     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 5 thereof, a new and improved locking ring tool embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     FIG. 1 illustrates a prior art locking ring tool 1 utilizing support posts operative through relatively manipulatable levers 3 to mount a locking type ring or circlip, in a manner as set forth in U.S. Pat. No. 4,776,245. Further, the locking ring tool, as illustrated in FIG. 2, sets forth a pivot structure to mount support post 5 relative to operative handle 7, wherein the post 5 may be switched relative to the handle 7 to permit selective spreading or contracting of an associated locking ring, in a manner as set forth in U.S. Pat. No. 4,625,379. 
     More specifically, the locking ring tool 10 of the instant invention essentially comprises an elongate fixed leg 11, including a first leg portion 11 defined by an elongate channel 12. The elongate channel 12 includes a second leg portion 13 oriented generally orthogonally and upwardly relative to the first leg portion 12. A third leg portion 14 is integrally mounted to the second leg portion 13 and defines an acute included angle 15 therebetween. The third leg portion 14 terminates in a first support pin 16 that is oriented parallel to a longitudinal axis defined by the second leg portion 13. A first pivot leg 17 includes an adjusting link 18 mounted to a first pivot 19 adjacent a forward end of the first pivot leg 17, with an arcuate adjusting link heel 20 formed at a rear terminal end of the adjusting link 18 spaced from the first pivot 19 to cooperate with a forward end of adjusting screw 22 that is threadedly mounted within an elongate channel of the first leg portion 12 to effect adjustment of the first pivot leg 17 relative to the first leg portion 12. A release link 21 is mounted to a second pivot 23 spaced from the first pivot 19 to effect subsequent release of the spaced jaws. The first pivot leg 17 is pivotally mounted at its forward end through a third pivot 24 to a second pivoted leg 25. The second pivoted leg 25 pivots from a first position, as illustrated in FIG. 3, wherein the second pivoted leg 25 and the second leg portion 13 are generally aligned relative to one another to a second position to define an acute included angle between the second leg portion 13 and the second pivot leg 25. A projecting leg 26 defines an acute angle 30 between a projecting leg 26 and the second pivot leg 25, with a second support pin 28 fixedly mounted at a forward terminal end of the projection leg 26 for alignment and contiguous contact with the first support pin 16 when the third leg portion 14 and the projecting leg 26 are in the first position, as illustrated in FIG. 3. A fourth pivot 27 pivotally mounts the second pivot leg 25 to the fixed leg 11 at a junction of the second leg portion 13 and the first leg portion 12, with a return spring 29 biasing the third leg portion 14 and the projecting leg 26 to the first position. If desired, a conically beveled first forward end 16a and a second conically beveled forward end 28a may be formed to the forward terminal ends of the first and second support pins, as illustrated in FIG. 5 for example. 
     In this manner, the support pins may be spread and fixed in desired spread configuration to spread an associated locking ring &#34;C&#34; relative to a mounting structure for securement to such mounting structure, or alternatively removal therefrom. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
