ABSTRACT:
A lopper includes a slender rod and a pruning means mounted on a top of the rod. The slender rod includes an inner tube and an outer tube telescoped mutually such that the inner tube is shiftable in the outer tube for changing the length it jutting out from the outer tube. An extension-control unit is provided at the border region between the inner tube and the outer tube for positioning the inner tube. A fist actuating unit and a second actuating unit are provided at the outer surface of the outer tube. The fist and second actuating units are connected with the pruning means through a first rope, a second rope and a third rope so that when a user pulls the first or second actuating unit, a shear assembly of the pruning means can be closed to cut branches and leaves of plants.
