ABSTRACT:
A power tool (2) has a first body (6), a second body (4) connected to the first body (6), and a locking mechanism. One of the bodies (4;6) is moveable with respect to the other body (4;6). The locking mechanism is capable of locking the movement of the one body (4;6) with respect to the other body (4;6). The locking mechanism is a two part system having a first part, a locking member (119), and a second part, receiving member (82). Engagement between the first part and the second part locks the first body (6) and the second body (4) against movement with respect to each other. One part is moveable with respect to the other part between a first position and a second position. The first part and the second part are engaged when the one part is in the first position. The first part and the second part are disengaged when the one part is in the second position. At least one of the parts is shaped to cause play between the two parts of the locking mechanism to be taken up when the one part moves into the first position.
