Abstract

L'invenzione ha per oggetto un portautensili in macchine utensili a mano, in particolare in trapani a mano o in apparecchi a percussione, per la trasmissione di un moto rotatorio e/o di un moto di percussione ad un utensile, laddove due nervature di trascinamento in rotazione (14) del portautensili (10) s'impegnano in due scanalature di trascinamento in rotazione (20) del gambo (23a) dell'utensile, mentre almeno un corpo di bloccaggio (19) del portautensili (10) s'impegna in una delle due rientranze di bloccaggio (21) nel gambo dell'utensile. Per un trascinamento in rotazione maggiormente sollecitabile è previsto il fatto di applicare sulla circonferenza del foro d'alloggiamento (13) una scanalatura supplementare (22) estendentesi assialmente che, nel senso di rotazione, risulta vicina ad almeno una delle nervature di trascinamento in rotazione (14), raggiunge l'estremità anteriore del foro d'alloggiamento (13), e nella quale s'impegna una nervatura supplementare (24) prevista sul gambo (23a) dell'utensile (Figura 3).
