Rotary lamp holder structure

According to the rotating lamp holder structure, the rotating axis of a rotating wheel is transversely arranged, and all light-emitting units are sequentially arranged in the circumferential direction of the rotating wheel; the first multi-layer gear comprises a first gear and a second gear which are distributed in the front-back direction, the second multi-layer gear comprises a third gear and a fourth gear which are distributed in the front-back direction, the first gear is in meshed connection with the driving gear, the second gear is in meshed connection with the third gear, and the fourth gear is a first bevel gear; the first bevel gear is in meshed connection with the second bevel gear; the driving gear is used for driving the first multi-layer gear to rotate, the first multi-layer gear rotates to drive the second multi-layer gear to rotate through meshing connection of the second gear and the third gear, and the second multi-layer gear rotates to drive the rotating wheel to rotate through meshing conne
