<p>A mitre saw comprising: a base (2); a round table (4) rotatably mounted on the base (2); an extension arm (6) rigidly connected to the periphery of the round table (4) and which extends radially away from the axis of rotation of the round table (4); a saw unit mounted on the round table (4) for cutting work pieces located on the round table (4) or extension arm (6); a locking mechanism for angularly locking the position of the round table (4) relative to the base (2) to prevent rotation of the table (4) relative to the base (2); the locking mechanism comprises a locking member (28) mounted on the extension arm (6) in such a manner that it can: be linearly slid in relation to the extension arm (6) from a first position where a first engaging part (30,62) of the locking mechanism is disengaged from the base (2) to a second position where it engages a part of the base (2) in order to prevent relative movement between the extension arm (6) and the base (2), or vice versa; and be pivoted in relation to the extension arm (6) from a first position where a second engaging part (46) of the locking mechanism is disengaged from the base (2) to a second position where it engages a part of the base (2) to prevent relative movement between the extension arm (6) and the base (2), or vice versa. <IMAGE></p> |
