Abstract

L'invention concerne une pince comprenant une première et une deuxième partie de pince (1,2), pourvues respectivement d'une zone de préhension (G1, G2) et d'une zone de tête (K1, K2), les parties de pince (1, 2) étant reliées par une articulation (3) entre ces zones et pouvant pivoter l'une par rapport à l'autre autour d'un axe d'articulation (A). Chaque zone de tête (K1, K2) présente un élément fonctionnel (W1, W2) coudé, le premier élément fonctionnel (W1) de la première partie de pince (1) pouvant être positionné dans une position opposée au deuxième élément fonctionnel (W2) de la deuxième partie de pince (2) sur un côté du deuxième élément fonctionnel (W2). Au moins la zone de tête d'une des parties de pince, notamment les deux parties de pince, peuvent coulisser l'une par rapport à l'autre perpendiculairement à l'axe d'articulation, notamment dans l'articulation, et le premier élément fonctionnel (W1) peut se déplacer autour du deuxième élément fonctionnel (W2) pour passer dans une deuxième position opposée au deuxième élément fonctionnel (W2) sur l'autre côté du deuxième élément fonctionnel (W2).
