Abstract

Pneumatic clamp, characterized essentially by the fact of comprising a rod on which is mounted a piston located inside a cylinder provided with air intake under pressure at one of its ends, and provided with its corresponding air outlets, in the opposite end; because said rod is longitudinally orificeed to receive in the axial direction the element to be held, such as a cannula of elastic material; because said rod presents in its end third corresponding to the outlet of the cannula, lateral grooves and in longitudinal direction; because the aforementioned third end of the rod presents in its inner zone to the cylinder, a frustoconical conformation weakening in its two extreme cylindrical zones of different diameter, because the aforementioned truncated cone shape corresponds, e, an angulation of the cylinder end face, so that their internal faces are facing the lateral surface of the frustoconical shape of the stem; because the displacement of the piston from which the rod is integral is produced, the lateral wall of its frustoconical portion impinges on the internal faces of the above-mentioned angulation, which produces the narrowing of the. Section of the end of the shaft of the stem and the consequent clamping and clamping of the cannula; and because the recovery of the piston to its primitive position is produced by the action of a spring that operates at the same moment that the pressure of the air ceases.
