the steel bar set. According to the straightener protection device, through the protection ring layer formed by the steel bar sets welded to the outer portion of the middle-distance round steel and matched with limiting supporting of the large-diameter round steel and the small-diameter round steel, when the straightener protection device is used, hemp velvet ropes wound around the outer portions of the middle-distance round steel, the large-diameter round steel and the small-diameter round steel conduct damping on coiled steel bars passing through the interiors of the steel bar sets; and the hemp velvet rope is used as a medium, so that direct contact between the middle-distance round steel, the steel bar group, the large-diameter round steel and the small-diameter round steel and the coiled steel bars is avoided, and the use environment of the device is improved.
