It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 4, a cosmetic middle bundle core comprises a middle bundle 1, an inner cylinder 2, beads 3 and forks 4, wherein the inner cylinder 2 is formed by curling a metal sheet, a spiral groove 21 is formed on the peripheral wall of the inner cylinder 2 by adopting a stamping process, the inner cylinder 2 is supported in the middle bundle 1, the forks 4 are sleeved in the inner cylinder 2, a slot 41 is formed on the peripheral wall of the fork 4, the beads 3 are installed in the forks 4, and protrusions 31 on the outer wall of the beads 3 protrude out of the slot 41 and are matched with the thread groove 21. Specifically, in this embodiment, the middle bundle 1, the inner barrel 2, the beads 3 and the fork 4 are all made of aluminum, so that the appearance is attractive and elegant, the service life is long, the hand feeling is excellent, and the user experience is good. Meanwhile, it can be understood that the process is the existing mature stamping process after the inner cylinder 2 cut into the square sheet shape is stamped with the spiral groove 21 on the surface, and the process is not described herein again.
