The two gripper parts (5, 6) of a gripper are mounted so as to be pivotable on a shaft (12) which, in turn, is mounted rotatably in a holder (13). Connected to this shaft (12) so as to be fixed against rotation is closing lever which bears at its end a follower roller which interacts with fixed closing links. Furthermore, a resting part (16) for a compression spring (18) is connected to the shaft (12) via a spreader ring (17) so as to be fixed against rotation. This compression spring (18) is supported at its other end on a bearing part (5) which is integral with the one gripper part (5). A pivot movement of the closing lever results in a corresponding clockwise pivoting of the resting part (16), as a result of which pivoting of the one gripper part (5) into the clamping position is brought about via the compression spring (18). This one gripper part (5) is blocked in its clamping position in which the compression spring (18) is compressed and exerts a corresponding clamping force.
Les deux doigts (5, 6) d'une pince sont montés de façon à pouvoir pivoter sur un axe tournant (12) qui est monté à son tour dans un support (13). Un levier de fermeture est raccordé à l'axe (12) de façon à ne pas pouvoir tourner; ce levier porte à son extrémité un galet suiveur qui coopère avec des biellettes de fermeture fixes. Par ailleurs, une coupelle (16) de ressort de compression (18) est montée sur l'axe (12) au moyen d'un anneau à expansion (17) de façon à être solidaire dudit axe. Le ressort de compression (18) prend appuipar par son autre extrémité sur une portée (5) qui fait partie intégrante du doigt (5). Le pivotement du levier de fermeture entraîne la rotation en sens horaire de la portée (16), ce qui a pour effet, par l'intermédiaire du ressort de compression (18), de faire pivoter le doigt (5) vers sa position de fermeture. Ce doigt (5) est bloqué en position de fermeture où le ressort de compression (18) est comprimé et exerce une force de pinçage correspondante.
