The subject invention, a collet receiver hitch, has a receiver tube with collet features, and a collet collar to eliminate the problem movement of the draw bar/mount inside the receiver. The first part is a collet receiver tube with an open end for accepting the ball mount shank. The second part is an outside collet collar. The outside collet collar is drawn onto the collet receiver tube, thereby causing the wedging action that, in turn, centers and holds the mount shank. The hitch pin is still required, and its use does not impair the subject invention.

1. A collet receiver mechanism comprising: a square collet receiver tube, said square collet receiver tube comprises an open end with tapered flexible walls, said square collet receiver tube further comprises a collet receiver tube flange affixed to an outside,an outside collet collar member with a central aperture configured to accept a ball mount shank;a tensioning means for anchoring said outside collet collar member to said collet receiver tube flange, urging said outside collet collar member onto said collet receiver tube open end with tapered flexible walls and forcing said tapered flexible walls to flex, thereby contacting the ball mount shank. 2. The collet receiver mechanism of claim 1 wherein said collet receiver tube flange is spaced away from said open end of said square collet receiver tube and has an array of threaded apertures to allow fasteners to connect therethrough. 3. The collet receiver mechanism of claim 1 wherein said open end with tapered flexible walls has four tapered external wall surfaces. 4. The collet receiver mechanism of claim 1 wherein said open end with tapered flexible walls is formed by removal of corner portions of said square collet receiver tube so as to form flexible flat wall portions. 5. The collet receiver mechanism of claim 1 wherein said collet receiver tube flange has an array of apertures configured to allow fasteners to pass therethrough. 6. The collet receiver mechanism of claim 3, wherein said central aperture of said outside collet collar member has tapered internal surfaces. 7. The collet receiver mechanism of claim 1 wherein bolts are provided with an anchoring feature, to engage said outside collet collar member, and a threaded portion is spaced from said anchoring feature and threadably mounted to said collet receiver tube flange. 8. The collet receiver mechanism of claim 6 wherein tightening said tensioning means urges said outside collet collar member forcefully onto said collet receiver tube tapered flexible walls causing contact between said tapered internal surfaces of the outside collet collar member and said tapered external wall surfaces of said collet receiver tube tapered flexible walls, thereby flexing the walls onto the ball mount shank, thereby centering and holding said ball mount shank in position. 9. The collet receiver mechanism of claim 8 wherein by loosening said tensioning means, the outside collet collar member is allowed to back away from the collet receiver tube, thereby unclamping said ball mount shank, thus allowing its removal. 10. A collet receiver mechanism having a square tube with an open end with tapered flexible walls, and an outside collet collar that fits onto the open end of said square tube comprising: a collet receiver tube comprising said open end of said square tube, wherein said open end of said square tube has four external tapered-wall surfaces formed by removal of corner portions of said square collet receiver tube, creating said tapered flexible walls;said outside collet collar comprising a central aperture with internal tapered surfaces configured to accept a ball mount shank, said outside collet collar further comprising an array of apertures to accept fasteners;a tensioning means for anchoring said outside collet collar to a hitch pin with fasteners and hex nuts, and urging said outside collet collar onto said collet receiver tube open end, and forcing said tapered flexible walls to flex into contact with the ball mount shank. 11. The collet receiver mechanism of claim 10 wherein the fasteners are provided with an anchoring feature to engage the hitch pin, and a threaded portion spaced from said anchoring feature and passing through the apertures of said outside collet collar to engage said hex nuts. 12. The collet receiver mechanism of claim 10 wherein tightening said hex nuts on fastener threaded portions will provide force to urge said outside collet collar onto said collect receiver tube causing contact between the internal tapered surfaces of the outside collet collar and the external tapered wall surfaces of said collet receiver tube tapered flexible walls, thereby flexing said collet receiver walls onto said ball mount shank, thus centering and holding the ball mount shank in position. 13. The collet receiver mechanism of claim 12 wherein loosening the hex nuts removes said force from said outside collet collar, allowing said outside collet collar to back away from said collet receiver tube, thereby unclamping said ball mount shank, thus allowing removal when said hitch pin is removed. 14. The collet receiver mechanism of claim 10 wherein the fasteners are 2 eye bolts, said outside collet collar aperture array is 2 holes with 2 hex nuts for tensioning. 15. The collet receiver mechanism of claim 10 wherein the fasteners are 2 u bolts, said outside collet collar aperture array is 4 holes with 4 hex nuts for tensioning.
