Abstract

Un'avvitatrice elettrica a percussione (2), in particolare per il funzionamento ad accumulatori, presenta un dispositivo di percussione (7), con un percussore (17) azionabile con spostamento assiale. Una molla di azionamento (20), caricata periodicamente da un dispositivo di percussione (7) con scanalature a V, serve alla generazione delle percussioni. Per poter impiegare l'avvitatrice a percussione, per i casi di avvitamento facile, anche senza percussione, il dispositivo di percussione (7) è disinnestabile. A tale scopo serve un eccentrico (30), che fissa il percussore (17) nella posizione terminale assiale nella quale la molla di azionamento (20) è scaricata.(Figura 1).
