Due to the reciprocating movement of the piston within the cylinder,
In the case of conventional impact tools that create air pressure fluctuations in the air chamber provided between the impactor and the piston and impact the tip tool, a cavity is formed between the cylinder and the outer shell that covers it. In addition, two holes are provided on the outer periphery of the cylinder in order to communicate with the cavity a large breathing hole that allows the tip tool to transition between idle rotation and impact, and an air breathing hole that adjusts the pressure in the air chamber during tool impact. It has a heavy structure.

The purpose is to generate air pressure fluctuations in the air chamber provided between the striking element and the piston by the reciprocating movement of the piston in the cylinder, and to prevent idling and impact of the cutting edge tool in impact tools that impact the cutting tool. This is achieved by forming in the inner wall of the cylinder a large breathing groove for the transition and an air breathing groove for regulating the pressure in the air chamber during tool striking.

According to the present invention having the above configuration,
When the tip tool is pressed against the workpiece, the striker 5
closes the large breathing groove, and the striker follows the reciprocating movement of the piston to strike the tip tool. Moreover, the pressure fluctuation in the air chamber during the impact of the tip tool occurs between the large breathing groove and the impactor having an outer diameter that is discontinuous with the air breathing groove. When the tip tool is idling, the striking element moves toward the tool tip, the large breathing groove communicates with the air chamber, and the reciprocating motion of the piston is not transmitted to the striking element.
