It is easier to carry than a stroller and more suitable for traveling with babies.

[0003] In the prior art, it is not easy to tighten the baby waist stool strap quickly. Generally, Velcro is used to fix the waist stool strap, which is unstable. Although the rotating tightening buckle structure can be tightened quickly, the rotating tightening buckle is easy to unlock by itself and has poor reliability. After a caesarean section, the wound on the belly of a woman has not healed completely. Therefore, when the waist stool is not closely attached to the abdomen, the weight of the baby will cause pain in the wound on the woman's belly. Therefore, we have introduced a double rotating tightening buckle for a baby waist stool strap. Utility Model Content
