COMBUSTION GAS NAILING MACHINE

摘要

A combustion gas nailing machine has a lockout bar (31) connected at one end to a movable sleeve (12), a cam member (32) provided opposite the other end of the lockout bar (31) and capable of rotating in conjunction with a trigger mechanism (27), a cam surface (34) formed on the cam member (32) and in contact with the lower end of the lockout bar (31) to hold the movable sleeve (12) in a state where a combustion chamber (6) is closed, and a step section (44) formed on the cam surface (34) and is capable of engaging with the lockout bar (31). When the cam surface (34) holds the movable sleeve (12), the step section (44) engages with the lockout bar (31) to prevent the cam member (32) from pivoting, and this prevents the trigger mechanism (27) from being operated to a position at which a combustible gas is ignited.
