Abstract: A pneumatic nailing machine includes a piston and driver assembly movably disposed in a striking cylinder for driving a fastener out of a front end of a main housing when primary pressured air is supplied to the cylinder, a head valve forced open when an active pressure generated as a result of flow of the primary pressured air is higher than a counter pressure in a counter-pressure zone, and an air valve unit convertible, in response to a throttling action applied to supply of secondary pressured air into the counter pressure zone, between a led-through state, where the head valve is kept unmoved in a closed position, and a shut-off state, where the flow of the secondary pressured air is disrupted thereby forcing the head valve forced open.

Abstract: A nailing depth adjustable device for a nail gun includes: a barrel-extending part mounted slidably on a barrel; an interconnecting part extending from the barrel-extending part and defining a driving surface; a support; and a telescopic adjusting unit mounted movably on the support and including a first part and a second part that is coupled movably to the interconnecting part, that defines a driven surface, and that engages threadedly the first part so as to be rotatable relative to the first part and the interconnecting part and therefore to be movable relative to the first part and the interconnecting part, thereby permitting adjustment of the distance between the driving and driven surfaces.
