Pneumatic pruning shear, characterized all of why is constituted with a hollow handle equipped with a fixed blade on which is articulated another corresponding moving blade, which handle determines an internal chamber in which a piston is housed that is related by means of a connecting rod with said movable blade, said piston being subjected on the one hand to the action of a recuperating spring, while on the other part thereof a conduit comes from a pneumatic intake in the said chamber, being arranged in said conduit. A shutter valve operable by an external control arm, which valve serves as a shutter in turn of an exhaust outlet to which it closes and vice versa; all of this pushes the piston against the recoil spring, the drive of the moving blade.
