US12276475 - Toy gun and gas cylinder piercing structure thereof

The patent describes a toy gun featuring a gas cylinder piercing structure that includes a screw base with a circular through-hole and a movable push rod unit equipped with a striker pin. The design allows for the push rod to either seal the through-hole or create an air vent channel depending on the engagement of an engagement lug with a slot on the annular block.
