Abstract

New fixing pin for the assembly of parts that is characterized by consisting of a screw, which in its first section, below its tightening head offers a threaded position, followed by a smooth portion that ends in a conical tip, and which it is located inside a hollow cylindrical body, whose interior offers a first threaded section continued in another smooth sector and ending in a concave bottom, opening in opposite points two facing windows, these openings corresponding to the smooth portion, being in the inside the cylindrical body, by introducing through both windows, two claws, which in their concurrent faces offer a bevelled profile in its upper part that facilitates the penetration between both the conical end of the screw, and below each open holes in a perpendicular direction, so that they can penetrate the divergent ends of the two branches of a metal strip that lodges in the bottom of the body cylindrical po, without getting to touch the bottom of it, offering the claws on its opposite side to the insertion of the strap arms a comic, so that when projecting out of the windows, when the screw is threaded and its conical end separates the arms of the strap and consequently the lateral displacement of the claws, begin to protrude before the upper parts, which produce its affixed on the wood, action that increases as the cylindrical body is attracted upwards, to produce the strong anchorage of the spike and with it the strong unión of the pieces to assemble, having to point out that the cylindrical body offers in diametrically opposed points of its exterior, stylized fins for its anchorage on the wood in order that the rotation of the screw do not drag on the cylindrical body.
