Retaining ring e.g. circlip, positioning or extracting tool i.e. plier, for gear box, has retaining unit formed by head and shoulder for retaining expansion of ring, where unit defines housing to receive all or part of ring

摘要

The tool has a lever arm (6) for expanding a retaining ring, and a support unit i.e. U-shaped body (8) for supporting the lever arm to cause the expansion of the ring. A retaining unit formed by a head (10) and a shoulder (10a) retains the expansion of the ring, where the retaining unit defines a housing (10b) to receive all or a part of the retaining ring to be placed or extracted. The shoulder forms a wall (10c) of the housing to retain the expansion of the ring, where the shoulder forms a stop for stopping the expansion of the ring.
