  • Publication number: 20170153081
    Abstract: A gun bolt assembly of air-soft pistol is disclosed to include an air cylinder, a slide carriage, a bridge member affixed to an inner rear side of the slide carriage, a piston affixed to the front side of the base of the bridge member and inserted through a rear opening of the air cylinder into the inside of the air cylinder, and a second spring positioned inside the air cylinder and the piston and axially connected between the air cylinder and the piston. Thus, the second spring will not fall off easily or wear quickly, allowing smooth displacement between the air cylinder and the piston without deviation from the accurate moving path.

  • Publication number: 20150176942
    Abstract: An electric toy gun having therein a power break control mechanism consisting of an actuator, a power break control set and a swinging block. When the clip is empty and when the trigger is pressed, the actuator is forced by a spring-loaded push rod at the bullet outlet of the clip to move the swinging block and the power break control set, causing a power break holder to be moved away from a power contact holder, and therefore power supply is disconnected, avoiding waste of power supply and component damage. The swivel rod of the power break control set has a lower rod portion. When pressed a reset button, a bottom portion of a third link of the actuator is forced downwardly against the lower rod portion of the swivel rod, returning the swivel rod to the normal front side low and rear side high position and to accurately complete the reset action.

  • Patent number: 9022014
    Abstract: An electric toy gun with a plurality of firing modes includes a trigger, a power break holder, a power contact holder, a block member slidably coupled to the power break holder and having a first tooth and a second tooth at one lateral side thereof, a swing bar having an actuation portion and a push block connected to the actuation portion. A control mechanism enables the push block of the swing bar to be shifted to the rear side of the first tooth, the rear or front side of the second tooth. Lowering of the power break holder with the block member drives the push block to move the first or second tooth forward and then to push the first tooth forward. The block member is displaced relative to the stop portion of the link which moves the power break holder.

  • Patent number: 8944041
    Abstract: A firearm firing mechanism is so configured that a hammer is retained by a front retaining block before pressing a trigger; pressing the trigger slightly at a first stage causes a main bar to bias a rear retaining block and the front retaining block backwardly at a relatively smaller angle to release the hammer in performing a single-shot action; pressing the trigger heavily at a second stage causes the main bar at a relatively longer distance so that the hammer is kept away from the front retaining block when it is returned, and the hammer is secured by the rear retaining block upon a backward displacement of a bolt and backward biasing of the hammer, and a linkage is forced to move the rear retaining block in releasing the hammer for firing when the bolt is forward again, and a continuous multi-shot firing action is performed by means of repeating this operation.
