Abstract: Disclosed is a multi-barrel rotary toy machine gun powered by compressed liquefied gas, which relates to the technical field of a replica toy machine gun, comprising: a grip assembly (1), a gun body assembly (2), and a barrel assembly (3), which are successively connected, wherein a magazine assembly (4) for loading a plurality of BB balls (5) and continuously pushing the BB balls (5) into the gun body assembly (2) via an elastic thrusting device is inserted inwardly along an entrance of the gun body assembly (3). The internal space of the barrel assembly is sufficiently utilized, which innovatively reforms the space of the central barrel of the barrel assembly to a front-mount magazine and thus significantly increases the magazine space; as such, a considerable amount of BB balls may be loaded at a single time, which significantly improves user experience and increases fun of playing.

Abstract: This invention is a motion control mechanism for use in electric toy guns. The mechanism includes a gear set, a piston set that is inside the electric toy gun's body and driven by the said gear set, a primary repositioning spring that is between the said piston set and the toy gun's rear end, and the repositioning set that is installed on the gun body, and moves backward when driven by the said piston set. The said repositioning set is fixed to the piston set, and will move backward when driven by the gear set. It will then reposition itself by the force of primary repositioning spring. The electric toy guns with this invention have the following advantageous features: Since it has a repositioning set, and air release holes, it provides for motions that are more similar to those of real guns. Thus it is more suited for military training and lasts longer.
