ABSTRACT:
A lipstick swivel mechanism includes a cup having a cup body for holding a lipstick bullet; a nosepiece for containing the cup and guiding the movement of the cup; a spiral rotatably connected to the nosepiece, having helical guiding grooves formed on the inner surface thereof; and a screw received within the spiral and detachably connected to the cup. The screw has double helical protrusions, formed on the outer surface of the screw. The double helical protrusions are received in and guided by the helical guiding grooves inside the spiral so as to make the screw and the cup move upward or downward when the spiral is rotated. The problem of idling rotation of screw may be solved.
