Tree topper

An illuminating display device, comprising:

• a rotator,
• a drive,
• a mounting component, and
• a lighting component,
• wherein the rotator and the drive are all mounted to the mounting component, the lighting component comprises a decoration and a light source, the light source is set opposite to the decoration to brighten the decoration, the decoration is fixedly connected to the rotator, the rotator is rotatably connected to the mounting component, and the drive is connected to the rotator to drive the rotator to rotate so as to rotate the decoration;
• wherein the drive comprises a motor and a first gear, the rotator is provided with a second gear, the second gear is fixedly connected to the rotator, and the motor drives the first gear to rotate in order to drive the second gear to rotate so as to drive the rotator to rotate;
• wherein the rotator further comprises a mounting base and a transmission member, the decoration is mounted on the mounting base, the mounting base is fixedly connected to the transmission member, the second gear is fixedly connected to the transmission member, the second gear rotates to drive the transmission member to rotate, the transmission member rotates to drive the mounting base to rotate so as to drive the decoration to rotate;
• wherein the rotation center of the second gear is concentric with the rotation center of the transmission member, and the mounting component further comprises a second fastener corresponding to the rotation center of the second gear and a first bearing set around the periphery of the second fastener, an inner wall of the second gear encloses the second fastener and the first bearing, and the inner wall of the second gear is slidably connected to the first bearing to make the second gear rotatable about the second fastener and thereby make the rotator be rotatably connected to the mounting component.
