  • Patent number: 5170559
    Abstract: A cutting blade (16) of rose-gripping shears cooperates with an anvil (30). A clamping piece (50), which has a clamping plate (52) which rests against the anvil (30) in the closed position, is movable together with the cutting blade (16). The said clamping piece can move backwards under spring action in order to hold a cut stem between the clamping plate (52) and the anvil (30). The spring urging of the clamping piece (50) is obtained by a spring arm (56) which extends in an arcuate section around the swivel pin (22) between the shear arms and comes against a mounting plate (58) which is connected, fixed for rotation, to the gripping lever of the cutting blade (16).
