[0006] Furthermore, the front support assembly is provided with a front wheel.

[0007] Furthermore, the rear support assembly is provided with a rear wheel.

[0008] Beneficial effects:

[0009] The front seat plate assembly and the rear seat plate assembly of the utility model are both rotatably connected to the fourth axis, and the rear seat plate assembly is fixed to the rear bracket assembly, which is mainly to maintain the integrity of the backrest assembly without affecting the folding volume of the baby stroller frame. In addition, the front seat plate assembly and the rear seat plate assembly are fixed in relative positions when the frame is opened, which does not affect the user experience.

[0010] The utility model utilizes an ingenious linkage mechanism and its own gravity to enable one-handed operation to open the baby stroller. When the baby stroller needs to be folded, the baby stroller frame can be folded by only releasing the baby stroller frame lock with one hand, and the baby stroller frame can stand on the ground after being folded.
