A connecting shaft 121 is provided on the surface of the lower housing 12 facing the cable winding cavity. A limiting installation groove 122 is provided on one side of the lower housing 12 where the connecting shaft 121 is located. The cable reel 2 is provided with a torsion spring groove 21, a cable groove 22, and a cable fixing groove 23. The torsion spring groove 21 faces the connecting shaft 121. The torsion spring element 3 is arranged in the torsion spring groove 21. The cable groove 22 is arranged on the outer periphery of the cable reel 2. The cable fixing groove 23 is arranged on the side of the cable reel 2 opposite to the torsion spring groove 21, and one end of the cable fixing groove 23 is communicated with the cable groove 22. A limiting block 24 is arranged outside the torsion spring groove 21 of the cable reel 2. The cable winding limiting assembly 4 is arranged on the limiting installation groove 122 and is used to limit the limiting block 24. Through the ingenious structural design of this embodiment, the efficient storage and stable limitation of the cable of the body fat scale are realized, significantly improving the user experience and the overall performance of the product. The cable winding cavity is formed by buckling the upper housing 11 and the lower housing 12 with each other, which is not only structurally compact, facilitating the overall design and integration of the body fat scale, but also effectively protecting the internal torsion spring element 3 and the cable, and prolonging the service life. The built-in torsion spring element 3 is ingeniously arranged in the torsion spring groove 21. As the cable is pulled out and released, it can automatically complete the winding and stretching of the cable, eliminating the tedious manual arrangement and improving the convenience of use. Through the cooperation of the cable winding limiting assembly 4 on the limiting installation groove 122 and the limiting block 24 on the cable reel 2, the accurate control of the cable winding degree is realized, effectively preventing the problems of excessive cable pulling out or insufficient retraction, and ensuring the neatness and order of the cable. The ingenious design of the cable fixing groove 23 and the cable groove 22 not only ensures the stability of the cable during the winding process, but also facilitates the smooth export of the cable, avoiding the phenomena of cable entanglement or jamming, and improving the smoothness of use. Reducing the disorderly situation of the cable enables the body fat scale to quickly return to a clean state after use.
