This positioning method not only simplifies the assembly process and improves production efficiency, but also effectively avoids assembly errors caused by inaccurate positioning. Furthermore, the use of fixing clips 211 prevents the wiring rotating plate 41 from loosening or falling off when subjected to external forces, thereby ensuring the proper operation and long life of the body fat scale cable reel. Furthermore, the design of the fixing clips 211 facilitates subsequent maintenance and replacement, reducing the maintenance cost of the body fat scale cable reel.

[0031] The wiring connector 42 is provided with a fixing member 422, which is provided with multiple fixing slots 423. The conductive contact spring 421 is positioned in the fixing slots 423. The fixing slots 423 are used to secure the end of the conductive contact spring 421 to the wiring rotating plate 41. In this embodiment, the fixing member 422 serves as a core component, not only ensuring the stable installation of the conductive contact spring 421, but also, through the multiple fixing slots 423 therein, achieving precise positioning and secure fixation of the end of the conductive contact spring 421. This design effectively prevents the conductive contact spring 421 from loosening or shifting on the wiring rotating plate 41, thereby ensuring the electrical connection stability and signal transmission reliability of the body fat scale cable reel during use.

[0032] The plurality of conductive contact rings 431 are coaxially arranged. In this embodiment, the number of conductive contact rings 431 is increased, so that the distribution of current during transmission is more uniform, effectively reducing energy loss and resistance, and making the measurement result of the body fat scale more accurate and stable. Secondly, the structure of the coaxial arrangement of the plurality of conductive contact rings 431 also has good self-adaptive adjustment function. When the body fat scale is affected by the external environment during use, such as vibration, impact, etc., the elastic contact between the conductive contact rings 431 can automatically adjust to maintain stable electrical connection, thereby ensuring the measurement accuracy and stability of the body fat scale.
