Combustion-type power tool

摘要

In a combustion-type power tool (2), when a safety unit (231) is pressed against a workpiece (W) to cause a valve sleeve (22) to close a combustion chamber (210), a power region (62) of a lever (60) is actuated to permit a weight region (63) of the lever (60) to displace a holding member (5) holding a fuel canister (24) from a normal position to a pressed position. When the holding member (5) is in the pressed position, a valve stem (241) of the fuel canister (24) is forced into pressing engagement with an intake port (263) of a fuel canister actuation unit (26) to permit delivery of a measured dose of fuel to the combustion chamber (210) through the intake port (263).
