A portable device (2) for harvesting small fruits from a plant, by causing a vibration or a shaking movement, comprises an elongated support that is configured to be grasped (20) and has an enlarged end portion (21 )； two comb-like elements (30', 30") hinged in a first point of the enlarged end portion, each having an array (35) of fingers (36) that extends from an elongated base member (31 ',31 ") opposite to the support； an actuation unit (50) mounted to the support； a transmission mechanism (40) between the actuation unit and the comb-like elements having a transmission stem (41 ) slidably arranged along the support and connected at an own end portion (42) to the actuation unit, with two links (48) each hinged (33) in a different point of a comb-like element, and with a pin (45), at the opposite end portion (43), which is located on the transmission axis (44). The transmission mechanism is arranged to cause the stem (41 ) to reciprocate along the support, so that its end portion (43) bearing the pin (45), by reciprocating, causes the comb-like elements to rotate about the first point. The position of the pin makes it possible to arrange the two comb-like elements closer than in the prior art, which reduces the overall size of the device and allows it to be more easily moved among the branches. In a preferred exemplary embodiment, the innermost fingers (36', 36"), i.e. those closest to the longitudinal axis (24), are mounted skew to the respective comb-like elements 30', 30", for example they are arranged at predetermined respective angles (β',β") with respect to a line perpendicular to the main direction of the bases (31 ',31 "), so that they are maintained at a distance longer than a predetermined minimum distance, when the device is about the closed configuration, which prevents them from forming a sort of scissors that can cut or in any case damage the plant.Selon l'invention, un dispositif portable (2) permettant de cueillir des petits fruits d'une plante, en
