Quadcopter toy

A quadcopter toy, comprising a fuselage main body;

• and four rotor units arranged around the fuselage main body, wherein each rotor unit comprises a rotor, a rotor motor for driving the rotor to rotate, and a rotating shaft of the rotor is vertical;
• the quadcopter toy further comprises a circular decorative ring, wherein the circular decorative ring is fixedly connected to a horizontal rotating shaft;
• the horizontal rotating shaft passes through the fuselage main body, and an extension direction of the horizontal rotating shaft is a diameter direction of the circular decorative ring;
• a main motor and a transmission mechanism which drive the horizontal rotating shaft to rotate are also arranged inside the fuselage main body;
• the fuselage main body and the four rotor units are located inside a spherical space surrounded by a rotation trajectory of the circular decorative ring;
• the transmission mechanism comprises several transmission gears;
• two locating pieces are arranged at an eccentric position of one of the transmission gears;
• distances from the two locating pieces to a center point of the transmission gear are the same;
• a pawl that cooperates with the two locating pieces is mounted in the fuselage main body;
• the pawl does not block clockwise rotation of the locating pieces around a central axis of the transmission gear, but blocks anticlockwise rotation of the locating pieces around the central axis of the transmission gear;
• when a first locating piece rotates anticlockwise around the central axis of the transmission gear until the first locating piece is in contact with a tail end of the pawl and stops, a plane where a center line of the circular decorative ring is located is parallel to an extension direction of the rotating shaft of the rotor;
• and when a second locating pin rotates anticlockwise around the central axis of the transmission gear until the second locating pin is in contact with the tail end of the pawl and stops, the plane where the center line of the circular decorative ring is located is perpendicular to the extension direction of the rotating shaft of the rotor.
