Abstract: This invention relates to trailer hitches generally and more specifically to a hitch that may be swiveled and extended as necessary to couple a trailer thereto and readily align and lock the hitch in transportation mode. The hitch has a base plate with a partial semicircular perimeter having a trunnion formed at its center of radius, a tubular housing secured at the trunnion atop the base plate to permit arcuate movement relative to the base plate, and tubular housing having a safety member thereunder which protrudes beneath the semicircular perimeter to limit relative vertical movement between the tubular housing and the base plate, a slide bar captured within said tubular housing with a towing ball projecting beyond said housing for limited linear movement therein, and a spring biased locking pin for releasable securing the trailer hitch with the slide bar retracted and the tubular housing centered along the perimeter.
