Abstract

Il dispositivo di fissaggio comprende una base (40), un corpo di base (50), una barra di pressione (60) e una molla di torsione (70). La base (40) è dotata di un foro passante (42) ed è solidale con il corpo di base (50) che ha struttura ad U e contiene uno spazio di alloggiamento (52) dotato di un canale (54) in comunicazione con detto foro passante (42). La barra di pressione (60) è montata nello spazio di alloggiamento (52) in modo che la sua parte di arresto dentellata (64) sia posizionata di fronte a detto canale (54). La molla di torsione (70) si compone di due corpi anulari (72) con un'estremità in comune che forma una parte premente (74) e con l'altra estremità che forma una parte di supporto (76). La molla di torsione (70) è montata nello spazio di alloggiamento (52) così che i due corpi anulari (72) sono accoppiati al perno di rotazione (78), la parte premente (74) abbraccia la barra di pressione (60) e le due parti di supporto (76) sono sostenute in un punto predeterminato.(FIG. 7).
