Le siège supérieur (31) comporte une partie de raccordement (311), deux parties de guidage (313) et deux parties de positionnement (315). La partie de raccordement (311) dépasse du siège supérieur (31) et est disposée entre le siège supérieur (31) et le siège inférieur (33), de telle sorte qu'un espace (S) est formé entre le siège supérieur (31) et le siège inférieur (33), la partie de raccordement est reliée à un dispositif d'entraînement, et les parties de guidage (313) et les parties de positionnement (315) se situent respectivement sur deux côtés opposés du siège supérieur (31). Les deux fils de coupe (50) ont chacun un corps de fil (51) et un élément de mise en prise (53) relié fixement à une extrémité du corps de fil (51). L'élément de mise en prise (53) est plus épais que le corps de fil (51). Une partie de chaque corps de fil (51) se situe dans l'espace (S). L'autre partie de chaque corps de fil (51) passe à travers la partie de guide correspondante (313). Les éléments de mise en prise (53) sont respectivement positionnés au niveau des parties de positionnement (315).
