Three-mode toy gun

A three-mode toy gun, comprising:

• a gun shell;
• a firing cylinder assembly, wherein the firing cylinder assembly comprises a loading cylinder, an air cylinder and a piston member, the loading cylinder is fixed to the gun shell, the air cylinder is slidably connected to the loading cylinder, the piston member is slidably connected to the air cylinder, the piston member has a first rack and a push-down plate, the push-down plate has a push-down bevel, the air cylinder has a second rack, and a first elastic member is provided between the piston member and the gun shell;
• a transmission gear train, wherein an output end gear of the transmission gear train has a first incomplete gear and a second incomplete gear, the first incomplete gear is engageable with the first rack, and the second incomplete gear is engageable with the second rack;
• an electric drive mechanism, wherein the electric drive mechanism comprises a motor and a power supply cable, the motor is in transmission connection with an input end gear of the transmission gear train, the power supply cable is electrically connected with the motor, and the power supply cable has a first switch and a second switch connected in series;
• a mating member, wherein the mating member is movably arranged in the gun shell, the mating member has a first position, a second position and a third position, in the first position the mating member is located in line with the piston member, and the mating member located at the second position does not interfere with the piston member, the third position is located on a side where the second position is away from the first position, the mating member has a mating bevel, a third elastic member is provided between the mating member and the gun shell, the mating member has a lower convex rib and an upper convex rib, and an avoidance groove is formed between the lower convex rib and the upper convex rib;
• a trigger mechanism, wherein the trigger mechanism is arranged in the gun shell, the trigger mechanism has a trigger and a convex bar, the trigger and the convex bar are rotatably connected, a second elastic member is provided between the trigger and the convex bar, and both ends of the second elastic member abut against the trigger and the convex bar respectively, a fourth elastic member is provided between the trigger and the gun shell, an upper edge of an inner side of the convex bar is provided with an inner convex rib, a groove width of the avoidance groove is greater than a width of the inner convex rib, and an end portion of the lower convex rib has a smooth outer convex arc surface;
• a mode adjustment plate, wherein the mode adjustment plate is movably arranged in the gun shell, and two guide ribs are provided on the gun shell, the mode adjustment plate is slidably arranged between the two guide ribs, and the mode adjustment plate is movable along the guide ribs to adjust the mating member to the first position or the second position;
• a rotating member, wherein the mode adjustment plate has an adjustment groove and a plurality of guide grooves, a plurality of guide posts are provided on the gun shell, and each of the guide posts is respectively inserted into a corresponding guide groove, and the rotating member is arranged in the gun shell, the rotating member is partially located in the adjustment groove, and the rotating member is rotatable to abut against different positions of the adjustment groove, so that the mode adjustment plate limits the mating member to any one of the first position, the second position and the third position;
• wherein the three-mode toy gun has a single-action mode, an automatic mode and a manual mode;
• in the single-action mode, the mating member is located at the first position, the trigger is pressed, the piston member moves towards the tail portion of the gun shell, the push-down bevel can press down the mating bevel, the mating member presses down the convex bar, the first elastic member, the second elastic member, the third elastic member and the fourth elastic member are all in a deformed state, and when the mating member presses down the convex bar to rotate to deflect and disengage from the first switch, the first elastic member and the third elastic member both recover from deformation, and the convex bar is limited at a bottom of the first switch, when the trigger is released, the fourth elastic member recovers from deformation to push against the trigger mechanism away from the first switch, and the second elastic member recovers from deformation to drive the convex bar to rotate to;
• in the automatic mode, the mating member is located at the second position, the inner convex rib is located between the upper convex rib and the lower convex rib, and the inner convex rib runs through the avoidance groove, and in a state where the trigger is pressed, the convex bar keeps abutting against the first switch, and the electric drive mechanism remains in a power-on state, and in a process that the mating member moves from the first position to the second position, the end portion of the inner convex rib slides along the outer convex arc surface and slides into the avoidance groove;
• and
• in the manual mode, the mating member is located at the third position, the second switch is trigged and in an off state, and the electric drive mechanism remains in a power-off state.
