The spring 7 structure is used as a power source and can provide a driving force for the rotating shaft 8 to rotate the rotating shaft 8. After the rotating shaft 8 rotates, the rotating wheel 9 on the rotating shaft 8 can be driven to rotate, so that the data line 2 on the rotating wheel 9 is tightened along the rotating wheel 9.

It should be noted that, when the user needs to pull out the OTG-USB plug 3, in the process of pulling out the OTG-USB plug 3, the data line 2 drives the rotating wheel 9 to rotate in the opposite direction, and the rotating wheel 9 drives the rotating shaft 8 to rotate, so that the clockwork spring 7 on the rotating shaft 8 is tightened, and the clockwork spring 7 stores power.

Referring to fig. 5 and 6, in some embodiments of the present invention, the rotating shaft 8 is provided with a rotating structure, the rotating structure includes a rotating head 11 and an annular housing 10 fixed in an axial direction of the rotating shaft 8, the rotating head 11 is disposed in the annular housing 10, the rotating head 11 is electrically connected to the annular housing 10, the rotating head 11 can rotate along the annular housing 10, the data line 2 is connected to the rotating head 11, the annular housing 10 is provided with a connector 12, and the connector 12 is connected to a connector 12 on another rotating shaft 8.

The working principle of the spring 7 is the lever moment principle. When spring 7 is full, its moment is the largest (moment lever is the longest) so the front end of spring 7 needs to be output with less force. After a certain period of operation, spring 7, wound tightly around the shaft of spring 7, is slowly unwound, with a consequent reduction in its energy. When the energy is about to be exhausted, the moment at the tail end of the spring 7 is minimum (the moment lever is shortest), and the output force is reduced accordingly. In the process of moment quantitative change, the travel time precision of the movement is completely the average value of the front and the back. When the OTG-USB plug 3 is pulled out, the data line 2 drives the rotating wheel 9 to rotate, so that the rotating shaft 8 on the rotating wheel 9 rotates. At this time, the rotation of the rotating shaft 8 can make the clockwork spring 7 tighten (fill up the clockwork spring 7), and the rotation energy is converted into potential energy to be stored in the clockwork spring 7. When the data cable is not used, the data cable 2 is loosened, the clockwork spring 7 converts potential energy into rotational energy, the rotating shaft is rotated, and the rotating wheel 9 on the rotating shaft rotates to withdraw the pulled data cable 2.

The groove 4 is used as a space for accommodating the OTG-USB plug 3, and when the OTG-USB plug is not used, the OTG-USB plug 3 can be accommodated in the box body 1, so that the box body 1 is convenient to carry. Meanwhile, the OTG-USB plug 3 is high in precision and easy to damage, and particularly, the OTG-USB plug 3 can be abraded in the carrying process of a user. Therefore, the OTG-USB plug 3 in the groove 4 can be protected, and the OTG-USB plug 3 can be prevented from being damaged by external force or foreign objects.

Referring to fig. 4, in the embodiment, a position-limiting plate for blocking the OTG-USB plug 3 is disposed in the groove 4, a through hole is formed on the position-limiting plate, and the data line 2 passes through the through hole to be connected to the OTG-USB plug 3. The second cavity 6 can be isolated from the groove 4 by the limiting plate, and the OTG-USB plug 3 is prevented from entering the second cavity 6. Meanwhile, the through holes in the limiting plates operate the data lines 2 to enter and exit, so that the movement of the data lines 2 is not influenced.

It should be noted that the through hole has a relatively smooth structure, and the through hole is rounded, so that the movement of the data line 2 is hardly affected by the friction of the through hole. This kind of structure can prevent that data line 2 from receiving the frictional force influence at the through-hole for a long time, appearing wearing and tearing scheduling problem.
