An adjustable wrench, which is characterized by consisting of a fixed claw that carries a rod threaded by the opposite end; the handle is threaded on said rod by means of its internal thread; when said handle is screwed, it pushes a second shank to the sliding part that carries a lower shank, the axis of which forms a sharp angle with the former. Said shank penetrates through the mobile claw pushing it and making it slide by means of a third shank that passes through the fixed claw, producing the approach of the faces that are to hold the nut. The handle also has two lugs housed in a groove made in the sliding piece and which allow it to be dragged backwards when the handle is unscrewed, with which the inverse movement takes place, that is, the separation of the faces that have to be removed. hold the nut. The axes of the three rods delimit an ideal triangle, the length of whose sides varies, according to the various positions of the key. (Machine-translation by Google Translate, not legally binding)
