Abstract

A gas combustion type hammering tool, wherein a motor storage part (22) is formed in the upper wall of a combustion chamber (11). The shaft (21) of a motor (20) is coupled to a rotating fan (18) facing the combustion chamber (11) through the bottom part of the storage part (22). A mixed gas obtained by mixing gases by the rotating fan (18) is ignited and burned in the combustion chamber (11). A fastener is hammered by the pressure of combustion gas produced by the combustion. The motor (20) is stored in the storage part (22) through short cylindrical elastic damping bodies (25) and (26) installed on the upper and lower parts thereof. A plurality of groove holes (28) longer in the vertical direction are formed in the damping bodies (25) and (26) at prescribed intervals along the circumferential direction.

Description

technical field

[0001] The present invention relates to a motor holding mechanism of a gas combustion type driving tool, which ignites a mixed gas obtained by mixing combustible gas and air by a rotating fan driven by a motor in a combustion chamber formed above an impact cylinder to make it Combustion uses the pressure of the combustion gas generated by the combustion to drive the impact piston housed in the impact cylinder, and impacts the fasteners such as nails placed below it with a driver integrated with the impact piston, Thereby performing nailing and other operations. Background technique

[0002] As an example of a gas combustion type driving tool, a gas combustion drive driver is known. In the gas combustion drive driving machine, inject combustible gas into the closed combustion chamber, stir the mixture of combustible gas and air in the combustion chamber, and the stirred mixed gas burns in the combustion chamber to generate high-pressure combustion gas in the ...
