Abstract
A pneumatic nailing machine having a driving depth adjusting mechanism disposed near a trigger. A push lever is vertically movably supported around a nose portion and extends near the trigger. The push lever is divided into an upper section and a lower section, the dividing portion being near the trigger. A cam shaft having first and second cam lobes are rotatably provided near the trigger. A lowermost end of the upper section is in slide contact with the first cam lobe, and an uppermost end of the lower section is in slide contact with the second cam lobe. The cam shaft together with the cam lobes, and the upper and lower sections are concurrently movably supported by a guide plate supported by a main body. By rotating the cam shaft in one direction, a distance between the lowermost and uppermost ends is increased to expand entire length of the push lever.
