Abstract
The invention relates to shears comprising a stationary blade (1) and a movable blade (2) which moves during the shearing movement of the shears. An operating mechanism (5) is arranged to affect a point of the pin (6) located at a distance from the movable blade (2). When the shears are being closed, a force is thus generated which also tries to pull the movable blade (2) towards and against the stationary blade (1) and to keep the blades (1, 2) in contact with each other. The operating mechanism (5) is arranged to affect the joint pin (6) through a sleeve-like part (7). The interior of the sleeve comprises two conical sections (8, 9), the narrowest point of the interior of the sleeve determining the point from which the sleeve-like part (7) affects the joint pin (6).
