Abstract
Il presente trovato è relativo ad un meccanismo di movimentazione del chiavistello di bloccaggio automatico e sblocco comandato delle rotule di attrezzi portati e semiportati da macchine agricole, per ganci inferiori di attacchi a tre punti, il quale si compone di un aggetto centripeto nella sede di movimento del chiavistello al quale è articolata una bielletta a cui è a sua volta articolata una estremità del chiavistello volta all'interno e che lavora in contrasto con mezzi elastici, essendo previsti organi di blocco dell'asta in configurazione aperta del chiavistello.
