Improvements in sewing machines with grapillas, consisting essentially of structuring such devices based on a hollow plate body, in which a handle and a head are defined, forming a compact unit of easy handling, articulating to the upper part of said head an external maneuvering lever, of "U" section, whose lever cooperates with another internal one that rests on a transverse pin provided in the main body and which is provided, on the one hand, with an opening for the conjunction with a flat spring, mounted longitudinally inside the body that acts as a grip, while, on the other hand, it has extreme nails.
