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.

Abstract: A fire control device for a toy gun and a method therefor are provided. The device includes a trigger switching module, a firing mode selecting module, a control module, a power module and a motor module. Through a selection via the firing mode selecting module, the control module can control the time that the power module supplies the motor module, so that the lasting time period that the motor module drives a firing module to fire can be controlled, thereby multiple firing modes, single fire, 3-round burst, continuous fire and weapon safety, can be achieved.
