Abstract

L'invention concerne une tenaille (1) comportant deux branches (2, 3) qui se croisent. Une articulation fixe est formée au moyen d'un pivot d'articulation (8). Le pivot d'articulation (8) comporte dans tous les cas, en association avec un côté extérieur (18) d'une branche de tenaille (2, 3), une première partie conique (19) s'élargissant vers le côté extérieur (18). En outre, la branche de tenaille (2, 3) comporte une seconde partie conique associée (21) qui vient en appui sur la première partie conique (19) et qui se prolonge par une première partie d'embouchure (22) qui débouche dans le côté extérieur (18) de la branche de tenaille (2, 3). L'invention vise à améliorer davantage fonctionnellement une tenaille du type en question. À cet effet, le pivot d'articulation (8) comporte une seconde partie d'embouchure (20) qui vient se superposer à la première partie d'embouchure (22) à partir du côté extérieur (18) de la branche de tenaille (2, 3) et perpendiculairement à un axe d'articulation (x). Les première et seconde parties d'embouchure (22, 20) délimitent radialement et périphériquement entre elles un espace libre annulaire circulaire (23) dont la dimension radiale (a) correspond à entre 0,05 et 0,15 fois la dimension radiale (b) du pivot d'articulation (8), mesurée à partir de l'axe d'articulation (x), au niveau de la seconde partie d'embouchure (20).
