Adjusting device for an electric nail gun

An adjusting device adapted for use in an electric nail gun, the electric nail gun including a gun body, a driving unit mounted in the gun body, a head seat connected to a front end of the gun body and formed with a nail path, and a magazine receiving a plurality of nails and connected to the head seat for moving the nails into the nail path one at a time, the driving unit being switchable between different states so as to provide different magnitudes of driving energy to perform a nail-striking operation, each of the nails having a head portion and a tip opposite to the head portion, said adjusting device comprising:

• a detecting unit including a detecting rod that is adapted to be mounted to the electric nail gun, said detecting rod having a detecting portion that is adapted for being pushed by the tip of one of the nails so that said detecting rod is rotated relative to the electric nail gun;
• a sensing unit adapted to be mounted to the electric nail gun for sensing the position of said detecting portion of said detecting rod relative to the electric nail gun, and generating a sensing signal corresponding to the position of said detecting portion of said detecting rod relative to the electric nail gun, said detecting rod being adapted to be movable relative to the head seat and said sensing unit;
• and
• an electric control unit adapted to be mounted to the electric nail gun and electrically connected to the driving unit and said sensing unit, said electric control unit switching the driving unit to one of the states corresponding to the sensing signal generated by said sensing unit.
