  • Vice-grip pliers
    Patent number: 6227080
    Abstract: Locking grips (1) designed so that their latch lock mechanism (8) cannot travel beyond a point of alignment of its three points but locks, slightly set back with respect to this alignment, by the snap-fastening of a relief (30) of a catch (28) borne by a lever (10) behind a tooth (19) of a front end of a link (13). The catch (28) forms a trigger (28A) which allows the locking grips to be opened in a controlled way after the lever (10) has been released.
