The cylinder body and the piston in the shell form an energy storage mechanism, and the front end of the nailing seat at the front part of the shell is provided with a telescopic gun nozzle; one side of the cylinder body is provided with a grab handle with a battery pack, one side of the gun nozzle is provided with a nail box, and the nail box is provided with a nail pusher for pushing the row nails to a nailing seat; an electric lifting mechanism for driving the piston to compress and store energy is arranged between the grab handle and the nail box, the lifting mechanism comprises a driving wheel meshed with the firing pin, and the driving wheel is in transmission connection with a motor for providing electric energy for the battery pack. When the gun nozzle is pressed down, the motor is started, the striker is driven by the lifting mechanism to drive the piston to compress air from the temporary locked preparation position, and after the striker is separated from the engagement with the lifting mechanism, the striker is released suddenly to drive the row nails of the nailing seat in the nailing box, so that the row nails are ejected from the gun nozzle.
In order to increase the amount of nails, nails wound in a roll form are generally used to be accommodated in a magazine, and how to stably convey the rolled nails to a nailing channel has been a concern.

The former obviously complicates the structure of the nailing gun, which is not only unfavorable for reducing the cost, but also has poor coordination reliability between actions such as nailing and nailing. The latter is driven by the firing pin, not only has a plurality of links of the size chain, but also the actions of releasing, striking and the like of the firing pin inevitably influence the stability and reliability of the driving of the firing pin, so that the precision of the feeding pin is poor and the failure is easy to occur.
