Abstract

Coupling structure between head and handle for hammers, axes or related tools, essentially characterized by a drill hole through the middle of the head, whose orifice comprises two sections, axially co-aligned and interconnected, of different pitch and configuration, one of them being located in the upper part, cylindrical, and the immediate interior, conical oval, inserted in the latter, adjusted and in correspondence of form, the end of the handle that is provided with a threaded means that is arranged in reciprocity and joined to another internally threaded tubular element, both threaded means constituting a retention and/or anchoring system. Coupling structure between head and handle for hammers, axes or related tools. According to the previous claim, and because the second tubular threaded means is constituted by a cylindrical pin, provided with a blind internal thread, suitable to be linked to the first threaded means attached to the handle and provided with an upper end thickened by a discoidal flange, which supports over the elastic bushing. 3. Coupling structure between head and handle, for hammers, axes or related tools, according to the previous claims and because the space intercalated between the head of the second threaded means and the bottom of the cylindrical housing of the head is occupied by an elastic bushing, container of at least one of the threaded means. 4. Coupling structure between head and handle for hammers, axes or related tools, according to the previous claims and because the first threaded means is constituted by a pin, part of which projects out of the handle at its upper end while the remaining portion is contained within it. 5. Coupling structure between head and handle for hammers, axes or related tools. (Machine-translation by Google Translate, not legally binding)
