Abstract

L'invention concerne une agrafeuse qui comprend un magasin (22) monté pivotant dans une certaine limite, sur le support d'appui (12) du socle (14) et un capot (34) pouvant pivoter d'environ 180° par rapport au magasin et au socle, entre une position fermée et une position de chargement ouverte, et portant un élément d'enfoncement (32) qui s'engage dans le magasin (22). Selon l'invention, le socle (14) est délimité à l'arrière du support d'appui (12) par une paroi de délimitation (42) arrière. L'axe de pivotement du magasin (22) et du capot (34) passe sensiblement dans le plan délimité par la surface extérieure de la paroi de délimitation (42) arrière. De plus, l'extrémité arrière (48) du capot (34) comporte une protection de support (44) partiellement cylindrique qui entoure l'axe de pivotement par endroits, comme une charnière, et qui est coaxiale audit axe de pivotement (16). Cette protection de support (44) s'engage dans un passage étroit en forme de fente (46) située entre la paroi de délimitation (42) et le capot (34), la largeur de la fente demeurant constante, lorsque le capot (34) bascule. En un point de la protection de support (44) partiellement cylindrique, il peut y avoir un cliquet d'arrêt (50) qui peut s'encliqueter dans un cran d'arrêt (52) placé à l'intérieur du support d'appui lorsque le capot (34) est ouvert.
