  "textContent": "The device, installed on the base surface (9) of a support applied to the rear part of a self-propelled vehicle and provided with a towing element, for example of the type with a spherical articulation (12), allows to provide safe and stable extreme positions of the tilting angular lever (R) constituted by a rear segment (18) and a front segment (18a), which are offset by an angle comprised between 50° and 130°, i.e., the horizontal working position, with the rear segment arranged horizontally, and the disengagement position, in which the segment is raised, saving time; this is done by turning through one sector the locking shaft (21), which is pivoted in a lower region in the supporting fork (15), while the fulcrum of the lever is hinged in an upper region; this maneuver, performed manually by way of the transverse actuation lever (20), allows to couple alternately the locking shaft (21) with one or the other of two mutually offset hollow seats formed at the end of the front arm (18a) of the tilting angular lever (R), which are mutually angularly spaced by the same extent as the angular movement of the lever; the maneuver is obtained initially by unlocking the lever (20) from the interlocking in the tab (37) of the hub (33) in contrast with the action of the longitudinal spring (32) and then by turning said lever in contrast with the action of the torsion spring (25), controlling manually the movements of the tilting angular lever (R).",
