Abstract

La présente invention concerne une agrafeuse utilisée pour lier des feuilles de papier, etc., présentant une structure capable de prendre précisément une agrafe avec une faible force. La poussée vers le bas d’une poignée contraint un élément déclencheur (10) à déplacer un élément extracteur (20) vers l’arrière et le mouvement de l’élément extracteur contraint un point d’articulation (B) à se déplacer vers l’arrière, forçant un angle formé par un point d’articulation (A), le point d’articulation (B) et un point d’articulation (C) d’un mécanisme de frappe alternative à approcher les 180 °. Cela contraint une extrémité d’un ressort de goupille (30) à se déplacer vers le haut pour contraindre la force à s’accumuler dans ledit ressort de goupille. Quand la poignée est plus poussée vers le bas pour libérer la mise en prise entre une extrémité de tête A (12) de l’élément déclencheur et une butée (22) de l’élément extracteur, la force qui déplace le point d’articulation B disparaît. Cela force le point d’articulation B à avancer, contraignant le point d’articulation A à s’abaisser. En résultat, une lame (35) fixée à une extrémité du ressort de goupille est abaissée pour prendre une agrafe.
