ABSTRACT:
A nailing depth adjusting mechanism for a pneumatic nail gun is described. The mechanism includes a firing control strip fastened to the gun body which releases the firing pin of the pneumatic nail gun. The firing control strip has two parallel lugs and a toothed adjusting wheel disposed between the lugs. The wheel has a longitudinal axially internally threaded hole and holes are provided in the lugs. A safety bar is provided having a threaded rod at one end. The rod is inserted through the lugs and threadedly received in the hole in the adjusting wheel. The end extending from the wheel is received in a socket which, in turn, is received in a hole through one lug. A compression spring is provided between the adjusting wheel and the opposite lug. Rotation of the wheel then displaces the threaded rod within the mechanism and, in turn, moves the safety bar.
