The present invention is a trailer hitch that fits in a standard 2" receiver, which allows for the selection of three different sized balls or a tow hook in an almost instantaneous manner and consists of two main components. The first is a hitch insert that fits in the standard 2" receiver hitch and is secured in the conventional manner with a hitch pin. The insert protrudes from the receiver in a generally "L"-shaped manner. The second component is a square hitch plate with a support extending from the bottom, which is secured in the lower portion of the hitch insert. The support is drilled at regular intervals to allow hitch plate to be adjusted in height to match the height of the trailer. A series of three various sized tow balls is located in each of three corners of the hitch plate, with a tow hook located in the fourth.

What is claimed is: 1. An adjustable trailer hitch, comprising: a hitch insertion assembly having, a first tubular shank adapted to be secured into a hitch receiver bracket of a towing vehicle, a boxed body having a proximal end portion and a distal end portion, the proximal end portion coupled to the first tubular shank, a hitch insert receiver coupled to the distal end portion of the boxed body; and, a hitch plate and shank arrangement having, a hitch plate capable of accommodating three differently sized ball hitches and a pulling hook; and, a second tubular shank extending from the hitch plate, the second tubular shank adapted to be secured through the hitch insert receiver, such that, the hitch plate and shank arrangement is capable of being vertically and rotationally adjusted; wherein said three differently sized ball hitches and said pulling hook are removably inserted and secured on said hitch plate; wherein the proximal end portion of the boxed body is welded to the first tubular shank using a 45 degree angled stiffener piece. 2. The adjustable trailer hitch of claim 1, wherein the second tubular shank has a plurality of adjustment holes drilled therethrough, which when aligned variably with a plurality of adjustment holes drilled through the hitch insert receiver, enables a plurality of vertical adjustments for the hitch plate and shank arrangement. 3. The adjustable trailer hitch of claim 2, further comprising: a locking pin adapted to be inserted through aligned adjustment holes drilled through the second tubular shank and the hitch insert receiver; and, a locking pin retainer for securing the second tubular shank to the hitch insert receiver. 4. The adjustable trailer hitch of claim 1, wherein the second tubular shank is rotated for rotational adjustments of the hitch plate and shank arrangement. 5. The adjustable trailer hitch of claim 1, wherein the hitch plate is disposed above the hitch insert receiver. 6. The adjustable trailer hitch of claim 1, wherein the hitch plate is disposed below the hitch insert receiver. 7. The adjustable trailer hitch of claim 1, wherein the ball hitches and the pulling hook are mounted at corner portions of the hitch plate; wherein each of said ball hitches are interchangeably mounted on said hitch plate at any desired corner position except at the corner position on which the pulling hook is mounted. 8. The adjustable trailer hitch of claim 1, wherein at least one ball hitch from said three differently sized ball hitches is mounted on a surface of the hitch plate opposite to a surface from which the second tubular shank is extending. 9. The adjustable trailer hitch of claim 1, wherein at least one ball hitch from said three differently sized ball hitches is mounted on a surface of the hitch plate from which the second tubular shank is extending. 10. The adjustable trailer hitch of claim 1, wherein the first tubular shank is inserted into a hitch receiver of the hitch receiver bracket, and locked therein using a locking pin inserted through aligned locking holes on the hitch receiver and the first tubular shank, and secured using a locking pin retainer. 11. The adjustable trailer hitch of claim 10, wherein the hitch receiver is a 2 inch hitch receiver. 12. The adjustable trailer hitch of claim 1, wherein the hitch insertion assembly is rotated by an angle of about 180 degrees along a horizontal plane for providing a plurality of configurations. 13. An adjustable hitch, comprising: a hitch insert having, a first tubular shank adapted to be secured into a hitch receiver bracket of a towing vehicle, a boxed body having a proximal end portion and a distal end portion, the proximal end portion of the boxed body coupled to the first tubular shank, and a hitch insert receiver coupled to the distal end portion of the boxed body, the hitch insert receiver oriented perpendicularly to the boxed body; an adjustable hitch device having, a hitch plate capable of accommodating three differently sized ball hitches and a pulling hook, and a second tubular shank extending from the hitch plate, the second tubular shank adapted to be secured through the hitch insert receiver; wherein said three differently sized ball hitches and said pulling hook are removably inserted and secured on said hitch plate; wherein the second tubular shank has a plurality of adjustment holes drilled therethrough, which when aligned variably with a plurality of adjustment holes drilled through the hitch insert receiver, enables a plurality of vertical adjustments for the adjustable hitch device; and wherein the second tubular shank is capable of being rotated for rotational adjustments of the adjustable hitch device; wherein the first tubular shank is inserted into a hitch receiver of the hitch receiver bracket, and locked therein using a locking pin inserted through aligned locking holes on the hitch receiver and the first tubular shank, and secured using a locking pin retainer. 14. The adjustable hitch of claim 13, wherein the hitch plate is disposed above the hitch insert receiver. 15. The adjustable hitch of claim 13, wherein the hitch plate is disposed below the hitch insert receiver. 16. The adjustable hitch of claim 13, wherein the hitch receiver is a 2 inch hitch receiver.
