  • Patent number: 9261324
    Abstract: A buttstock structure is used in a toy gun, for collaborating with a gun body. The gun body includes an extension member connected to the gun body. The extension member is formed with a plurality of retaining troughs. The buttstock structure includes a buttstock body and an adjusting trigger. The buttstock body includes a chamber accommodating the extension portion, a latch selectively engaged with a respective one of the retaining troughs, and a latch recess accommodating the latch. A retaining pin is inserted in the latch and protrudingly disposed on a side wall of the latch recess. An adjusting trigger is movably connected with the buttstock body. The adjusting trigger includes a handle and a linking member connected to the handle. Two inclined slots for containing the retaining pin are formed at one end of the linking member.

  • Patent number: 7588023
    Abstract: An action structure is composed of a handle part, an action part, a tenon part, and a trajectory adjusting device. An extended handle extension seat drives a corresponding action piece through an operation of the handle, and an action piece inner tenon is located at a lower rim of the action. The action piece is fixed at a rear side through this latching effect, and at a same time, the trajectory adjusting device which is enclosed by the action piece is exposed for an adjustment of the trajectory. In addition, an action release tenon is assembled with the action piece inner tenon through an extended tenon extension rod, such that the action piece can be restored to an original position by pressing the action release tenon, thereby enabling a recoil movement of the action to achieve an effect of simulating a real gun.

  • Patent number: 7338288
    Abstract: The present invention provides an improved battery connecting structure, structured from a frontal disposed portion, an abutting joint portion and a joining portion. A movement device is configured interior of the frontal disposed portion, and conducting wires extend therefrom and connect to connecting holes corresponding to conductive contact tags of the joining portion, and turning shafts are located on the frontal disposed portion corresponding to the conductive contact tags of the connecting holes. Conducting wires further extend from connecting holes of the joining portion and connect to a power supply member. Accordingly, when a rotating movement is performed on the frontal disposed portion and the joining portion by means of the turning shafts, then the conductive contact tags of the abutting joint portion serve to realize an electric circuit, thererby achieving objectives of preventing exposing and damaging the conducting wires, and providing convenience of use and portability.
