Abstract:
A lopper comprising:a lopping head having a spring-biased blade pivotally connected to a jaw about a pivot point, the jaw cooperating with the blade to sever a workpiece received in a bight formed by the jaw; a drive mechanism connected to the lopping head; an elongate housing connected to the drive mechanism; the drive mechanism comprising: a first mating portion and a second mating portion selectively rotatable with respect to one another about an axis permitting adjustment of the position of the lopping head relative to the elongate housing; the first mating portion being connected to the elongate housing and the second mating portion being connected to the lopping head; a first wheel rotatable about the axis; a second wheel rotatable about the axis and coupled to the blade by a head line, the head line being connected to the second wheel at a first connecting point such that the head line is wound about a guiding surface of the second wheel as the second wheel rotates about the axis; and a driving line arrangement comprising a driving line arranged to rotate the second wheel and the first wheel together when the driving line is drawn and to keep the first wheel stationary while the second wheel rotates when the position of the lopping head is adjusted relative to the elongate housing.
