PERFECTED PNEUMATIC NEEDLE HOLDER, which is characterized by being formed by two tubular bodies that plug one into another telescopically and of which the lower one has at its base the housing of the needle, which is fixed by a prisoner, and two exits of air, being attached to the piston rod that penetrates the bottom in the upper body, being surrounded on either side of this bottom by coil springs and ending in its upper part in a seat to which a leather piston is fixed, which receives the air sent by the pump on its upper part, in such a way that when descending the stem drags with it the body in which the needle is lodged and, when the pneumatic pressure ceases, the spring tends to recover its rest position, elevating to the piston with movement braked by the lowermost spring, with which it acquires a movement of alternative vertical displacement that achieves the desired effect of vibration of the needle, whose handling is fac illita by the knurling and recess practiced in the upper body, for better adaptation of the hand.
