Problems solved by technology

[0004] At present, for the traditional buckle, it includes a male buckle, a female buckle and a button. The male buckle and the female buckle are fastened and fixed to each other. The front of the buckle is either located at the back of the male buckle or the female buckle, so that the button is in a very conspicuous position, so that people can quickly find the button, so as to facilitate the pressing operation of the button; however, because the button is in a very conspicuous position Therefore, it is very easy for infants riding in the infant carrier to find the button and touch it subconsciously, thus increasing the risk of accidental release

At the same time, the traditional buckle requires a large force to act on the button when releasing the lock, which increases the difficulty of the unlocking operation

Secondly, the position of the button is set on the front and back surfaces of the male buckle or the female buckle, which increases the chance of scratching with external objects, thereby increasing the risk of accidental release of the lock; of course, there are also buckles with strong concealed buttons on the market, but The structure of the buckle is complicated, and it is inconvenient to release the lock
