ABSTRACT:
A universal retaining ring tool that is shiftable between internal and external modes of operation. The tool includes a pair of pivotally connected handles, a pair of jaw members selectively coupled to the handles by a latching arrangement including two transversely slidable latch members. In one position of the latch members one handle member is coupled to one jaw member and the other handle is coupled to the other jaw member. When the latch members are switched, the one handle is coupled to the other jaw member and the other handle is coupled to the one jaw member. Removable tips are secured to each jaw member by an associated clamping plate that includes a corner that diverges from the overall plane of the clamping plate towards the associated jaw member. The fastener for securing the clamping plate is critically located so that a positive clamping force is exerted on the tip in a region where it enters the jaw. A lock lever is pivotally connected to one of the handles and provides for a locking position engaging the spring and coacting surface to lock the tool in a closed position. Where a plurality of coacting surfaces and a ratchet lever are included, a ratchet is provided which locks the relative position of the handles as they are squeezed.
