The connecting position 71 is a plugging hole for plugging the hand push rod 10. Because the driving medium 7 is rotatably connected with the sliding block 8, after the driving medium 7 slides along the rear supporting frame 3, the driving medium 7 rotates relative to the rear supporting frame 3, so that the connecting position 71 is changed by the rotation of the driving medium 7, the extending direction of the push rod 10 is changed when the baby carrier is unfolded and the extending direction of the push rod 10 is changed when the baby carrier is folded, so that the included angle a between the push rod 10 and the rear supporting frame 3 is smaller than 20 degrees when the baby carrier is folded, the push rod 10 is close to the seat supporting member 6 when the baby carrier is folded, the method that the push rod needs to be disassembled when the traditional baby carrier is folded is changed, and the baby carrier is more compact after being folded. In addition, when the baby carriage in the folded state, the baby carriage in the folded state can be pulled by the push rod 10 to walk, and the baby carriage in the folded state can be towed on the ground, so that the baby carriage is more convenient to carry.
As shown in fig. 6 to 9, the seat support 6 is connected with a backrest 20 which can be unfolded or folded in a rotating manner, and the backrest 20 is connected with a surrounding frame 30 which can be unfolded or folded in a rotating manner. The enclosure 30 ensures the safety of the child sitting and the backrest 20 ensures the comfort of the child sitting. When the buggy is folded, the peripheral frame 30 can be turned onto the backrest 20, then the backrest 20 together with the peripheral frame 30 is turned onto the seat support 6, and finally the push rod 10 approaches the backrest 20.
