When adjusting the position of the data cable 400 by using the positioning group 600, the stud 512 is loosened in advance to release the data cable 400 from the splint 511. After moving the damaged area on the data cable to the interior of the protective cover 520, the stud 512 is tighten to make the stud 512 along with the splint 511 compress the data cable 400, so that the data cable 400 is clamped and fixed inside the fixed sleeve 510.

(24) Referring to FIG. 7, in some embodiments of the present disclosure, the positioning group 600 includes a base fixed on the inner bottom of the protective cover 520, two first rollers 611 and two second rollers 612 are rotatably provided on a top surface of the base 610, and the data cable 400 is wound between the first rollers 611 and the second rollers 612 for transmission. A shaft 620 is rotatably inserted into a middle of a corresponding second roller 612, and a wedge block 621 is fixedly sleeved on an outer side of the shaft 620. The interior of the protective cover 520 is provided with a latch 630 that slides and engages with the wedge block 621, and two telescopic rods 640 is fixed between the latch 630 and the protective cover 520.

(25) In some embodiments of the present disclosure, by manually pulling the pull blocks 622 at both ends of the shaft 620, the data cable 400 is pulled towards the interior of the protective cover 520 through the second rollers 612. This allows the damaged area of the data cable 400 that near the fixed sleeve 510 to be moved to the interior of the protective cover 520 for protection. During the movement of the shaft 620, the wedge block 621 on the outer side of the shaft 620 slides along the latch 630, and the teeth on the latch 630 are also wedge-shaped.

(26) Referring to FIG. 1 and FIG. 2, in some embodiments of the present disclosure, a magnet 121 is fixed on an outer side of the housing base 120, and an iron sheet is fixedly embedded on an outer side of the plug 530. When the data cable is in storage and not in use, the plug component 500 can be magnetically fixed to the magnet 121 for convenient storage of the plug component 500.

(27) Referring to FIG. 3 and FIG. 8, in some embodiments of the present disclosure, a connecting shaft 211 is rotatably connected to a top of the conductive shaft 210, an inner side of the second turntable 320 is fixed with a pillar 322, and two ends of the coil spring 330 are fixedly connected to the connecting shaft 211 and the pillar 33, respectively. In this way, one end of the coil spring 330 is fixed to the connecting shaft 211, and the other end of the coil spring 330 is fixed to the second turntable 320. The connecting shaft 211 is fixed to the second circuit board 130 through the drive column 340. When the second turntable 320 rotates to release the data cable, the second turntable 320 will rotate with the coil spring 330 to collect and store energy. The elastic potential of the coil spring 330 can facilitate the reverse automatic rotation of the second turntable 320 in the later stage to collect the released data cable.

(28) Referring to FIG. 1 and FIG. 8, in some embodiments of the present disclosure, the winding component 300 further includes a drive column 340 fixedly fastened with the connecting shaft 211, and the drive column 340 passes through one end of the second circuit board 130 to slidably connect with a slider 341. The slider 341 is slid to make it inserted into the rectangular slot 131 of the second circuit boar 130, at this time, the connecting shaft 211 cannot rotate on the housing 100, which is beneficial for fixing the middle of the coil spring 330, allowing the coil spring 330 to rotate in the opposite direction after the winding component 300 rotates.

(29) In some embodiments of the present disclosure, a wristband is fixed on the surface of the slider 341 for easy sliding the slider 341. After sliding the slider 341 away from the rectangular slot 131, the drive column 340 can rotate on the second circuit board 130, causing the connecting shaft 211 to no longer be in a fixed state, and the middle of the coil spring 330 to be in an active rotating state. At this time, the winding component 300 rotates to wind up or release the data cable without being affected by the coil spring 330. And the damaged area on the data cable is moved to the interior of the protective cover 520, which will not cause the coil spring 330 to wind up and store energy, and also convenient to release the data cable for long distances. Further, by rotating the drive column 340, longer data cable can also be wound up.

