This mechanism, comprises a driven gear 17, for example a gear wheel, whose shape is shown in figures 4 and 5. On either side of driven gear 17 a cylindrical pin 25 and 2β is respectively provided, with axes 25' and 2βf parallel to the axis 12 of gear 17» Such axes 25' and 26' are in an excentric position diametrically opposite with respect to axis 12. Guide plates 2 and 2' lay in a plane at an angle 7 with respect to pole 5, to assist a correct introduction of the fingers between the branches of a plant. Angle 7 can be calculated by a skilled person in order to balance the forces of inertia of the bodies in movement thus reducing the vibrations transmitted to an operator during the use. As shown in figure 2, gear 17 is wheeled by a pinion gear 16, in turn wheeled by an electric motor 15, preferably fed by a battery, for example a 12 Volts battery, via an electric cable 24, so that the portable device is autonomous.

This exemplary embodiment allows also to achieve lightness and ergonomy. In particular, the motor, contained in the elongated portion 41 of head 1 is protrudingly arranged with respect to the axis of pole 5, with the respective pinion gear, not shown in the figure, oriented towards pole 5, In carter 3 a cam mechanism is present similar to that shown in figure 2; therefore a driven gear 17 is present with axis 12 parallel to axis 11 of pinion gear 16. The angle 44 between axis 11 of the motor and axis 42 of pole 5 and the angle 45 between the plane 43 of the comb member and the axis 42 of the pole are optimized for balancing the forces of inertia and then the weighs. At the end opposite to motor head 1, pole 5 has a handgrip 6 to assist the grip of an operator. More in detail, the angle 45 between guide plates 2 and pole 5 is set, for example, between 5° and 90°, in particular, between 10° and 60°, preferably between 15° and 45°. In a possible embodiment, angle 44 is chosen in order to be complementary to angle 45, the angle set between the axes 11 and 43 being preferably a right angle. An articulated joint 55 for orienting head 1 with respect to pole 5, in an adjustable way and adapting to the configuration of the harvesting device, according to the spaces between the branches and/or the height of the trees. The articulated means may have one or more pivoting axes, allowing pivoting angles 51 and 52 set between -30° and +30°, preferably between -15° and +15° .
Notwithstanding, in figure 13 the pole 5 has been shown with a hinged joint 55, it is obvious that advantageously, it can be made without any joints. in figure 14 a further exemplary embodiment is shown of a portable device according to the invention, where the motor 53 is mounted along the axis of pole 5, near handgrip 6. In this case a transmission shaft is provided, not shown, between motor 53 and head 1, preferably arranged within pole 5, which in this case is tubular. The transmission shaft can have, at its end, respective resilient joints for compensating possible shifting between the axes and for reducing the vibrations transmitted to an operator. In figure 15 a detail of this handgrip 6 is shown, having a block 46 with a switch 47 and a supply cable 48. The end of pole 5 having handgrip β can provide means for extending the pole same, for example by an extension element 50 that can be inserted in an axial hole 49 of pole 5, creating for example a telescopical extension arrangement -
The foregoing description of a specific embodiment will so fully reveal the invention according to the conceptual point of view, so that others, by applying current knowledge, will be able to modify and/or adapt for various applications such an embodiment without further research and without parting from the invention, and it is therefore to be understood that such adaptations and modifications will have to be considered as equivalent to the specific embodiment. The means and the materials to realise the different functions described herein could have a different nature without, for this reason, departing from the field of the invention. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
