air tools

Abstract

The objective is to provide an air tool that operates by operating an opening / closing mechanism in a direction different from the direction of movement of the valve piston of the air valve. [Solution] The air tool of the present invention is an air tool in which a drive unit is operated by compressed air, and comprises a tool body having an air valve arranged in a supply path for compressed air to the drive unit, and an opening / closing operation unit for opening and closing the air valve, wherein the air valve has a valve piston that opens and closes the air valve by reciprocating between a closed position and an open position, and the opening / closing operation unit moves in a second direction that intersects with a first direction which is the direction of movement of the valve piston, thereby causing the valve piston to move from the closed position to the open position.

Claims

1. An air tool in which the drive unit is operated by compressed air, The tool body comprises an air valve positioned in the supply path of compressed air to the drive unit, and an opening / closing operation unit for opening and closing the air valve. The aforementioned air valve has a valve piston that opens and closes the air valve by reciprocating between a closed position and an open position. As the opening / closing operation unit moves in a second direction perpendicular to the first direction which is the direction of movement of the valve piston, the valve piston moves from the closed position toward the open position. The rotational speed of the drive unit changes as the opening / closing operation unit moves in the second direction. Air tools.

2. It includes an inclined portion that extends in a direction inclined with respect to the first direction, The air tool according to claim 1, wherein the inclined portion moves in conjunction with the movement of the opening / closing operation portion, thereby pushing the valve piston in the first direction.

3. The air tool according to claim 2, wherein the direction in which the inclined portion extends is less than 45° with respect to the direction of movement of the inclined portion.

4. The air tool according to claim 2, further comprising a connecting portion that connects the opening / closing operation portion and the inclined portion, which are arranged at a distance from each other.

5. The air tool according to any one of claims 1 to 4, further comprising a locking mechanism for releasably locking the opening and closing operation section.
