Examples

The working principle of the double-bristle folding brush tool is as follows: before brushing teeth, a user slides the holding upper cover downwards until the holding upper cover is fixed to the fixed position of the holding lower cover, when the brush is used, the second bristle is taken out of the second bristle seat groove, the first brush in a storage state is rotated to a fixed limit position from the holding lower cover, and then the holding upper cover is slid upwards to return to the original position; when the second brush is used, the second brush is held to enable the brush head supporting part of the second brush to rotate to a fixed limiting position from the gap, the second brush seat is fixedly inserted into the brush head supporting part through hole, and then the holding upper cover is upwards slid to return to the original position. After the brush is used, the holding upper cover can slide downwards until the holding upper cover reaches the fixed position of the lower cover, the brush I or the brush II is rotated to be contained in the holding lower cover, the brush II is inserted into the brush seat through hole, and then the holding upper cover slides upwards to the original position. In the using process, if a user needs to look at the cosmetic mirror to determine the tooth brushing condition and effect, the user can look through the cosmetic mirror in the upper cover and hold the lower cover to use the first brush tool or the second brush tool.

Various corresponding changes and modifications can be made by those skilled in the art according to the above technical solutions and concepts, and all such changes and modifications should be included in the protection scope of the present invention.
