<p>Subject of the invention are jerky pruning shears whose construction makes it possible that the twig (branch) is perfectly cut and that they withdraw it from the incision. The shears can be arbitrary sharpened. The jerky pruning shears consist of a handle (1) which features a welded even metal piece (2) with lower blade (3) on one end, while on the other there is an angular piece (4) which holds the handle of the incision (8). The latter is connected to the swivelling needle (7) with an even metal piece (7') having an upper blade (5) attached to it. An elastic spring (10) is attached by a screw to the upper blade (5), while the other part is attached to the even metal piece (7') and ensures the return of the blades (3, 5) into their original position so that the shears are made ready for repeated cutting.</p> |
