Abstract

L'invention concerne un sécateur à deux mains du type de ceux qui possèdent des branches de coupe articulées sur un axe central, les branches de coupe possédant une tête de coupe et contre-lame respectives, chacune desquelles se prolongeant par les queues d'actionnement reliées à de longs bras susceptibles d'être actionnés par les mains de l'utilisateur lors de coupes d'effort élevé, la tête de coupe et la contre-lame présentant des queues d'actionnement qui s'insèrent dans des supports d'adaptation présentant une configuration extérieure correspondant à la section du bras à utiliser, qui comprennent des parties saillantes opposées sur leurs faces internes avec des logements respectifs présentant une forme qui admet l'intégration de butées élastiques logées à l'intérieur; les supports d'adaptation possèdent au niveau de chacune de leurs faces latérales une cannelure susceptible de recevoir les orifices emboutis formés dans le bras, de manière complémentaire sur leur face latérale opposée, ils comprennent des trous hexagonaux susceptibles de recevoir les vis de fixation, ainsi que deux orifices passants concentriques aux trous hexagonaux, entre lesdites faces latérales pour le logement des vis de fixation.
