Abstract

L'invention a pour objet une pince d'avance munie d'un manchon de serrage fendu longitudinalement pour former mors de serrage destiné à venir saisir une barre, et d'une douille servant de logement au manchon de serrage qui se visse à l'intérieur. Selon l'invention, le manchon de serrage est muni d'un filetage extérieur en dents de scie, tandis que la douille servant de logement au manchon comporte un filetage intérieur correspondant en dents de scie, et le manchon de serrage comporte, sur son bord externe, une butée qui vient en appui contre une butée de la douille lorsque le manchon de serrage est vissé dans cette dernière.The subject of the invention is an advance clamp provided with a clamping sleeve split longitudinally to form a clamping jaw intended to grip a bar, and a sleeve serving as a housing for the clamping sleeve which is screwed to the interior. According to the invention, the adapter sleeve is provided with an external sawtooth thread, while the sleeve serving as a housing for the sleeve has a corresponding internal sawtooth thread, and the adapter sleeve has, on its edge external, a stop which comes to bear against a stop of the sleeve when the tightening sleeve is screwed into the latter.
