Rotating pliers for fastening the reinforcement rods of an armature in the building industry involving concrete casting

Wire twisting and cutting pliers comprising:

• a) a first arm having a jaw at a first end;
• b) a second arm having a jaw at a first end, said first and second arms being pivotally connected so that said jaws cooperate to form pliers to grip and cut a fastening wire for reinforcing rods;
• c) an elongate screw means mounted longitudinally on one of said first and second arms and having a longitudinally moveable sleeve thereabout engaged with said screw means so as to rotate said pliers when said sleeve is moved longitudinally;
• and
• d) means for adjustably fixing the position of said jaws to grip said fastening wire therebetween during rotation of said pliers, said means comprising a plate mounted on one of said arms so as to rotate thereabout and extending towards the other of said arms and having a hook-like bend at its free end adapted to engage said other of said arms to thereby fix the position of said jaws, said plate being adjustable laterally with respect to the arm on which it is mounted so as to adjustably vary the fixed grip position of said jaws;
• whereby by the lateral adjustment of said plate, varying diameter fastening wires may be fixedly gripped between the jaws of said first and second arms by rotatably moving said plate so that said bend thereof engages the other of said arms and upon completion of rotation of said pliers, continued squeezing of said arms disengages the bend of said plate from the other of said arms and causes said jaws to cut said fastening wire.
