摘要： For use with a conventional trailer hitch wherein a forwardly extending tongue on a trailer is pivotally connected on a vertical main hitch axis to a support on the rear of a towing vehicle. A pair of safety links or arms extend fore and aft from each side of the tongue to the support where they are pivoted on each side of the hitch axis. The arms are longitudinally telescopic to extend and retract as the trailer moves about the hitch axis and the arm ends are connected on rigid vertical axes to the tongue and support to provide an effective traveling hitch connection should the main hitch connection be severed.
