Further, the bottom of the supporting rod is provided with a backing plate.
Further, the link is L-shaped.
Furthermore, a first pin shaft is welded at the lower part of the operating end, a connecting hole is formed in the top of the supporting rod, and the first pin shaft is movably inserted into the connecting hole.
Furthermore, a second pin shaft is welded at the front part of the connecting end, a sleeve is welded at one side of the movable plate, and the second pin shaft is movably inserted into the sleeve.
Furthermore, an anti-skid sleeve is arranged on the operation end.
Further, the anti-skidding sleeve is a rubber sleeve.
Furthermore, a clamping groove is formed in the top of the supporting rod, and the operating end is located in the clamping groove.
Use the technical scheme of the utility model, break the operation end off with the fingers and thumb downwards, drive the fly leaf rebound, because swing joint between fly leaf and the link, the fly leaf can incline certain angle, makes the reinforcing bar be tightly the interlock in the through-hole, and the reinforcing bar rebound under the drive of fly leaf until being extracted. The utility model discloses utilize lever principle, convenient operation, laborsaving has effectively solved among the prior art inconvenient problem of reinforcing bar extraction.
