ABSTRACT:
The rotating pliers has an arm (1) provided at the extremity with a screw having a long pitch (2), a sleeve (3) which rotates on the screw (2). The pliers rotate when the sleeve (3) is grasped after the pliers have been closed by means of jaws (4) and (5). The pliers rotate on the fastening thread (6) of the armature (7) after the motion of lever (11). This lever is provided at the opposite extremity with pin (12). The latter slides in the shaped groove (13). In this manner, the fastening thread (6) is grasped and is caused to rotate by traction applied to sleeve (3) and it is not necessary to cause the rotation of the pliers by hand and substantial reduction of the physical work by the operator is achieved.
