Abstract: An electric nail gun using an air spring, the driving mechanism thereof including a working cylinder, a pneumatic cylinder, an air storage chamber, a nailing component, a lifting device, a one-way component, a latching device, a separating device and a guiding component. The nailing component has a first longitudinal edge to cooperate with the lifting device and a second longitudinal edge to cooperate with the latching device and the separating device. The first longitudinal edge has several discontinuous and protruding faces separated apart from one another and cooperating with cylindrical and protruding pins of the lifting device. The second longitudinal edge has a latching groove to cooperate with the latching device, the latching groove corresponding to a detaching section for a cam of the lifting device.
