1. An electric nail gun comprising:
a cylinder unit defining a cylinder space, and a gas space that communicates with said cylinder space and that is adapted for storing gas;
a nail-striking unit including a piston assembly that extends through said cylinder space, that is movable in a first direction, that is adapted for striking a nail, and that is able to be driven by pneumatic power and electric power, the gas space being isolated from the external environment when said nail-striking unit strikes the nail;
a valve unit including
a valve that is disposed between said cylinder space and said gas space, and that is movable among a closed position, in which said valve closes said cylinder space such that the gas in said gas space is refrained from entering said cylinder space, and a plurality of open positions, when said valve is in any one of the open positions, said valve cooperating with said cylinder unit to define an opening that is adapted for the gas to flow from said gas space into said cylinder space, a dimension of said opening in the first direction when said valve is in one of the open positions being different from the dimension of said opening when said valve is at another one of the open positions, and
a pushed rod that is connected to said valve, that extends through said cylinder unit, and that is movable relative to said cylinder unit in the first direction; and
a muzzle unit including
a nail gun seat that is connected to said cylinder unit, and that is adapted for loading the nail,
a safety assembly that is mounted to said nail gun seat, that is movable relative to said nail gun seat in the first direction, and that has
a first end adapted to be pressed and moved by an object,
a second end, when said first end is not pressed against the object, a distance between said second end and said pushed rod in the first direction being defined as a first actuating distance, when said first end is moved by the object, said pushed rod being urged to move by said second end such that said valve moves from the closed position to one of the open positions, and
a plurality of positioning portions arranged in the first direction, each of said positioning portions being configured to be a hole, and
an adjusting assembly that includes a spring and a fastener member which removably engages one of said positioning portions, and that is operable to be separated from the one of said positioning portions to engage another one of said positioning portions so that the first actuating distance is adjusted.
