An electric toy gun includes a gun body carrying a piston set and a gear set having a first gearwheel provided with a side pin and rotatable to move the piston of the piston set, the gear set is arranged above the axis of movement of the piston of the piston set, a backlash vibration mechanism for producing a backlash vibration when the electric toy gun fires a bullet, and an attached cartridge carrier, which simulates the cartridge feeding operation of a real gun. The backlash vibration mechanism includes a connection block arranged on the axis of movement of the piston of the piston set, a weight fixedly connected to the bottom side of the connection block beneath the axis of movement of the piston.

1. Field of Invention
The present invention relates to electric toy guns and more particularly, to such an electric toy gun, which is equipped with a backlash vibration mechanism, which causes the electric toy gun to produce a backlash vibration when firing a bullet and is so arranged to assure operation stability of the electric toy gun, and an attached cartridge carrier, which simulates the cartridge feeding operation of a real gun when the user triggers the electric toy gun.
2. Description of Related Arts
FIG. 1 is a schematic sectional side view of an electric toy gun according to the prior art.
FIG. 2 illustrates the structural arrangement of a backlash vibration mechanism of another design of electric toy gun according to the prior art.
FIG. 3 is a perspective view, partially exploded and partially enlarged, of an electric toy gun in accordance with the present invention.
Referring to FIG. 3, an electric toy gun in accordance with the present invention is shown comprising a gun body A. The gun body A, as shown in FIG. 4, comprises a gear set 1, a piston set 2, a backlash vibration mechanism 3, and an attached cartridge carrier 4, which is arranged at the top side relative to the piston set 2.
The gear set 1 comprises a first gearwheel 11 (see FIG. 5) rotatable by an electric drive 12 (for example, electric motor). The first gearwheel 11 comprises a gear sector 111 disposed above and meshed with the piston set 2 and rotatable to move a piston 21 of the piston set 2, and a pin 112 perpendicularly extended from one side thereof near the periphery. Further, the gear set 1 is disposed above the axis of movement of the piston 21 of the piston set 2.
The piston set 2 comprises the aforesaid piston 21 (see FIG. 5), and a piston spring 22 attached to the piston 21. The piston spring 22 is compressed when the piston 21 is moved backwards by the gear sector 111 of the first gearwheel 11. When the first gearwheel 11 is rotated to a predetermined position, the gear sector 111 is disengaged from the piston 21, and the piston spring 22 is released from the constraint to push the piston 21 back to its former position (see FIG. 6). Further, a gun barrel 5 is provided at the front side of the piston set 2 (see FIG. 4).
