The disclosure relates to tools and more particularly pertains to a new tool for installation and removal of snap rings.
An embodiment of the disclosure meets the needs presented above by generally comprising a frame that comprises a pair of members. The members are opposing, such that a first end of one member opposes a second end of the other. Each of a pair of first holes is positioned through a respective member proximate to the first end. Each of a pair of rods is fixedly coupled to a respective member proximate to the second end. The rod is slidably positionable through an opposing first hole. A biaser is operationally coupled to each member. Each of a pair of first tips is coupled to and extends from a first side of the frame. The frame positions the first tips for insertion into the complementary orifices of the snap ring. The biaser is positioned to diverge and converge the members to respectively widen and narrow the snap ring.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, 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 an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure 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 disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
