    • The present invention relates to a keyless blade clamp mechanism including a base (4), a sliding block (6) slidably disposed on the base (4) and a clamping lever (11) pivotally connected on the base (4). On one pivot side of the clamping lever (11) is a clamp plate (7) and on the other pivot side of the clamping lever (11) is a plate (3). The base (4) has a supporting surface (12) opposing the clamp plate (7). In use, the sliding block (6) slides to engage and press the plate (3) causing the clamp plate (7) to pivot and a gap to appear between the clamp plate (7) and the supporting surface (12) to permit a saw blade (9) to be inserted into (or be pulled out of) the gap. The present invention has the advantage that few components are involved and it is easily manufactured at low cost.
