BACKGROUND
According to the current baby strollers having retractable handles in the prior art, a handle is used to fold a baby stroller and open the folded structure of the stroller frame during the movement of the handle within a handle holder, which is in part to control a locking head by means of a pull wire and set the relative distance between the handle and the handle holder, so as to achieve a folded state and an open state of the stroller frame. This method of controlling the locking head by means of a pull wire, when implemented, has a complex structure and inconvenient operation. The pull wire needs to be provided within the space where a first handle and a second handle move with respect to each other or be exposed to the outside, so as to avoid the movement track of the elements without being affected. At the same time, the locking head on the pull wire needs to be controlled by a left pull handle and a right pull handle, and thus single-handed operation is not possible, and it is necessary to operate the pull handles with both hands so as to achieve the purpose of folding the stroller. Therefore, the current strollers have a complex structure and inconvenient operation.
Accordingly, it is very necessary to design an unlocking structure for folding a baby stroller having a simple structure and convenient operation, so as to control the retractable height adjustment of a handle by means of single-banded operation and achieve the purpose of folding the stroller with a single hand by striking the stroller.
