Abstract (en)
[origin: WO2016115705A1] A power tool for driving a fastener includes a cylinder (50) and a drive piston (54) within the cylinder (50), the drive piston (54) being acted on by a driving force resulting from a pressure difference, the drive piston (54) being moveable between an initial position and a driving position. The power tool further includes a drive blade (42) coupled to the drive piston (54) and operable to drive a fastener and a locking mechanism (300) that operates through engagement between at least two catches (306, 308) and at least two locking members (304, 305). By adopting such a double-action locking mechanism (300), the power tool is significantly safer than the common general power tools for driving a fastener.
