A convertible retaining ring pliers includes a pair of jaws and a pair of handles all rotatable independently about a common pivot. Each jaw includes a transverse bore spaced from and parallel to the pivot axis for receiving an elongated cylindrical latching pin. Each handle has an associated end plate disposed on one side of the jaws, the end plates having holes to selectively receive an end of a latching pin to selectively latch a jaw to a respective handle. The latching pin bores have elongated grooves and the latching pins have associated friction springs with projecting tabs coacting with those grooves to retain the pins within the assembled pliers. Elongated retaining ring tips have hexagonal shanks received in multi-sided jaw recesses to retain the tips against rotation and to enable selected rotational orientation of the tips. The convertible pliers includes a ratchet mechanism operative between the two handles to maintain the handles closed in a selected position against the load of the retaining ring. |
