[0002] The backpack buckle is a widely used connector. The backpack can be carried on the back or tied around the waist through the backpack strap. The backpack buckle can adjust the length of the backpack strap and connect two backpack straps. The backpack buckle is composed of two fasteners that are plugged into each other. Each fastener is connected to the backpack strap. When in use, the fastener with a pin is inserted into another fastener with a buckle part, and the pin is stuck in the buckle part to achieve connection; when disassembling, pinch the pin to separate the two fasteners. In addition to the basic performance requirements such as structural strength and materials, the fatigue durability of insertion and opening is also one of the important indicators to measure the performance of the backpack.
