CA 2598209

A rotatable connector pin assembly is disposed within an opening in an adapter nose, with opposite ends of the pin portion of the assembly extending outwardly beyond opposite sides of the adapter nose in axially fixed orientations relative thereto, and is used to captively and releasably retain a replaceable excavating tooth point on the nose. The configuration of the opposite pin ends permits the overall pin assembly to remain in the adapter nose during removal of the point and replacement thereof, with the pin being rotatable between a first orientation in which its ends permit removal of a point from the nose, or installation of a point on the nose, and a second orientation in which the opposite pin ends block removal of the point from the adapter nose.

Une fiche de connexion orientable est disposée dans l'ouverture d'un bec d'adaptation, ses extrémités s'étendant extérieurement par-delà chacun des côtés du bec d'adaptation et étant orientées dans le sens de l'axe de ce dernier, en position fixe. Ladite fiche de connexion a pour objet de retenir une pointe de dent remplaçable pour l'installer sur le bec d'adaptation ou l'en retirer. La configuration des extrémités de la fiche permet à celle-ci de demeurer dans le bec d'adaptation durant le retrait et le remplacement de la pointe, la fiche étant orientée dans une première position de façon que ses extrémités retirent la pointe du bec d'adaptation ou l'installent sur celui-ci, puis dans une deuxième position depuis laquelle les extrémités de la fiche bloquent le retrait de la pointe du bec d'adaptation.
