The using method and the principle of the telescopic data line are as follows:

in the first embodiment, when the telescopic data line is used, the two plugs are respectively pulled to two sides, and the clamping mechanism can be used as a gear mechanism for stretching the length and can adjust the length of the wire extending out of the shell according to the requirement; while the wire is stretched, the elastic element is gradually unfolded along with the rotation of the turntable. When the wire is taken up, the contraction elastic force of the elastic elements in the two turntables can drive the two turntables to rotate reversely, so that the wire is taken back and wound on the turntables.

In the second embodiment, when the retractable data cable is used, the wire is stretched in the same manner as in the first embodiment. Because the two turntables can be meshed and linked in the second embodiment, the telescopic data wire can be tightened only by resetting the elastic element on one of the turntables when the telescopic data wire is taken up. If the elastic elements are respectively arranged between the two turntables and the shell, the winding of the wire rod can be more rapid and powerful.

In addition, the diameter of the winding part on the lower surface of the turntable is smaller than that on the upper surface of the turntable. If the wire winding directions of the wire on the upper surface and the wire on the lower surface of the turntable are the same, when the wire is stretched and paid off, the wires on the upper surface and the lower surface of the turntable are paid off (the wire on the upper surface is paid off from the shell, and the wire on the lower surface is still in the shell after the wire is paid off), and when the coil spring is reset and taken up, the wires on the upper surface and the lower surface of the turntable are tightened (the wire on the upper surface is taken up into the shell, and the wire on the.

If carousel upper surface wire rod and lower surface wire rod wire winding opposite direction, the lower surface wire rod need leave the surplus when the wire winding, has great clearance between the wire rod each layer promptly, for rotating winding wire rod reservation space to when preventing that the carousel from rotating, the wire rod tightens up the limit very fast, and leads to the card to die, unable rotation. When the coil spring is reset to take up, the wire on the upper surface of the rotary disc is tightened, and the wire on the lower surface is paid out (the wire on the upper surface is paid out of the shell, and the wire on the lower surface is still in the shell after the wire on the upper surface is taken up into the shell and the wire on the lower surface is paid out); the winding mode can be designed and changed according to the requirement, and the limitation is not to be taken as the limit.

The utility model is mainly designed in that the two turntables, the wire rods and the shell are combined to form the telescopic data line, and under the condition of the same wire rod length, compared with the traditional data line, the wire rod can be distributed on the two turntables with smaller diameters by the data line in the patent, so that the width of the shell can be designed to be smaller, the whole width of the data line is reduced, the data line can be easily placed in a pocket to be carried, and the carrying convenience of the data line is improved; meanwhile, the data line is in a strip shape, so that the hand feeling is better, the data line is convenient to hold by hands, and the use experience of the data line is better.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
