Abstract: The self-test fire control system for a toy gun includes a power unit and a control unit connected to the power unit and configured with a self-test software application. The power unit includes a power module and a driver module. The control unit includes a voltage monitor module, a regulator module, an indicator module, a fire mode selection module, and a trigger ON/OFF module. Before the toy gun is operated, the control unit may test the circuit switches, the gear set, and the battery so as to see if there is an incompatibility between or anomaly in the motor, spring, battery, or gear set. As such, corrective actions or repairs may be performed and the reliability of the toy gun is enhanced.

Abstract: The buttstock for an electric air gun contains a main unit, an extension unit configured to a front end of the main unit, a detachable and adjustable butt unit configured to a rear edge of the main unit, and a cheek support unit that can be raised or lower along a top edge of the main unit. The extension unit can be telescoped out of the main unit and the butt unit can also be extended backward for different distance so as to suit users of various arm lengths. The cheek support unit on the other hand can be raised to various heights so that users of different neck lengths can more comfortably operate the electric air gun.

Abstract: A percussion and magazine revolving device of toy grenade launcher includes a magazine. The magazine forms annularly arranged cylindrical accommodation chambers receiving therein grenades and has a circumference along which holding pegs are arranged. A release plate is attached to the magazine and forms a pawl for selective engagement with the holding pegs. A trigger and a percussion mechanism coupled to the trigger are arranged on a carrier seat. The percussion mechanism has a top edge o which a drive bar is mounted. The magazine is rotated to compress an elastic element arranged therein. When the trigger is pulled, the percussion mechanism is caused to fire one grenade, and at the same time, the drive bar pushes the release plate away to make the pawl disengaging the holding pegs, thereby allowing the magazine to rotate an angle for being ready to fire the next grenade.

Abstract: A grenade for toy gun generally includes a bullet compartment having multiple circumferentially arranged accommodation cylinders to receive BB bullets or paintballs therein, a storage chamber forming circumferential raised walls, and an actuation rod assembly that is hollow and has a front end forming an air inlet opening in which a check valve is mounted and a rear end forming an air output opening and circumferential gasket rings. The gasket rings are respectively set in engagement with the raised wall to hermetically seal the storage chamber. Compressed air is fed through the air inlet opening and is discharged through the air output opening to accumulate in the storage chamber. In percussion, the actuation rod assembly is caused to move forward to disengage the gasket ring from the raised wall so as to release the compressed air to instantaneously eject the BB bullets or paintballs received in the bullet compartment.
