Nail machine with effort-saving mechanism

A nail machine with an effort-saving mechanism, including:

• a shell body;
• an operating mechanism, being movably pivoted to the shell body, the operating mechanism including a pressing lever, a driving rod and a linkage, an end of the pressing lever pivoted to the shell body, an end of the driving rod pivoted to the shell body, two opposite ends of the linkage pivotally connected with the other end of the pressing lever and the other end of the driving rod respectively, the operating mechanism being operable to move between a first position and a second position;
• an actuating member, being pivoted to the shell body, a first end and a second end of the actuating member having a sliding portion and an engaging portion respectively, an end of the driving rod positionably and slidably disposed on the sliding portion;
• a striking force accumulating mechanism, including a striking board and a force accumulating member which is connected with the striking board, the striking board being movable between an initial position and a releasing position, the force accumulating member fixedly disposed on the shell body and at least partially deformably and force-accumulatably disposed in the shell body, the striking board releasably engaged with the engaging portion;
• wherein when the operating mechanism moves from the first position toward the second position, the engaging portion is engaged with the striking board, and the striking board moves from the initial position toward the releasing position;
• and when the operating mechanism is in the second position, the engaging portion and the striking board are disengaged from each other, and the striking board moves from the releasing position toward the initial position.
