<p>The attachment device for work tools is rotatingly constrainable, about two parallel axes (21, 22), at an end of a mobile arm (20). The device comprises at least two attachment elements (2, 3) engageable to respectively attachment counter-elements (18, 19) solidly constrained to a work tool, at least a first (2) of which is mobile in relation to the other (3), from a hooked-up position, at which the attachment element (2, 3) are engaged to the counter-elements (18, 19) and the work tool is constrained to the mobile arm (20), and an unhooked position, in which the attachment elements (2, 3) are not engaged to the counter-elements (18, 19) and the work tool is free of the mobile arm (20). The first attachment element (2) is mobile by means of a cam mechanism (4).</p> |
