Self-adjusting pliers for grasping a work piece include first and second plier members each including a handle portion, a jaw portion, and an intermediate portion therebetween. The self-adjusting pliers include a first pivot pin about which the first and second plier members pivot permitting the jaw portions to converge on a work piece and grasp the work piece in response to initial movement of the handle portions toward each other. The self-adjusting pliers further include a second pivot pin about which the pliers pivot once pivoting has been terminated about the first pivot pin so as to permit a further grasping force to be applied to the work piece in response to continued movement of the handle portions toward each other. The second pivot pin is closer to the jaw portions than the first pivot pin to allow for a greater mechanical advantage to be obtained. The self-adjusting pliers also include a biasing spring for biasing the handle portions away from each other and the jaw portions away from each other. Self-locking pliers are also provided, either in combination with the self-adjusting pliers or individually, for automatically locking the jaw portions into engagement with a work piece.
L'invention porte sur des pinces autoréglables servant à saisir un objet comportant deux éléments comprenant chacun une poignée, une mâchoire, et une partie intermédiaire. Lesdites pinces comprennent également un premier axe autour duquel pivotent les deux éléments pour permettre aux mâchoires de converger sur une pièce et de la saisir en réponse au mouvement des poignées l'une vers l'autre, ainsi qu'un deuxième axe autour duquel pivotent les deux éléments après achèvement du premier pivotement pour permettre un serrage supplémentaire de la pièce alors que se poursuit le mouvement des poignées l'une vers l'autre. Le deuxième axe est plus proche des mâchoires que le premier d'où un plus fort avantage mécanique. Les pinces sont également munies d'un ressort écartant l'une de l'autre les poignées et les mâchoires. Il existe par ailleurs des pinces autoblocantes, soit combinées auxdites pinces autoréglables, soit individuelles, qui bloquent automatiquement les mâchoires sur la pièce.
