In an electric handsaw with a vibration plate (11) movably fitted on a machine housing (10) and a clamp (12) for securing the saw blade (13) to the vibration plate (13), to allow the saw blade (13) to be rapidly changed without tools, the clamp (12) has two jaws (15, 16) projecting outwards from the vibration plate (11), one of which is fixed and the other is movably secured to the vibration plate (11) to adjust the spacing. The two jaws (15, 16) are connected together by a connector (20) which can be manually operated to move the movable jaw (16). Each jaw (15, 16) is fitted at its free end with a plane supporting surface (151, 161) and a clamping foot (23, 24) projecting above it which projects through an aperture (25, 26) in the saw blade (3) and the shoulder (232, 242) of which non-positively bears on a clamping bevel (251, 261) formed in the aperture (25, 26). |