(30) In some embodiments of the present disclosure, the top of the connecting shaft 211 is provided with a notch for easy clamping the coil spring 330, and the bottom of the drive column 340 is fixed with an insert block 342 for clamping with the notch, allowing the drive column 340 to control whether the connecting shaft 211 rotates or not.

(31) Referring to FIG. 9, in some embodiments of the present disclosure, the inner top of the housing base 120 is fixed with a first locating shaft 122 for rotatable installing the swing arm 710, the inner top of the housing base 120 is fixed with a second locating shaft 123 for rotatable installing the rotating wheel 730, and the inner top of the housing base 120 is provided with a mounting groove 124 for receiving a flexure piece 720.

(32) In some other embodiments of the present disclosure, in order to clamp and fix the winding component 300 after releasing the data cable, the following structures are also provided.

(33) Referring to FIG. 3, FIG. 4, and FIG. 6, in some other embodiments of the present disclosure, the clamping component 700 includes a swing arm 710 that is rotatably connected to the inner top of the housing base 120. The outer side of the swing arm 710 is slidably clamped with risen mouldings 710, the outer side of the second turntable 320 is provided with multiple notches 321 that are movable engaged with the rising mouldings 711. The top surface of the swing arm 710 is fixed with the first lug 712 and the second lug 713, the top of the swing arm 710 is fixed with a flexure piece 720, both ends of the flexure piece 720 are in contact with the inner side of the house base 120. The rotating wheel 730 is provided between the first lug 712 and the second lug 713, to rotatably connect with the housing base 120. The outer side of the rotating wheel 730 is provided with the first slots 731 and the second slots 732, with the first slots 731 having a depth greater than the second slots 732.

(34) Specifically, during the process of using the clamping component 700 to retract and release the data cable, when releasing the data cable, the plug component 500 is used to pull the data cable. The data cable rotates with the second turntable 320, causing the risen mouldings 711 on the swing arm 710 to detach from the notches 321 on the second turntable 320. The swing arm 710 deviates from its initial position, and the flexure piece 720 undergoes deformation, providing a reset elastic force to the swing arm 710. After releasing the plug component 500, the elastic force of the coil spring 330 rotates the winding component 300 in the opposite direction to wind up the data cable. However, at this time, the swing arm 710 resets, and the second lug 713 on the swing arm 710 is engaged with the second slots 732 on the rotating wheel 730. Thus the swing arm 710 is limited and fixed, causing the winding component 300 to stop rotating.

(35) When winding up the data cable, one end of the plug component 500 is pulled again, to allow the second turntable 320 rotate again, and the risen mouldings 711 on the swing arm 710 disengages from the notches 321, causing the swing arm 710 to deviate from its initial position. The flexure piece 720 provides the swing arm 710 a restoring force. After the user lets go, the second turntable 320 is reset under the action of the coil spring 330, and at the same time, the flexure piece 720 is reset with the swing arm 710. On the swing arm 710, the first lug 712 is engaged with the first slots 731, and the swing arm 710 is fixed again. Due to the depth of the first slots 731 is greater than that of the second slots 732, when the swing arm 710 is fixed, the angle at which the risen mouldings 711 on the swing arm 710 swings is greater than the angle at which the risen mouldings 711 swings during the data cable being loosen. Additionally, when the risen mouldings 711 stays outside of the notches 321 on the second turntable 320, it cannot prevent the second turntable 320 from rotating, and all data cable are retracted under the action of the coil spring 330.

(36) Referring to FIG. 5, in some other embodiments of the present disclosure, the interior of the swing arm 710 is threadable connected with a screw 714 that being rotatably connecting with the risen mouldings 711. By rotating the screw 714 to make the risen mouldings 711 move away from the second turntable 320, so that the clamping component 700 will no longer control the rotation of the second turntable 320. This makes it convenient for the winding component 300 to release the data cable for long distances, meeting the requirement of pulling out the data cable for long distances in special situations that away from power sockets.

(37) In the present disclosure, the clamping component 700 is the clamping structure disclosed in the Chinese patent CN215732537U titled unidirectional free-pulling data cable, and its detailed operating principle shall not be repeated herein.
