<p>A nailing gun includes a swing arm (31) having a first end (310) pivoted to a frame (21), and a second end (311) movable between a first position proximate to a flywheel (22) to drive a hammer rod (32) to hit a nail, and a second position distal from the flywheel (22). A spring plate (44) has a spring end portion (4442) resiliently supporting the second end (311) of the swing arm (31). A stop member (42) limits the spring end portion (442) and the second end (311) of the swing arm (31) from moving relative to the frame (21). When a safety member (45) is subjected to an external pressure, the stop member (42) permits the second end (311) of the swing arm to move together with the spring end portion (442) to the first position. The spring end portion (442) can stably retain the second end (311) of the swing arm (31) at the second position in case of no external pressure.
