A positioning bracket 2 is mounted on one end of the power socket 1 by screws. A guide and protection mechanism is fixed on the positioning bracket 2. The guide and protection mechanism includes a protective cylinder 3, which wraps around and guides the power cord 101. The protective cylinder 3 is fixed to one side of the positioning bracket 2 by screws. Insulating cotton 301 is provided inside the protective cylinder 3 for insulation protection and to guide the power cord 101. The top of the positioning bracket 2 is also fixed with a buckle 4, which stabilizes and limits the power cord 101. A storage box 5 is installed inside the positioning bracket 2. The top of the storage box 5 is provided with a cable inlet 501. The storage box 5 is provided with a cable winding mechanism, which quickly winds up the power cord 101 at the cable inlet 501. It can be extended for use. The cable winding mechanism includes a spring-loaded turntable bearing 6, which is fixed on both sides of the storage box 5. The spring-loaded turntable bearing 6 is a common component that can automatically rotate and retract, making it easy to wind up the entire cable.

[0021] The spring-loaded turntable bearing 6 is equipped with a rotating shaft 601, on which a rotating frame 9 is mounted. The rotating frame 9 has multiple branches, each with a buffer groove. A positioning spring 901 is installed in the buffer groove, and a positioning post 11 is connected to the top of the positioning spring 901. The positioning post 11 slides in the buffer groove, and a positioning plate 10 is provided on the top of the positioning post 11. The positioning plate 10 is arc-shaped and is used to support the power cord 101 to ensure stable winding. One end of the power cord 101 is provided with a plug 401 for connecting to the power supply. The storage box 5 has an outlet on one side, and a quick-clamp mechanism is installed at the outlet. The quick-clamp mechanism can quickly clamp the extended power cord 101 to prevent it from being retracted into the storage box 5 and can be freely adjusted.

[0022] The quick-clamp mechanism includes a clamping frame 7, inside which a rubber pad 701 is installed. The rubber pad 701 is located above the power cord 101. An elastic box 8 is installed at the bottom of the clamping frame 7, inside which a compression spring 802 is installed. An elastic clamp 801 is connected to the top of the compression spring 802. The elastic clamp 801 slides within the clamping frame 7 and is located below the power cord 101. When extension is required, the elastic clamp 801 is pressed down appropriately to pull it out. Once the length is appropriate, the elastic clamp 801 is released for quick positioning. The operation is simple.

[0023] The specific usage and function of this embodiment are as follows: When in use, the power cord 101 with plug 401 is pressed downwards, causing the spring clip 801 to press downwards against the compression spring 802, increasing the gap and facilitating the quick extraction of the power cord 101. Once the appropriate length is reached, the spring clip 801 is released, and the cord is quickly clamped and positioned. The operation is simple. After use, the operation can be repeated. The rotating frame 9 inside the storage box 5 will rotate in the opposite direction as the spring-loaded turntable bearing 6 quickly retracts, thus achieving cord retraction and preventing the power cord 101 from being exposed to the outside for a long time, thereby improving its service life.
