摘要： A combustion-type power tool includes a housing, a cylinder, a cylinder head, a combustion chamber frame, and a rotatable fan. The combustion chamber frame including a base section, a head section abuttable on the cylinder head to provide a combustion chamber when the combustion chamber frame is at a first position, and a connection portion for connecting the head section with the base section. The fan includes fan blades which define a widthwise center line and having widthwise edge portions which define a widthwise edge line at a side of the cylinder head. The widthwise center line is offset from the connection portion toward another end of the housing, and the widthwise edge line is offset from the connection portion toward the cylinder head when the combustion chamber frame is at a second position.
