When the third locking member 5 is connected to and locked with the anchoring mechanism, the third locking member 5 rotates relative to the telescopic member 2, the sliding assembly 61 is pulled to slide backward under the action of the tension spring 64, so that the sixth matching portion 61b is gradually clamped into the fifth matching portion 51, when the sliding assembly 61 slides backward, the first locking member 31 is driven to slide backward synchronously, the rear end face, namely the inclined face, of the first limiting portion 311 is abutted against the first slot 21, and when the sliding assembly 61 continuously slides backward, the first locking member 31 rotates around the rotation connection position of the first locking member 31 and the sliding assembly 61 through the interaction between the inclined face and the first slot 21 until the first limiting portion 311 is separated from the first locking slot 11, the first locking mechanism is unlocked, and in the process, the third locking member 5 is connected to and locked with the anchoring mechanism, and the second locking mechanism is still in a locking state, as shown in fig. 3. In this state, the fixing member 1 can be slid rearward relative to the telescoping member 2, bringing the fixing member 1 and telescoping member 2 together, and bringing the seat closer to the backrest of the car seat, as shown in fig. 4.
When the child car seat needs to be detached from the car seat, a user holds the operating member 62 and the rotating shaft 7 at the same time, and applies force to the operating member 62, so that the operating member 62 slides forward in a direction approaching to the rotating shaft 7 relative to the rotating shaft 7, and when the operating member 62 slides forward, the sliding assembly 61 can be driven to slide forward synchronously, and after the third locking member 5 is pulled by the tension spring 64 to rotate reversely by a certain angle relative to the telescopic member 2, the connection between the third locking member 5 and the anchoring mechanism is released, and the sixth matching portion 61b is far away from the fifth matching portion 51, as shown in fig. 5.

In this embodiment, during the unlocking process, the first locking member 31 and the second locking member 41 simultaneously start to rotate relative to the telescopic member 2 and simultaneously disengage from the first locking groove 11 and the second locking groove 12, i.e. the first locking mechanism and the second locking mechanism simultaneously start to unlock and simultaneously complete unlocking. In this state, the fixing member 1 and the telescopic member 2 can be freely slid relatively forward or backward to adjust the relative position therebetween.
The front-rear direction is defined by the front-rear direction of the car after the child car seat is connected to the car seat.
