Firing device of toy electric pneumatic gun

The utility model relates to a firing device of a toy electric pneumatic gun and overcomes the defects that the firing device of the toy electric pneumatic gun in the prior art is complex in structure and available for single fire and continuous fire and has no other settable firing modes. According to the technical scheme, the firing device of the toy electric pneumatic gun comprises a cylinder mechanism, an electric drive mechanism, a trigger and a microcomputer control circuit. The cylinder mechanism, the electric drive mechanism, the trigger and the microcomputer control circuit are mounted on a gun shell. The firing device is characterized in that the cylinder mechanism comprises a cylinder barrel, a nozzle at the front end of the cylinder barrel, a piston inside the cylinder barrel, a piston rod at the rear of the piston, and a pressure spring located between the gun shell and the rear of the piston rod. A rack is disposed outside the piston rod. The electric drive mechanism comprises a motor, an incomp
