The winding drum 4, the shell 5, the reserved hole 6, the bracket 7, the circular hole 8, the sliding column 9, the retaining ring 10, the spring 11 and the round block 12 are provided. By pulling the round block 12 to drive the sliding column 9 to slide inside the circular hole 8, the sliding column 9 will drive the retaining ring 10 to squeeze the spring 11 toward the position of the bracket 7 during the sliding process. After squeezing a certain distance, the sliding column 9 will move away from the limiting hole 15, and then rotate the rotating plate 13 after moving away, and drive the winding drum 4 to rotate inside the shell 5 through the rotating plate 13. During the rotation of the winding drum 4, the wire harness body 1 will be retracted from the reserved hole 6 into the inside of the shell 5, and then be reeled on the winding drum 4. After the reeling is completed, the round block 12 is released, and then the rebound force of the spring 11 will bounce the sliding column 9 into the limiting hole 15. This structure can store the wire harness body 1, thereby effectively preventing the wire harness body 1 from being easily knotted and entangled during storage or carrying, which is convenient for users.

[0024] See also Figure 1 and Figure 3-4 The limiting hole 15 is slidingly connected to the sliding column 9, and the limiting effect of the winding drum 4 is improved through the sliding connection.

At the same time, the anti-skid effect when rotating the rotating plate 13 is improved by the anti-skid strips 14, which effectively avoids slipping when rotating the rotating plate 13.

[0027] Working principle: when the wiring harness body 1 needs to be stored, first pull the round block 12, and drive the slide post 9 to slide inside the round hole 8 through the round block 12. During the sliding process, the slide post 9 will drive the retaining ring 10 to squeeze the spring 11 toward the bracket 7. After being squeezed for a certain distance, the slide post 9 will move away from the limiting hole 15, and then rotate the rotating plate 13. After moving away, the winding disk 4 is driven to rotate inside the shell 5 through the rotating plate 13. During the rotation process, the winding disk 4 will retract the wiring harness body 1 from the reserved hole 6 into the inside of the shell 5, and then reel it on the winding disk 4. After the winding is completed, release the round block 12, and then the rebound force of the spring 11 will bounce the slide post 9 into the limiting hole 15, thereby limiting the winding disk 4.
