Claims

[Scope of utility model registration request]

Pushing up the concrete arm, which is disposed so as to be able to reciprocate along the nose protruding from the nailer body and whose tip is always urged to protrude beyond the tip of the nose, and the contact arm. In the nail gun, the trigger operating stem can be pushed up when the trigger lever engaged with the proximal end is pulled up, and the contact arm is a first arm that engages with the trigger lever. and a second arm part that reciprocates along the nose, and an adjustment pin rotatable around the axis between the tip of the first arm part and the base end of the second arm part. The adjustment pin is screwed onto at least the second arm, and the nailer main body is provided with a stopper member that determines the upper limit for pushing up the first arm. 1. A driving force adjustment device for a nailing machine, characterized in that the driving force can be variably adjusted by variably adjusting the push-up stroke of the second arm portion through a rotational operation.
