TECHNICAL FIELD
[0001] The utility model mainly relates to a kind of child's car bidirectional flip storage joint structure. BACKGROUND
[0002] The adjustment direction of the handlebar on the market is usually fixed, and cannot be adjusted bidirectionally. This is because the original design of the stroller is to facilitate pushing, not to change direction. If you need to change the direction of the stroller, you usually need to turn the entire stroller, not the handlebar. However, for a child's car, the bidirectional flip function of the handlebar is very important to parents, as it allows them to adjust the direction of the handlebar as needed when pushing the child's car, so that parents can face the child while pushing. This not only makes it easier for parents to observe the child's condition, but also allows the child to see the parent, increasing the child's sense of security. In view of this, we have developed a bidirectional flip stroller structure, especially for child's cars, to improve its practicality. SUMMARY
