<p>A pipe bending plier, including a planar plate connected with a housing and a pair of spaced stationary anvil members coupled with the plate, a movable presser slidably coupled with the planar plate and movable relative to the housing and the anvil members, a movable handle for moving the movable presser towards the anvil members, a fixed handle coupled with the housing and a spring coupled with the housing for holding the movable handle away from the fixed handle, a pawl-ratchet mechanism housed within the housing and comprising an extension arm on a portion thereof carrying a ratchet, and a pawl connected with the movable handle means, the ratchet being coupled with the movable presser and operatively associated with the pawl in one direction of movement of the extension arm for movement by the extension arm in one orientation thereof towards the pair of spaced stationary anvil members and in another orientation of the extension arm, the pawl and the ratchet are disengaged so that the extension arm is movable together with the movable presser towards and away from the pair of spaced stationary anvil members to bend a pipe without kinking it and to provide smooth continuous bends for different angular shapes.</p> |
