1. A rotating mechanism adapted to be used with a high-penetration atomizing beauty instrument, comprising an air-liquid tube shaft, a joint and a liquid suction tube, wherein
a slot is provided at a middle position of the air-liquid tube shaft, and a length direction of the slot is perpendicular to an axial direction of the air-liquid tube shaft;
a linear through hole is provided at a bottom of the joint and the air-liquid tube shaft penetrates the linear through hole at the bottom of the joint, and the air-liquid tube shaft and the joint are rotatable with each other; and
the liquid suction tube is fixed in an inner hole of the joint, and one end of the liquid suction tube is inserted into the slot, and movable within 90° along a circumferential direction of the air-liquid tube shaft;
a length of an outer surface of the slot is a sum of a quarter of a circumference of the air-liquid tube shaft and an outer diameter of the liquid suction tube; and
a maximum rotation angle between the joint and the air-liquid tube shaft is restricted to 90°.
