Claim:
A nail gun comprising a housing including an extending handle being in an angular position relative to the housing, a first locking element having a first projection, a second locking element opposing the first locking element and having a second projection, and an elongated sliding groove extending out of the housing, a safety mechanism including an actuation member mounted in the sliding groove, the actuation member having a nose at a free end thereof, and a nail alignment adjustment mechanism comprising: a lever having one end pivotably secured to the housing; a spring having a first end secured to the other end of the lever and a second end affixed to the actuation member; and a spring-biased selector including a shank passing through the lever, and a knob secured to an open end of the shank, the knob having a lock member, whereby disengaging the lock member from the first projection of the first locking element at a first position and pivoting the knob to a second position to lockingly engage the lock member with the second projection of the second locking element will cause the nose to contact a first workpiece; and whereby disengaging the lock member from the second locking element at the second position and pivoting the knob to the first position to lockingly engage the lock member with the first locking element will cause the nose to dispose above a second workpiece and align a nail with a through hole of the second workpiece.
