Bullet rotatably shooting apparatus in a toy gun

Abstract

A bullet rotatably shooting apparatus in a toy gun includes a rotating tube, a driving mechanism and a firing mechanism. The rotating tube has a central axis, and the rear end of the rotating tube is rotatably connected with a limiting tube fixed with a rotating tube shell. The rotating tube is positioned in the rotating tube shell. The driving mechanism drives the rotating tube to quickly rotate around a central axis. The firing mechanism is arranged at the rear end of the rotating tube, which fires bullets to rapidly pass through the rotating tube. The bullets cooperate with the rotating tube by friction and can slide rapidly along the central axis in the rotating tube and can rotate rapidly driven by the rotating tube, so that the bullets can be fired in a rapidly rotating state.

         10 . The bullet rotatably shooting apparatus in a toy gun according to  claim 1 , wherein firstly, said bullet is pushed into said rotating tube; then, said driving mechanism is started to drive said rotating tube to rotate, said bullet is rotated driven by said rotating tube; finally, said firing mechanism is started so that said bullet flies out of said rotating tube in a rotating state. 
     
     
         11 . The bullet rotatably shooting apparatus in a toy gun according to  claim 1 , wherein firstly, said driving mechanism is started to drive said rotating tube to rotate; then, said bullet is pushed into said rotating tube, and said rotating tube drives said bullet to rotate; finally, said firing mechanism is started so that said bullet flies out of said rotating tube in a rotating state. 
     
     
         12 . The bullet rotatably shooting apparatus in a toy gun according to  claim 1 , wherein said firing mechanism comprising an air cylinder with a piston, said piston and said air cylinder are sliding and sealing connection; a piston rod of said piston is sleeved with a spring, a top of said piston rod is provided with a gun handle, said spring is against said piston at one end and against said gun handle at the other end.
