Description

Technical Field

[0001] This utility model relates to the field of mobile phone accessories technology, specifically a mobile phone lanyard clip and its phone case. Background Technology

[0002] Chinese utility model patent CN202321682607.3 discloses a mobile phone lanyard, which includes a flexible connector and a lanyard assembly. The flexible connector includes a fixing card and a connecting card. The connecting card is fixed to or integrally formed with the lower end of the fixing card. A connecting hole is formed in the middle of the connecting card. A connecting buckle is provided at each end of the lanyard assembly, and the two connecting buckles are respectively fastened in the connecting hole. The above-mentioned mobile phone lanyard clamps the flexible connector between the protective case and the mobile phone. The connecting card extends from the charging port and connects to the lanyard assembly. In addition, the flexible connector increases the friction between the protective case and the mobile phone through an anti-slip layer, and is attached to the mobile phone and / or protective case through an adhesive layer. At the same time, the flexible connector and the lanyard assembly are connected by the connecting buckles. The aforementioned connector is a straight plate. While flexible, it requires bending to pass through the charging port of the protective case. Inadequate bending can lift the phone, affecting its assembly stability. Furthermore, prolonged use can lead to severe deformation or even breakage, causing the phone to fall and damage. The deformed connector can also obstruct the charging port, affecting data cable insertion and removal. Additionally, the connector can only be used for the charging port; it cannot be used for attaching decorative ornaments or straps to other parts of the case (such as the sides or top), resulting in low flexibility and versatility, negatively impacting the user experience. Therefore, further improvement is necessary. Utility Model Content

[0003] The present invention aims to provide a mobile phone lanyard clip and a mobile phone case thereof to overcome the shortcomings of the prior art.

[0004] A mobile phone lanyard clip designed for this purpose includes a connecting piece, which is a flat sheet with a bent portion. The bent portion is composed of an inclined extension edge, a planar extension edge, a right-angle extension edge, and a connecting hole connected in sequence.
