1. A fastener striking tool, comprising:
a shell, which is configured to place a compression chamber with gas storage and a cylinder body with a piston inside, and the shell is fixedly connected to a holder;
the holder, which is configured to support a driving wheel driven by a motor, and provided with a nailing base of which a front end is provided with a gun nozzle, so as to form a nailing passage extending to the gun nozzle from the cylinder body;
a striker, which is provided with a first end and a second end and in driving meshing with the driving wheel, the first end is connected to the piston, and the second end extends to the nailing passage along the gun nozzle direction, so as to move back and forth between a compression limiting position and a nailing limiting position;
wherein the fastener striking tool further comprises:
a separating structure, which is located around the compression limiting position at the second end of the striker, so as to seal a side clearance between the striker and the nailing passage,
wherein one end, adjacent to the gun nozzle, of the nailing base, is provided with nail containing chamber communicating with the nailing passage, and one end adjacent to the piston is provided with an abdicating chamber capable of containing a striker ratchet;
wherein a separating wall is disposed between the abdicating chamber and the nail containing chamber, and the separating wall is provided with a circular through hole adapting to a cylinder at a front section of the striker, so as to form a separating structure.
