Gas combustion type striking machine

摘要

In a gas combustion type striking machine, a combustion chamber is opened and closed by moving a movable sleeve in a vertical direction. A safety lever is attached to a trigger, and a switch is switched by being pressed by a switch lever arranged to be engageable with the safety lever. A hold member which is engageable with the movable sleeve is rotatably connected to the trigger. A shaft supporting a base end of the hold member positions between a shaft supporting the switch lever and a cylinder in a right-left direction which is perpendicular to the vertical direction.

主权项

1. A gas combustion type striking machine comprising:
a body; a cylinder arranged in the body; a piston arranged slidably in a vertical direction in the cylinder; a movable sleeve arranged in an upper portion of the cylinder; a combustion chamber which is opened and closed by moving the movable sleeve in the vertical direction; a nose portion arranged in a lower side of the body and from which a nail is driven out; a contact member projecting from the nose portion to be slidable in the vertical direction and configured to upwardly move with respect to the body by being pressed against a workpiece so as to move the movable sleeve in a closing direction to close the combustion chamber; a trigger; a safety lever pivotally supported on a shaft fixed on the trigger and arranged to be moveably linked to the movement of the contact member via a torsion coil spring supported on the shaft fixed on the trigger, wherein the safety lever is configured to be engaged with the trigger directly; a switch lever arranged to be engageable with the safety lever; a switch disposed above the trigger and configured to be switched by being pressed by the switch lever; and a hold member rotatably connected to the trigger and arranged to be engageable with the movable sleeve.
