Linkage Mechanism for Control Valve in Pneumatic Nail Guns

摘要

A linkage mechanism for a control valve in a nail gun is provided. The control valve is disposed on a main body of the nail gun. A valve plug of the control valve adjoins to a safety rod of the nail gun. A trigger valve is mounted on the main body and an outer trigger is disposed adjacent to the trigger valve. An inner trigger is pivotably disposed in the outer trigger. An end of a rod member is slidably disposed at a side of the outer trigger and another end of the rod member is connected between the valve plug and the safety rod with an arm. A stopping portion is formed at a middle portion of the rod member. The stopping portion is configured for pressing the outer trigger so as to drive the inner trigger to push the rod member, the arm, the valve plug and the safety rod to move along a nail driving direction of the nail gun. The present linkage mechanism can improve a stability of controlling of nail shooting action and a durability of the nail gun.
