<p>A pruner (10) comprising a first elongated member (12) and a second elongated member (14) coupled to a metal plate (16). The metal plate (16) has a central aperture (38), a forwardly extending blade (34) and a rearwardly extending tang (36) having a second aperture (40) offset from the central aperture (38). A jaw (20) is mounted on the first elongated member (12). A power lever (44) having a first end (46) and a second end (48). A first coupler (50) pivotably mounted in the central aperture (38) and coupling the first member (12) to the plate (16), with a second coupler (52) pivotably mounted in the second aperture (40) and coupling the second member (14) to the plate (16). The power lever (44) is coupled to the first and second elongated members (12,14) by a third coupler (54) pivotably coupling the first end (46) of the power lever (44) to the second member (14) and a fourth coupler (56) pivotably coupling the second end (48) of the power lever (44) to the first member (12). The power lever (44) forces the second member (14) to move linearly toward the first member (12) for pivotable movement of the blade (34) and jaw (20) in response to linear movement of the first and second members (12,14). <IMAGE></p> |
