Title: Simulated shell-throwing action of toy gun mechanism

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to a simulated shell-throwing action of toy gun mechanism, and more particularly, to a simulated shell-throwing action of toy gun mechanism that is applicable to small type toy gun. 
     2. Description of the Prior Art 
     Following the trend of various refined toy guns, more rigorous requirements are demanded on the response and action when it comes to shooting. For instance, the shell-throwing action during the actual gun-shooting is an important one in the shooting process. However, since there is no expanding gas, which is generated by the combustion of the gun powder of genuine bullet, available to be used owing to lacking of genuine bullet in the conventional toy gun structure, simulated shell-throwing action and effect during the actual gun-shooting is not easy to be achieved. 
     In the gas toy gun structure, since a portion of the large type possesses relatively bigger cylinder (gun core tube) capable of containing relatively larger amount of air, one can makes use of it to derive a portion of the air to provide the toy gun with driving related simulated shell-throwing device in order to undertake required structural design for performing simulated shell-throwing action during the shooting process. However, as far as relatively small type of gas toy gun as concern, one is unable to obtain a relatively bigger cylinder (gun core tube). If one derives air from the relatively smaller cylinder to drive the related simulated shell-throwing device, the air storing amount (air pressure) will become insufficient. As a result, the normal shooting process will be affected. Therefore, just how to design a small type of gas toy gun structure having relatively small cylinder (gun core tube) that is capable of generating simulated shell-throwing action during the shooting process becomes an issue to pursue in the toy gun industry. 
     In light of the shortcoming of the gas toy gun of the prior art, the invention provides an improved simulated shell-throwing action of toy gun mechanism to be applicable in small type gas toy gun.

       FIG. 4  is a front cross-sectional view of the overall assembled structure of the toy gun mechanism of the invention showing the action when the piston compresses piston spring during gun&#39;s triggering action,  FIG. 5  is a front cross-sectional view of the overall assembled structure of the toy gun mechanism of the invention showing the action of the gun core tube during gun&#39;s triggering action,  FIG. 6  is a partial front cross-sectional view of the overall assembled structure of  FIG. 5  of the toy gun mechanism of the invention, and  FIG. 7  is a front cross-sectional view of the overall assembled structure of the toy gun mechanism of the invention showing the action when the piston spring drives the piston during gun&#39;s triggering action. As shown in  FIG. 4 ,  FIG. 5 ,  FIG. 6  and  FIG. 7 , when it comes to operation, the trigger ( 15 ) is pressed down to start the motor ( 51 ), then the transmission gear set ( 52 ) and the piston ( 32 ) are sequentially driven to compress the piston spring ( 34 ) (as shown in  FIG. 4 ), afterward, the gun core tube ( 31 ) is driven to slide toward the circumferential flange ( 331 ), and the restoring spring ( 312 ) is then stretched making the gas nozzle ( 311 ) is retreated within the through hole ( 13 ) (as shown in  FIG. 5 ) to facilitate the loading of the plastic bullet to front part of gas nozzle ( 311 ) or through hole ( 13 ) (not shown in the Figure).
