Some wire winding devices use the traditional loop winding method, which cannot adjust the winding range of the wire, and it is easy to cause the wire to be tangled and knotted when taking out the wire, which is difficult to deal with; 2. Some wire winding devices use multiple storage boxes for storage, but after storage, it is impossible to access the wires individually and adjust the length in real time, and multiple storage boxes are arranged linearly, making it difficult to adjust the positions according to the orientation of the wires.

The upper wall of the cover shell is penetrated with a wire entry groove, and the lower wall of the cover shell is penetrated with a wire exit groove. The wire entry groove and the wire exit groove respectively penetrate the side wall of the cover shell away from the steering mechanism. The wire entry clamp mechanism is arranged in the wire entry groove, and the wire exit clamp mechanism is arranged in the wire exit groove.

[0025] The connecting mechanism 8 includes a connecting support column 81 and a rotating connecting ring 82. The connecting support column 81 is symmetrically arranged on both sides of the cover shell 51. The connecting support column 81 is cylindrical and opens to the outside. The rotating connecting ring 82 is rotatably arranged on the inner side of the connecting support column 81. A card slot 83 is penetrated on the side wall of the rotating connecting ring 82, and a magnetic plate is arranged on the inner side of the rotating connecting ring 82; the structure of the split winding assembly 4 is the same as that of the telescopic adjustable winding assembly 2. The two sides of the split winding assembly 4 are respectively provided with a connecting mechanism 8 and a hanging column 9. The hanging column 9 is movably inserted in the rotating connecting ring 82. A connecting magnetic plate 91 is arranged on the side wall of the hanging column 9. The connecting magnetic plate 91 is arranged corresponding to the magnetic plate in the rotating connecting ring 82. The split winding assembly 4 is connected to both sides of the telescopic adjustable winding assembly 2 in sequence through the hanging column 9.

[0026] Working principle and workflow: During specific use, the fixed plate 1 is attached to the inspection instrument close to the wire with double-sided tape, so that the telescopic adjustable winding assembly 2 is close to the root of the wire, and then the telescopic adjustable winding assembly 2 is held and pressed toward the steering mechanism 3, and the connecting plate 33 drives the pressing column 34 to slide into the active cavity 32, and the positioning spring 37 is compressed. Then the telescopic adjustable winding assembly 2 can be rotated to any angle, so that the wire entry clamp mechanism 54 is aligned with the root position of the wire, and then the telescopic adjustable winding assembly 2 is released. Under the elastic action of the positioning spring 37, the plug-in positioning block 35 is inserted into the positioning groove 36, thereby positioning the relative angle between the telescopic adjustable winding assembly 2 and the follow-up rotating column 11, and the rotation of the follow-up rotating column 11 facilitates the adaptive adjustment of the relative angle between the telescopic adjustable winding assembly 2 and the fixed plate 1, that is, the relative angle between the telescopic adjustable winding assembly 2 and the side wall of the instrument, to adapt to the position of different wires.

[0027] Then open the closing door 7 and check whether the winding columns 66 in each positioning cylinder 63 are screwed and fixed. The number of winding columns 66 to be installed can be selected according to the required winding length of the wire. Then, the adjusting screw 61 is turned as needed. Under the restriction of the adjusting groove 57, the adjusting block 62 engaged with the adjusting screw 61 moves upward, thereby driving one end of the pulling rod 64 to move upward. The length of the pulling rod 64 is fixed, and then the positioning cylinder 63 is pulled. The symmetrical positioning cylinders 63 slide toward each other under the restriction of the movable groove 56, thereby reducing the distance between the symmetrical winding columns 66 and reducing the winding range of the wire. Similarly, the adjusting screw 61 is turned in the opposite direction. Under the push of the pulling rod 64, the symmetrical positioning cylinders 63 slide away from each other, increasing the distance between the symmetrical winding columns 66 and increasing the winding range of the wire.

[0028] After adjusting the winding range according to the length of the wire to be wound, push the wire into the wire entry slot 52. Under the transition of the sliding transition rod 544, the wire directly slides between the symmetrical extrusion arc plates 542. The first slider 541 slides into the cover 51 under the extrusion. The spring connected to the first slider 541 provides elastic pressure to clamp the wire. Then, the wire inside the cover 51 is pulled onto the winding column 66 on one side. The wire tilts and presses the lower half of the extrusion arc plate 542. The extrusion arc plate 542 rotates adaptively on the first slider 541, and its upper part approaches the extrusion arc plate 542 on the other side to clamp the wire, thereby always clamping the wire when the wire is wound. The wire is wound in an 8-shaped trajectory onto the symmetrical winding posts 66. The winding posts 66 in the same row can be wound multiple times, but the multiple turns of wire need to be placed side by side on the winding posts 66 to avoid the wires from getting tangled when the wires are taken out. During the winding process, if it is found that there is a deviation in the winding range between the winding posts 66, the distance between the winding posts 66 can be adjusted at any time by turning the adjusting screw 61. After adjustment, the wire can be tightened. Finally, the wire is pushed into the wire outlet slot 53. Under the transition of the transition inclined plate 553, the wire slides between the symmetrical clamping arc plates 552. The second slider 551 slides into the cover shell 51 under extrusion. The spring connected to the second slider 551 provides elastic pressure to clamp the lower end of the wire, which is suitable for wires of various specifications.

[0029] Finally, close the closing door 7, the first magnetic block 58 and the second magnetic block 71 are attracted, and the pressure pad 72 is in contact with the winding column 66 to prevent the wire from loosening and falling off. Then, the split winding component 4 is installed on both sides of the telescopic adjustable winding component 2 in sequence according to the number of wires, and the hanging column 9 is inserted into the rotating connecting ring 82 from top to bottom. The magnetic plate in the rotating connecting ring 82 is magnetically fitted with the connecting magnetic plate 91, so that the hanging column 9 and the rotating connecting ring 82 are relatively fixed, and the rotating connecting ring 82 rotates in the connecting support column 81, so that the relative position of the split winding component 4 and the telescopic adjustable winding component 2 can be adaptively adjusted according to the relative position between the wires, thereby improving the flexibility of the device; according to the above-mentioned wire winding steps, the split winding component 4 is used to fix the wires in sequence.

[0030] When the wire does not need to be wound, the closing door 7 can be directly opened, and the wire can be pulled down from the winding column 66 from bottom to top and taken out. The split winding components 4 and the telescopic adjustable winding component 2 do not interfere with each other, and the wires can be taken or adjusted separately. In the process of using the wire, if it is found that the wire is not long enough, the winding column 66 can be rotated from the rear wall of the cover shell 51 to make the screw thread 67 disengage from the restriction of the installation thread 65, and then the winding column 66 can be pulled out to release the wire wound thereon, and then the wire can be pulled. The operation is convenient, and the transparent closing door 7 can observe the condition of the wound wire in the cover shell 51 at any time.

[0031] The above is the overall workflow of the present invention, and you can repeat this step next time you use it.
