[0032] Next, in conjunction with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figure 1 and Figure 2 FIGS., an embodiment provided by the present utility model: A battery cell collection wire group convenient to use, including a collection wire harness 1. A cylindrical sleeve 2 is provided on the side wall of the collection wire harness 1. The cylindrical sleeve 2 is slidably connected to the side wall of the collection wire harness 1. A first fixing block 6 is fixedly connected inside the cylindrical sleeve 2. A first stretching block 7 is fixedly connected to the side wall of the first fixing block 6. A threaded groove 8 is provided on the side wall of the first stretching block 7. A tightening groove 9 is provided inside the first stretching block 7. A second fixing block 10 is fixedly connected inside the first stretching block 7. A second stretching block 11 is fixedly connected to the side wall of the second fixing block 10. The inner wall of the first stretching block 7 is attached to the side wall of the second stretching block 11. The second stretching block 11 is slidably connected to the side wall of the collection wire harness 1. A nut 12 is provided on the side wall of the collection wire harness 1. The nut 12 is threadedly connected inside the threaded groove 8. A first magnetic attraction block 3 is provided inside the cylindrical sleeve 2. An identification plate 4 is provided on the upper surface of the cylindrical sleeve 2. A second magnetic attraction block 5 is provided on the lower surface of the identification plate 4. The first magnetic attraction block 3 attracts the second magnetic attraction block 5;

[0034] During the process of operating this precision device, if it is necessary to clearly distinguish the collection wire harness 1, first, prepare an identification plate 4 with a specific identification. This identification plate 4 will be tightly adsorbed on the side wall of the cylindrical sleeve 2 through the attraction of the first magnetic attraction block 3 and the second magnetic attraction block 5, so that the collection wire harness 1 can be accurately distinguished. Next, put the cylindrical sleeve 2 on one end of the collection wire, ensure that its position is fixed, and then, by rotating the nut 12 clockwise, the first stretching block 7 is gradually tightened. Due to the tightening of the first stretching block 7, the second stretching block 11 connected thereto will also be gradually tightened and finally tightly fixed on the side wall of the collection wire. This step is very crucial because it can effectively prevent the collection wire from accidentally slipping during the operation of the device, thus ensuring the safety and stability of the device.

[0035] Referring to Figure 1 Figure 4 and Figure 5, a stretching ring 13 is provided on the side wall of the acquisition wire harness 1. A guiding column 14 is fixedly connected to the side wall of the stretching ring 13. A contraction assembly is provided on the side wall of the stretching ring 13. The contraction assembly includes a telescopic belt 15. The side wall of the telescopic belt 15 is fixedly connected to the side wall of the stretching ring 13. A locking belt 17 is fixedly connected to the side wall of the stretching ring 13. A slider 19 is fixedly connected to the side wall of the telescopic belt 15. The inside of the slider 19 is slidably connected to the side wall of the locking belt 17. A pressing block 20 is slidably connected to the inside of the slider 19. A fixing plate 21 is provided inside the slider 19. A first spring 22 is provided inside the slider 19. A second spring 23 is provided inside the slider 19. One end of the first spring 22 is fixedly connected to one side of the fixing plate 21, and the other end of the first spring 22 is fixedly connected to the side wall of the right pressing block 20. One end of the second spring 23 is fixedly connected to the other side of the fixing plate 21, and the other end of the second spring 23 is fixedly connected to the side wall of the left pressing block 20. A clamping block 16 is provided on the side wall of the locking belt 17. A clamping groove 18 is formed inside the locking belt 17. The side wall of the pressing block 20 is slidably connected to the inside of the clamping groove 18.

[0036] After the preliminary differentiation of the acquisition wire harness 1 is completed, the next step is to thread it into the heat-shrinkable sleeve. During this process, first, by pressing the pressing block 20, the pressing block 20 is disengaged from the inside of the clamping groove 18 and slides into the inside of the slider 19. This action is completed by the contraction of the first spring 22 and the second spring 23. Subsequently, the slider 19 needs to be slid along the side wall of the locking belt 17, which can cause the stretching ring 13 to contract, thereby fixing the acquisition wire harness 1. This step is to ensure that the acquisition wire harness 1 is fixed in place in the heat-shrinkable sleeve and reaches the required tightness. When the acquisition wire harness 1 is fixed, the pressing block 20 can be released at this time, enabling the first spring 22 and the second spring 23 to rebound and recover. This recovery process will push the slider 19, causing it to snap back into the inside of the clamping groove 18, thereby further fixing the acquisition wire harness 1. Finally, the guiding column 14 needs to be passed through the heat-shrinkable sleeve, which can drive the acquisition wire harness 1 to pass through the heat-shrinkable sleeve together. Through this step, it can be ensured that the acquisition wire harness 1 is completely threaded into the heat-shrinkable sleeve, completing the entire threading process.

[0037] Working principle: When using this device and it is necessary to distinguish the acquisition wire harness 1, first, the prepared identification plate 4 is attached to the side wall of the cylindrical sleeve 2 by the attraction between the magnetic attraction block 3 and the magnetic attraction block 5. Then, the cylindrical sleeve 2 is sleeved on both ends of the acquisition wire. Next, by tightening the nut 12, the stretching block 7 is slowly tightened. Due to the tightening of the stretching block 7, the stretching block 11 is also slowly tightened, thereby fixing it on the side wall of the acquisition wire to prevent it from slipping during use. After the distinction is completed, when the acquisition wire harness 1 needs to be inserted into the heat shrinkable sleeve, at this time, by pressing the pressing block 20, the pressing block 20 is disengaged from the inside of the card slot 18 and slides into the inside of the slider 19, thereby causing the first spring 22 and the second spring 23 to contract. Then, the slider 19 is slid on the side wall of the locking band 17 to contract the stretching ring 13 and fix the acquisition wire harness 1. When the required tightness is reached, at this time, the pressing block 20 is released, and the first spring 22 and the second spring 23 rebound and recover, thereby pushing the slider 19 and reinserting it into the inside of the card slot 18 to achieve the effect of fixing it. Finally, by passing the guide post 14 through the heat shrinkable sleeve, the acquisition wire harness 1 is led through the heat shrinkable sleeve, thus completing the wire threading process.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
