[0002] Child safety seats are arranged on vehicle seats so that children can be placed in the child safety seat and be better protected, which can effectively improve children's driving safety. A child safety seat's safety belt system usually includes a shoulder belt and a crotch strap arranged between the user's legs. The conventional crotch strap is connected to a buckle at one end and a metal bracket at the other end to connect to the seat body of the child safety seat. The conventional crotch strap has many shortcomings. For example, when the crotch strap is not in use, the crotch strap connected to the buckle often falls to the center of a seat cushion due to the weight of the buckle. Consequently, when a child is to be placed in the child safety seat, the crotch strap and buckle prevent the child from being placed on the child safety seat, so the crotch strap must be removed first.When a caregiver holds the child with both hands, it is often difficult for the caregiver to remove the crotch strap first. In addition, the crotch strap is connected to the seat body via a metal bracket, and the connection structure is complicated and difficult to disassemble, which is inconvenient for cleaning and replacing the crotch strap. Therefore, it is necessary to develop a buckle fastening device with a simple structure and easy detachability that is convenient for caregivers to use.
