ABSTRACT:
A telescopic extensible rod, suited to be used as extension in agricultural pneumatic tools for picking fruit from trees or of cutting off branches of trees, is formed by two coaxial tubular elements, i.e. a first tubular element and a second tubular element that slides inside the first tubular element. A pneumatic actuator can be connected to the free end of the second tubular element. A coupling is mounted between the tubular elements to removably lock their reciprocal sliding. Two coaxial pipes, a first pipe and a second pipe, are located inside the tubular elements, the second pipe being designed to slide inside the first one while keeping the seal because of the presence of a sleeve mounted between the pipes and inside the first pipe. The free ends of the pipes are in fluid-dynamic connection respectively with a compressed fluid delivery and with the pneumatic actuator.
