[0031] Working principle: When in use, the utility model electrically connects the driving servo 2 to the external control power supply. When the driving servo 2 is electrically connected to the external control power supply, the driving servo 2 is controlled to rotate. When the driving servo 2 rotates, it drives the transmission single half gear 3 to rotate. When the transmission single half gear 3 rotates, it meshes and drives the first transmission full gear 4 to rotate. When the first transmission full gear 4 rotates, it drives the main transmission shaft column 5 to rotate.
