Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

As shown in fig. 1 and 6, the middle bundle core of the present invention comprises a middle bundle 1, a spiral 2, beads 3 and forks 4, wherein the middle bundle 1 is sleeved on the periphery of the spiral 2 and is tightly connected with the spiral 2. Spiral 2 top-down cover in 4 peripheries of fork for spiral 2 and 4 axial fixings of fork, fork 4 includes pole body part 44 and

base

45, 45 protrusion in 2 bottoms of spiral of base of fork 4, be equipped with spout 41 on the fork 4, 2 inner walls of spiral are equipped with spiral guide way 22, be equipped with protruding 31 on pearl 3, pearl 3 is installed in fork 4, and protruding 31 on the pearl 3 passes spout 41 on the fork 4, make pearl 3 and fork 4 radially fixed, the protruding 31 joint of pearl 3 is in spiral guide way 22 on 2 inner walls of spiral simultaneously. Therefore, when the fork 4 and the screw 2 move relatively, the spiral guide groove 22 and the protrusion 31 of the bead 3 generate friction force and the sliding groove 41 limits the protrusion 31 of the bead 3, so that the bead 3 moves up and down, and lipstick or lipstick is contained in the bead 3 and can move up and down along with the bead 3. In order to ensure the friction force between the screw 2 and the fork 4, the fork 4 is provided with a protrusion 42 on the circumferential surface, and the protrusion 42 is in an annular structure, correspondingly, the bottom of the screw 2 extends downwards along the inner wall to form an annular sheet-shaped contact layer 23, and the inner wall of the contact layer 23 abuts against the outer edge of the protrusion 42. It should be noted here that although the protruding portion 42 is provided with only one turn in fig. 5 to 7, the practical technical solution is not limited to this, and a plurality of turns of the protruding portion 42 may be provided.
