ABSTRACT:
Shears having a locking mechanism which ensures self-locking closure without any light gap. A tumbler (24) on one limb of the shears pivoted by a slide button (22) has a cam surface (34) interacting in a self-locking manner with a catch groove (28) on a cam surface (32) on the other limb (14). The catch groove (28) can have a larger configuration in the direction of closure. An arched cam surface may also be provided, which is eccentrically located in relation to the pivoting axis of the tumbler. A fine locking device (50) for the slide button may be provided so the slide button can be fixed in different closed positions to prevent unintentional closure in the open position.
