[0002] Baby strollers are mainly used to carry babies for outdoor walking. When transporting and storing, the baby stroller needs to be folded to reduce the size for storage. To achieve this purpose, baby strollers have various folding structure designs. The folding and unfolding process requires both hands to operate, which is complicated to operate. In addition, there are shortcomings such as poor stability and insufficient strength at the joints when unfolding. Some of the existing folding components are set at the joint unit. The joint units on both sides need to be folded synchronously before the frame body can be folded. It is impossible to complete the folding quickly and it is impossible to provide convenience for users to fold and open the stroller. Utility Model Content
