| (54) | Releasable locking mechanism | 
| (57) Releaseable mechanism for a power tool includes first (2) and second (12) members
                     which may be coupled together in selective orientations. The coupling of the members
                     (2) (12) is achieved without the need for separate tools by way of co-operation between
                     manually operable detent (24) and at least one locking member (18). The advantage
                     provided by this arrangement is that the need for separate coupling tools is obviated. |
