摘要： The invention relates to a pair of shears for shearing sheet metal. Known shears, for example power shears, require relatively great forces, which cannot be produced except by special gear means. For rendering it possible to manually shear even relatively thick sheets, according to the invention it is proposed that the movable blade (22) of the shears is connected to a drive mechanism (13,15,17) and is located above the stationary blade (6) of the shears in its starting position for shearing, and that the drive mechanism is supported in the stand (1) of the shears for vertical movement, whereby the dead load of the drive mechanism and of the movable blade is utilized by gravity action for the shearing work.
