Electric nail gun

An electric nail gun, comprising:

• a gun body;
• a muzzle unit that is connected to said gun body, and that defines a nail-striking channel extending along an axis;
• a magazine unit that is connected to the muzzle unit, and that includes a nail magazine adapted for accommodating a plurality of nails arranged in a row, and a magazine pusher movably mounted in said nail magazine, adapted for pushing the plurality of nails sequentially into said nail-striking channel, and including a protrusion;
• a power unit that is mounted to said gun body and that is adapted to strike the plurality of nails in said nail-striking channel during a striking cycle;
• a control unit that is mounted to said gun body, and that includes a trigger switch configured to output a start signal when being triggered, a trigger operable to trigger said trigger switch, a safety switch configured to output a safety signal when being triggered, and a controller electrically connected to said trigger switch and said safety switch, and configured to initiate the striking cycle upon receipt of the start signal and the safety signal;
• and
• a safety unit that is movably mounted between said gun body and said muzzle unit along the axis, and that includes a first safety member movable along the axis, and a second safety member disposed between said safety switch and said first safety member along the axis, and movable between a linked position, where said second safety member is spaced apart from said protrusion of said magazine pusher, is co-movable with said first safety member, and triggers said safety switch when being moved toward said safety switch, and a delinked position, where said second safety member is pushed by said protrusion and is movable relative to said first safety member along the axis such that movement of said first safety member does not move said second safety member.
