[0002] During the bathing process of infants and young children, safety and convenience are the most important considerations. Traditionally, parents or caregivers usually bathe infants and young children by holding them, or place infants and young children in a bathtub with anti-slip design for bathing. To further improve the safety and comfort of bathing infants and young children, some special bathing brackets for infants and young children have emerged on the market. These brackets are usually designed with a certain inclination angle and supporting function to fix the body of infants and young children, so as to reduce accidents caused by the continuous movement of infants and young children during bathing.

[0003] In the Chinese design patent with the publication number CN307363223S and the patent name "Children's Standing Bathing Rack (LBN - 6268)", a standing bathing bracket suitable for infants and young children is disclosed, which has two arm protectors for holding infants and young children under their armpits. However, the arm protectors of this product are fixed and cannot be adjusted according to the chest circumference of infants and young children.

[0004] In the Chinese design patent with the publication number CN306537938S and the patent name "Baby Standing Helper", movable arm protectors are disclosed. An activity gap between the arm protectors and the main body can be clearly seen in the patent drawings. However, the arm protectors of this product are usually always movable and will loosen due to the shaking of infants and young children during bathing. Summary of the Invention
