[0002] Child safety seats are the safety guarantee for infants or children in cars, but for children of different ages, the direction of placement of safety seats is different. For example, before the age of 1, the safety seat must be seated in reverse, and then it can be fixed forward; In order to save unnecessary expenses for consumers, the current manufacturers design the safety seat to be universal. For example, from the age of 0 to the age of 3 to 5, only one child safety seat can be purchased. The safety seat is placed behind the vehicle. The seat needs to be connected to the ISOFIX interface of the vehicle through the ISOFIX device. There are two ways to place the universal child safety seat. In order to solve the connection problem of the ISOFIX device, the usual practice is to set the ISOFIX device as a front and rear rotatable structure. This will reduce the strength of the connection between the ISOFIX device and the child safety seat bracket, and the bottom of this convenient child safety seat needs to be slotted, and it is not convenient to turn over
