摘要：
It comprises in principle an end motor adjacent to a reinforced structure provided with control knobs, and extending from that reinforced structure an elongated tubular body ending in a head with a rotating rotor wherein a cutting device receiving the motion from the motor through an internal transmission is connected. It is characterized in that the cutting device (8) comprises a support (10) with at least one pair of cutting chains (15) fixed at equidistant points from the geometric center of said support (10), while said points are separated by an equidistant angular space also with respect to said geometric center of the support (10). It also includes means for preventing relative rotations of screws for fixing the chains to the support (10), as well as means for preventing relative rotations of end links for fixing the chain to the mentioned screws.
