Description

Technical Field

[0001] This invention relates to the field of power strip technology, specifically to a modular multi-directional splicing power strip. Background Technology

[0002] Power strips, also known as extension cords or power outlets, are electrical devices that expand power interfaces. Retractable power strips are a type of power strip with more flexible and portable design. Their core feature is that the power cord can be stored or stretched through a telescopic structure, solving the problems of tangled and inconvenient storage when the power cord is too long, or limited use when it is too short when the power cord is too short. They are widely used in home, office, and travel scenarios. The most common types are power strips with directly retractable cords and power strips with rotatable plugs.

[0003] However, the aforementioned retractable power strips still have certain drawbacks. For example, power strips that extend and retract directly are prone to deformation and tilting, which can easily lead to poor contact. Rotary plugs have complex structures and are easily damaged. Furthermore, neither type of power strip can freely combine length and direction, resulting in poor expansion flexibility. Summary of the Invention
