[0002] A foundation stick is a container for holding a concealer stick. The concealer stick is usually made in a cylindrical shape and can be directly applied to a person's skin to conceal the skin. The concealer stick is arranged at one end of the tube body, and a telescopic mechanism for controlling the telescopic movement of the concealer stick is arranged in the tube body. When in use, first open the cap, and then control the concealer stick to extend through the telescopic mechanism. After extension, the concealer stick can be applied to a person's skin; after use, the concealer stick is retracted through the telescopic mechanism, and then the cap is covered. The structure and use process of the foundation stick are similar to those of a lipstick.

[0003] For example, CN221356082U discloses a new type of concealer stick, which includes a top cover, a bottom cover, an outer shell, a first sleeve, a second sleeve, and a middle tube. The top cover and the bottom cover respectively cover the openings at both ends of the outer shell. The first sleeve is fixedly arranged in the outer shell. The second sleeve is rotatably arranged on the outer wall of the first sleeve. The middle tube is spirally arranged in the first sleeve. The middle tube is slidably matched with the inner wall of the second sleeve. When the outer shell is rotated, the first sleeve and the second sleeve rotate relative to each other, driving the middle tube to move along the central axis direction of the concealer tube. The inner side of the middle tube has a first thread, and a cosmetic paste body is arranged in the first thread.

[0004] However, when using this kind of concealer stick, it can rotate freely when the outer shell is rotated. Therefore, it is difficult to control the extension amount of the concealer stick. Moreover, there is a certain pressure when the concealer stick is applied. Due to the threaded fit, the outer shell may be turned over, resulting in the retraction of the concealer stick and affecting the use. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the utility model provides a double-headed foundation stick, which can quantitatively extend the concealer stick, has a good operation feel when extending the concealer stick, and will not cause the concealer stick to retract due to a certain pressure during application.
