[0037] When the car seat needs to be stored, the locking member 8 is used to release the limit on the back panel 7, and the back panel 7 is rotated toward the side close to the base 1. After the back panel 7 is folded, the locking member 8 is reset, and the limit on the base 1 is released by the lock body 11, and the base 1 is rotated along the rotation center 5. The base 1 drives the back panel 7 to rotate backward, and the rotation center 5 drives the rotating frame 13 to rotate. The rotating frame 13 drives the slider 14 to slide on the rotating frame 13, and the slider 14 drives the connecting rod 15 to move. The connecting rod 15 drives the lock body 11 to rotate along the rotating shaft 10 until the lock body 11 rotates to a preset position and the base 1 is parallel to the car body. At this time, the adjustment of the car seat can be completed.
