  • Patent number: 11953282
    Abstract: A simulated shaking bullet chain type toy gun equipped with a bullet chain is provided. The toy gun includes a gun body, an actuated member, and a bolt assembly and a reciprocating assembly both reciprocatingly disposed in the gun body. The reciprocating assembly is linked to the bolt assembly and has a trigger portion reciprocating with the reciprocating assembly to produce a moving path. The actuated member is installed in the gun body and located on the moving path, and connected to the bullet chain. The reciprocating assembly reciprocates to trigger the actuated member by the trigger portion, and the actuated member links the bullet chain to shake, so as to achieve a high degree of simulation of the shaking effect of the bullet chain.

  • Patent number: 11454472
    Abstract: The no-bullet no-firing structure of the toy gun is disclosed. The toy gun has an impact unit and the no-bullet no-firing structure. The structure has a barrel component, a switch unit and a magazine unit. The switch unit has a pull lever with an abut lever, an elastic member with an elastic arm, and a push member. The magazine unit has a magazine, a bullet and a pulled member. The pulled member is pushed by the bullet to push the abut lever to make the pull lever, the push member and the impact unit be aligned on a same linear line. When no bullet is in the magazine, the abut lever is pushed by the elastic arm to rotate the pull lever pivotally, and the pull lever drives the push member to swing to make the toy gun be unable to fire.
