Abstract
An adaptation device, in particular for a tractor, for coupling working tools, consisting of at least one upper link bar and lower link bars arranged below the top link bar and connected with a driving force drive through lifting rods, the upper and lower articulated bars being maintained in a supported manner by means of supports at a certain distance from each other, but being able to move relatively elastically in both directions along them, and being associated with the articulated bars coupling hooks, in particular lockable coupling hooks, characterized in that each lower link bar has associated with it a leaf spring (1, 2, 11), one end of which is rotatably or movably connected in space with the Retaining hook cavity (37) of the corresponding lower link bar (36) and whose upper end is non-rotatably coupled to the upper link bar or bars (30) or to a crossbar (7) that retains this or these and that joins the two leaf springs (1, 2, 11), the leaf springs being previously curved (1, 2, 11) in the desired bending direction or the introduction of force taking place through the crossbar in the bending direction.
