The first connection interface and the second connection interface are connected by a data line, and the data line is retractably wound around the winding structure.

As shown in FIG. 1 to FIG. 3, in this embodiment, the first connection interface is a USB interface, and the second connection interface is a mobile device interface. The mobile device communicates with the computer or host by connecting to a computer or other form of host via a USB interface while connecting the mobile device to the mobile device interface. And the mobile device can be powered and charged via the USB interface.

In the present embodiment, the USB interface includes a USB plug 11, a USB cover 12 provided outside the USB plug 11, and a cover button 13. The USB plug 11 includes a plug, a baffle, a cover, and the like, and has the same structure as the conventional USB plug 11, and therefore will not be described again. A support shaft 131 is disposed inwardly on both sides of the cover button 13, and is rotatably mounted on the outer casing, and a hook 132 is disposed on both sides thereof. Fasten the USB cover 12. The two sides of the USB cover 12 are provided with a button hole that cooperates with the hook 132. Therefore, the USB cover 12 is fastened to the cover button 13 by the cooperation of the hook 132 and the buckle hole, and the USB plug 11 is covered to prevent dust and damage. When the USB plug 11 is required to be used, the hook 132 of the cover button 13 is pressed, and the snap-fit state of the button cover of the USB cover 12 is released, so that the USB cover 12 can be removed and the USB plug 11 can be used. In order to increase the rigidity and the elastic restoring force between the hooks 132, a spring 133 is provided between the support shafts 131 of the hooks 132 on both sides to provide support and elastic restoring force. The end of the cover button 13 can also be provided with a barb 134 for fastening to the outer casing.

In this embodiment, the mobile device interface is a mobile phone interface 14, which includes a mobile phone plug 141 and a plug shutter 142. The handset plug 14,1 is mounted to one side of the housing via the plug shutter 142, and the handset plug 141 and the USB plug 11 are connected for communication via the data line 15. Thereby, the mobile phone is connected to a computer or other host through the mobile phone plug 141 and the USB plug 11, and the mobile phone can be charged by the USB plug 11 to charge the battery of the mobile phone.

The housing includes a face-to-face case 16 and a lower cover 17, and the handset interface 14 and the USB interface are disposed on opposite sides of the housing, respectively. A support shaft 171 is provided at an intermediate position of the lower cover 17 as a central axis of the winding structure. The intermediate position of the support shaft 171 is provided with a slit 172 for fixing the center end of the torsion spring piece 19.

The winding structure includes a bobbin 18 rotatably mounted within the outer casing, and a torsion spring 19 mounted on the bobbin 18. In the present embodiment, the bobbin 18 is mounted on the support shaft 171 of the lower cover 17, so that the bobbin 18 is rotatable about the support shaft 171. One end of the bobbin 18 is provided with a wire slot 181 for clamping the data line 15 so that the data line 15 is fixedly wound around the bobbin 18. The other end of the bobbin 18 is provided with a receiving groove 182 for receiving the torsion spring piece 19. A limiting protrusion 183 is protruded inwardly from a side wall of the accommodating groove 182 for fixing the end of the torsion spring piece 19, since both ends of the torsion spring piece 19 are relatively fixed, so that the torsion spring piece 19 does not follow the winding axis 18 rotation, when the bobbin 18 is rotated, To the effect of accumulating potential energy, an elastic restoring force is provided to drive the bobbin 18 to tighten the data line 15.

The winding structure is further provided with a limiting mechanism, which comprises a limiting block 20, a sliding cover 21, a slider 22, a slider 23 and a spring 24. The side wall of the limiting block 20 is provided with a card slot 201, and is inserted into the limiting protrusion 183 of the receiving groove 182 so as to be fixedly connected with the winding shaft 18 and rotate together with the winding shaft 18. The slider 21 is disposed outside the casing to provide the user with the possibility of unlocking operation. The slider 22 is mounted on the inner side of the face shell 16 and is slid by the slide cover 21. The spring 24 is connected to the slider 22 to bring the slider 22 to reset.

The ratchet groove 202 cooperates with the slider 22 to limit the rotation of the winding shaft 18. When the slider 21 is pushed, the slider 22 is driven out of the ratchet groove 202, thereby releasing the limit of the limiting block 20, so that the winding shaft 18 can be rotated by the torsion spring 19 to retighten the data line 15. When the slide cover 21 is released, the slider 22 is again engaged with the ratchet groove 202 by the spring 24, and the rotation of the stopper 20 is again restricted, that is, the rotation of the spool 18 is restricted.

The action process is: when the handset interface 14 and the USB interface are pulled outward, the data line 15 drives the bobbin 18 to rotate in one direction (for example, clockwise direction), compresses the torsion spring 19, and is prevented by the limiting block 20. The bobbin 18 is rotated in the reverse direction so that the torsion spring 19 stores potential energy. When the sliding cover 21 is pushed to release the limiting action of the limiting block 20, the torsion spring 19 is elastically restored, and the winding shaft 18 is driven to rotate in the opposite direction (for example, counterclockwise), thereby tightening the data line 15, and the mobile phone interface 14 is And the USB interface is retracted into the housing.

A circuit board is also mounted in the housing, and the data line 15 is electrically connected to the circuit board. The circuit board includes an incoming call sensing circuit, so that when the mobile phone calls, an indication can be sent through the incoming call sensing circuit, and the LED mounted on the outer casing flashes to indicate an incoming call.

The circuit board is provided with a laser emitting circuit for generating laser light and emitting the outer casing, and can emit laser light to function as a laser pen. A battery is disposed on the circuit board, and the battery provides power through the second connection interface via the data line 15. Therefore, the portable data switching device for mobile phones of the present invention can provide backup power for terminal devices such as mobile phones, and expands its application.
