The winding reel 2 includes a mounting column 21, a lower disk body 22 and a guard arm 23. One end of the mounting column 21 is provided with a connection cavity 211, and the other end is provided with a power connection cavity 212. Such a structural design makes the installation and management of cables easier.

[0028] This embodiment achieves compact and efficient cable management by arranging the lower disk body 22 and the guard arm 23 on the upper and lower sides of the mounting column 21 and forming a winding groove relative to each other.

This design ensures the stability and reliability of the connecting wire and avoids the loosening or falling off of the connecting wire during use. The provision of the tight-fitting buckle 2132 can achieve the fastening and fixation of the connecting wire. By adjusting the position and number of the tight-fitting buckle 2132, the connecting wire can be tightly clamped into the lead groove 213 as needed to ensure the stability and reliability of the connecting wire.

[0034] A through slot 221 is provided on one side of the lower plate 22 facing the guard plate, and a plurality of guard arms 23 are provided, and the plurality of guard arms 23 are arranged continuously along the outer diameter of the mounting column 21. Specifically, a guide strip 231 is provided on one side of the guard arm 23 facing the lower plate 22. In this embodiment, the guard arm 23 is used to guide the cable to be wound, and has good stability during the process of winding and releasing the cable. The guide strip 231 guides the cable toward the winding groove.

[0035] The mounting column 21 is formed with the lower plate 22 and the guard arm 23 by integral injection molding. In this embodiment, an integral structure is formed between the mounting column 21, the lower plate 22 and the guard arm 23 by integral injection molding, thereby achieving a strong connection. The fusion of materials during the injection molding process makes the connection stronger and eliminates the problem of looseness or detachment that may exist in the traditional connection method. The integral injection molding method can combine multiple components into an integral component, reducing the assembly steps in the production process. This can improve production efficiency and reduce production costs.
