1. An electric nail gun, comprising a main body, a limiting mechanism, an active mechanism, a passive mechanism, a magnetic attraction mechanism, a striking nail mechanism, a safety mechanism and a lithium battery case, wherein:
the main body includes a housing section, a handle section, a buttstock section, and a nail magazine section, wherein: (i) the handle section is connected to both the housing section and the buttstock section, (ii) the handle section includes a holding area and a trigger area adjacent to each other, with a motor switch and a trigger switch being disposed, respectively, at the holding area and a trigger area, (iii) the housing section has frame plates spaced and arranged therein, (iv) one end of the housing section is assembled with a head assembly, (v) the nail magazine section is connected to the head assembly and the buttstock section, and (vi) the buttstock section is provided with a power switch;
the limiting mechanism includes an initial rod and a terminal rod spaced from each other and disposed between the frame plates, the terminal rod being closer to the head assembly than the initial rod;
the passive mechanism is located between the frame plates and includes a pulley, a steering wheel, and a belt, wherein the belt is wrapped around the steering wheel and the pulley and in contact with and engaged with the pulley;
the magnetic attraction mechanism includes an electromagnet and a cam, wherein (i) the electromagnet is assembled on an outer side of the frame plate and located at a plate hole of the frame plate, (ii) the cam is pivotally disposed in a groove of the pulley, with a wheel hole being disposed at a bottom of the groove and corresponding to the plate hole of the frame plate and a magnetic attraction end of the cam, and (iii) the electromagnet generates magnetic force during operation, attracting the magnetic attraction end of the cam to pivot towards the plate hole and thus causing a protruding end of the cam to partially protrude outside the groove;
the active mechanism is located within the housing section of the main body and includes a motor and a wheel driven by the motor for rotation, wherein the wheel features a driving block that faces the pulley and has a impact face able to contact the protruding end outside the groove, thus allowing the wheel to initiate rotation of the pulley from an initial state;
the striking nail mechanism includes a fixed seat and a striker, wherein (i) the fixed seat is secured on the belt and located between the initial rod and the terminal rod, (ii) the striker has one end fixed at the fixed seat and the other end facing towards the head assembly, and (iii) the fixed seat of the striking nail mechanism is movable from an initial position at the initial rod to a nailing position at the terminal rod;
the safety mechanism is disposed at the head assembly and includes a safety switch and a safety slider; and
the lithium battery case is connected to the buttstock section and provides electrical connections to the motor, the electromagnet, the power switch, the motor switch, the safety switch and the trigger switch.
