[0002] Suitcases are a common household item. People often carry plastic-framed suitcases when traveling to facilitate the storage and transportation of their luggage. Existing suitcases typically consist of a lid and a body, which can move relative to each other to achieve opening or closing. For aesthetic purposes, edging is usually provided on the edges of both the lid and the body. This edging is usually made of aluminum profiles, which are formed by bending straight aluminum profiles end to end and then connecting them with connecting pieces. The connecting pieces are fixed to the edging with screws. This edging process is complex to manufacture and install, and is also costly and heavy.
