Specifically, the rotation post 322 is inserted in the rotation groove 114 and can rotate in the rotation groove 114, and the rotation post 322 is disposed in parallel with the connecting shaft 14 at intervals. Through the rotating cooperation between the rotation post 322 and the rotation groove 114, the rotatable connection between the brush head 10 and the moving sleeve 30 is realized, which has a simple structure and is convenient to manufacture.

In another embodiment of the present disclosure, the inner wall of the moving sleeve 30 of the provided cosmetic tool is provided with a rotation groove 114, and the peripheral wall of the brush head 10 is provided with a rotation post 322 which is rotatably connected in the rotation groove 114. Specifically, the rotation post 322 is inserted in the rotation groove 114 and can rotate in the rotation groove 114, and the rotation post 322 is disposed in parallel with the connecting shaft 14 and at intervals along the axial direction of the moving sleeve 30. Through the rotating cooperation between the rotation post 322 and the rotation groove 114, the rotatable connection between the brush head 10 and the moving sleeve 30 is realized, which has a simple structure and is convenient to manufacture.

In another embodiment of the present disclosure, as shown in FIGS. 9, 10 and 15, the rotation groove 114 of the provided cosmetic tool is an elongated groove.

Specifically, the linear hole 323 can be located between the semicircular hole 321 and the material core 20, or at the side of the semicircular hole 321 facing away from the material core 20. When the linear hole 323 is located between the semicircular hole 321 and the material core 20, and the moving sleeve 30 moves until the brush head 10 is turned over by 180° and dips in the cosmetic material, because the rotation post 322 can continue to move along the rotation groove 114 while the connecting shaft 14 can also continue to move along the linear hole 323, the moving sleeve 30 can continue to move along the axial direction, and thus the brush head 10 is driven to continually move towards the discharge port of the material core 20. Therefore, the amount of the cosmetic substance dipped with the brush head 10 can be adjusted by controlling the moving distance of the moving sleeve 30. When the moving sleeve 30 continues to move for a large distance, the pressing force by which the brush head 10 is tightly pressed at the discharge port is large, and more cosmetic substance is dipped by the brush head 10; and when the moving sleeve 30 continues to move for a short distance, the pressing force by which the brush head 10 is tightly pressed at the discharge port is small, and less cosmetic substance is dipped by the brush head 10. When the linear hole 323 is located at the side of the semicircular hole 321 facing away from the material core 20, and after the brush head 10 turns over reversely by 180° as driven by the moving sleeve 30 so that the brush head 10 is exposed outside the moving sleeve 30, since the rotation post 322 can continue to move along the rotation groove 114 while the connecting shaft 14 can also continue to move along the linear hole 323, the moving sleeve 30 can continue to move along the axial direction, so as to drive the brush head 10 to continually move towards the outside of the moving sleeve 30, so that the exposed part of the dipping member 13 of the brush head 10 can be gradually increased, thereby facilitating the brushing of the cosmetic substance. Meanwhile, during the brushing process of the cosmetic substance, components such as the moving sleeve 30 and the fixed sleeve 40 will not rub against the skin, thereby improving the brushing comfort of the cosmetic substance. After the rotation post 322 enters the rotation groove 114 and the connecting shaft 14 also enters the linear hole 323, the brush head 10 will not turn over when the cosmetic substance is brushed, which makes the operation of brushing the cosmetic substance simpler and easier.

Specifically, the moving sleeve body 31 serves as a mounting base of the material core 20, and the moving arm 32 serves as a mounting base of the brush head 10. At the same time, a gap formed between the two moving arms 32 can provide a turnover space for the brush head 10 to turn over, so that the turnover of the brush head 10 is smoother and more reliable. Additionally, the two ends of the connecting shaft 14 are respectively connected by penetrating the semicircular holes 321 of the two moving arms 32, so that the reliability of the connection between the brush head 10 and the moving sleeve 30 is good, and the reliability and stability of the turnover of the brush head 10 are better.
