Definitions

  • the invention relates to a cutting device with 00005 two 00006 jaws, of which at least one forms a cutting edge, and one which is arranged in front of the cutting edge and into which 00008 the cutting edge extends between the jaws protrude00009 the protective nose.

  • the 00024 protective lug can dip into the jaw when it is applied in 00025 in the direction transverse to the direction of extension of the jaw or 00026 of the cutting edge. As a result, the 00027 protective nose emerges from the cutting mouth. This Auswei00028 Chen can be done especially when cutting with the 00029 cutting edge. The protective nose is then acted upon by the 00030 material to be cut and deviates from the extension to the sheath.

Abstract

L'invention concerne un dispositif de coupe comprenant deux mâchoires (1, 2) déplaçables de manière à s'appliquer l'une sur l'autre au moyen d'une commande manuelle, et dont au moins l'une forme une lame (3), un nez de protection (4) émergeant dans la bouche de coupe s'étendant entre les mâchoires (1, 2), disposé devant ladite lame (3). L'invention est caractérisée en ce que le nez de protection (4) peut s'esquiver à l'encontre d'une force de rappel (7), et en ce que l'une (1) des mâchoires forme une chambre d'évitement (5), à la base (6) de laquelle prend appui l'extrémité d'un ressort (7) s'engageant par son extrémité sur le nez de protection (4).
