[0013] 1. During use, the staff first inserts the connecting rod into the steering positioning tube until the clamping block is engaged with the concave arc groove. Since the first anti-slip ring and the second anti-slip ring are semicircular ring structures of the same diameter and height, and the first anti-slip ring fits the top surface of the clamping block, the first anti-slip ring can be directly buckled with the second anti-slip ring. At this time, the first fixing hole is connected to the first threaded groove, and the staff can pass the first bolt through the first fixing hole and connect it with the internal thread of the first threaded groove, thereby fixing the connecting rod to the steering positioning tube. When the baby carriage is subject to vibration, impact or other external forces during driving, the clamping block will not shake up and down in the concave arc groove due to the resistance of the first anti-slip ring and the second anti-slip ring on the top, and the connecting rod will not fall off from the steering positioning tube, thereby improving the safety and reliability of the baby carriage;

[0014] 2. During use, since the angle of the slide groove inside the fixed ring is degrees, the slider can rotate degrees to the left or right in the slide groove. When driving the baby stroller, the child can turn the handle to the left or right at an angle of degrees, which improves the maneuverability of the baby stroller. The dynamic stability of the vehicle will not decrease due to the excessive steering angle of the baby stroller, which will cause the baby stroller to lose control, thereby ensuring the safety of children. The mounting plate fixed on the outer wall of the sleeve can be fixed to the internal bracket of the baby stroller, so that the entire device is fixed inside the baby stroller. A steering paddle is fixed at the bottom of the steering positioning tube. The steering paddle is perpendicular to the steering positioning tube, and the position of the steering paddle corresponds to the position of the handle. Two symmetrical connecting holes are arranged on the outer side of the steering paddle. The two connecting holes are rotatably connected to the steering connecting rods on the left and right wheels respectively, which improves the applicability of the device.
