[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] like Figure 1 , Figure 2A cable threading combination tool is shown, which is used to play an auxiliary guiding role in the threading process of the cable S, so as to help the staff to quickly thread the cable S on some complex and difficult-to-thread paths.

[0035] The above-mentioned cable threading combination tool includes a fixing member 100, a pulling member 200 and a clamp. The fixing member 100 is used to be fixed on the end of the cable S so as to facilitate the connection and fixation between the pulling member 200 and the end of the cable S; the above-mentioned pulling member 200 is used to be threaded on the laying path of the cable S to pull and guide the movement of the cable S; the above-mentioned clamp is used to pull the pulling member 200 when threading the pulling member 200 so that the pulling member 200 can be quickly and conveniently threaded on the threading path of the cable S.

[0036] The fixing member 100 includes a clamping portion 11 for connecting the end of the cable S and a first connecting portion 12 connected to the clamping portion 11. The pulling member 200 includes a second connecting portion 21, a wire portion 212; a second portion; 22 and a through portion 23. The second connecting portion 21 and the through portion 23 are respectively arranged at the two ends of the wire portion 212; the second portion; 22. The second connecting portion 21 can be selectively detachably connected to the first connecting portion 12. The first connecting portion 12 and the second connecting portion 21 are mutually connected to achieve the effect of connecting and fixing the fixing member 100 and the pulling member 200. The wire portion 212; the second portion; 22 are made of materials with high pulling strength such as steel wire and nylon. The wire portion 212; the second portion; 22 are relative to The cable S is softer and easier to be threaded in some relatively complex and difficult-to-thread places (in narrow and curved spaces). The clamp can be optionally connected to the outlet portion 23. When the outlet portion 23 encounters a situation where it is difficult to thread during the threading process, the staff can use the clamp to clamp and fix the outlet portion 23 and then pull the pulling portion so that the pulling member 200 can be completely threaded in the threading path of the cable S. When threading the cable S, the pulling member 200 is pulled and guided to pull the cable S, so that the cable S can follow the movement of the pulling member 200 and be threaded along the threading path of the cable S, thereby reducing the difficulty of threading the cable S in some relatively complex and difficult-to-thread places (in narrow and curved spaces).

[0037] The following will introduce the technical details of each component one by one.

[0038] In some embodiments, the clamping portion 11 includes a clamping cylinder 111 and a tightening sleeve, wherein the clamping cylinder 111 is connected to the tightening sleeve, and the clamping cylinder 111 is provided with a penetration channel 01, and the penetration channel 01 is used for the end of the cable S to pass through; wherein the tightening sleeve can be moved from a first predetermined position to a second predetermined position to increase or decrease the inner diameter of the penetration channel 01. When the end of the cable S is disposed inside the penetration channel 01, the movable tightening sleeve reduces the inner diameter of the penetration channel 01, thereby clamping and fixing the end of the cable S.

[0039] like Figure 1 , Figure 2 As shown, the side of the clamping cylinder 111 is provided with a thread, and the shrinking sleeve 112 is threadedly connected to the clamping cylinder 111. When the shrinking sleeve 112 is threadedly rotated relative to the clamping cylinder 111, the shrinking sleeve 112 can squeeze the clamping cylinder 111 inward to reduce the inner diameter of the threading channel 01 so as to clamp and fix the end of the cable S. In this way, the fixing member 100 can be quickly fixed to the end of the cable S to facilitate the threading of the cable S.

[0040] Further, please refer again to Figure 2 As shown, the side of the shrink sleeve 112 is provided with a parallel cut surface 05 , which is used for clamping and fixing with a wrench in actual use, so that the staff can further tighten and fix the fixing piece 100 to the end of the cable S.

[0041] It is understandable that in order to reduce the resistance encountered by the penetration portion 23 during the penetration process, Figure 1 As shown, the shape of the protruding portion 23 may be an ellipsoid with a surface halo.

[0042] In some embodiments, the surface of the line portion 212; the second portion; 22 is covered with an insulating material. The above design can prevent the current carried by the cable S from being conducted through the line portion 212; the second portion; 22, thereby protecting the staff and preventing safety accidents caused by leakage.

[0043] In some embodiments, Figure 3 , Figure 6 As shown, the first connection part 12 is in a ring shape, and correspondingly, the second connection part 21 is in a hook shape. The above structure facilitates quick connection between the first connection part 12 and the second connection part 21.

[0044] In some embodiments, Figure 4 As shown, the first connection part 12 is provided with a notch 02 ; in actual use, the second connection part 21 can be inserted from the side of the first connection part 12 through the notch 02 , further facilitating the connection and fixation between the first connection part 12 and the second connection part 21 .

[0045] In addition to the above structures, Figure 5 , Figure 7 As shown, the first connection part 12 has a connection neck at one end close to the clamping part 11, and a slot 03 is formed at the connection neck; correspondingly, the second connection part 21 is a bifurcated structure, and the second connection part 21 can be selectively connected to the first connection part 12 by engaging the slot 03. In actual use, the first connection part 12 and the second connection part 21 can be quickly connected by engaging the bifurcated structure with the slot 03.

[0046] Specifically, Figure 7 As shown, the second connecting portion 21 includes a first portion 211 and a second portion, the first portion 211 and the second portion are connected and arranged relatively to each other, the first portion 211 and the second portion form a forked structure, and the free ends of the first portion 211 and the second portion are both provided with a guide structure 04, which can play a guiding role in the process of being inserted into the card slot 03, thereby reducing the difficulty of aligning the first connecting portion 12 and the second connecting portion 21 when they are connected to each other.

[0047] In some embodiments, Figure 8 As shown, the cable threading assembly tool provided by the present application further includes an insulating rod 300, which includes a rod portion 31 and a connecting portion 32, wherein the rod portion 31 and the connecting portion 32 are connected, and the connecting portion 32 is used to selectively connect to the cable S. In actual use, the staff can adjust the position of the cable S during the threading process of the cable S by operating the insulating rod 300, which helps to quickly thread the cable S.

[0048] Furthermore, the rod portion 31 is a rod body provided with a telescopic structure or a splicing structure, and the staff can adjust the length of the insulating rod 300 according to the use requirements, thereby enhancing the adaptability of the insulating rod 300.

[0049] like Figure 8 , Fig. 9 As shown, the rod 31 includes at least one splicing body 311, and the two ends of the splicing body 311 are respectively provided with a first splicing structure and a second splicing structure that match each other, and the first splicing structure and the second splicing structure can be spliced ​​with each other; specifically, the first splicing structure and the second splicing structure are respectively threaded holes and studs, and two adjacent splicing bodies 311 are spliced ​​with each other by screwing together, and the staff can select a suitable number of splicing bodies 311 to connect end to end according to the operation needs to obtain an insulating rod 300 of a suitable length, thereby facilitating the installation of the cable S. In addition to the above effects, the splicing structure of the rod 31 can also facilitate the placement and storage of the insulating rod 300. When storing, only the splicing body 311 of the rod 31 needs to be disassembled, thereby reducing the space occupied by the insulating rod 300 when stored.

[0050] In some embodiments, the cable threading combination tool provided in the present application also includes a pulley device, which is used to be set at the corner of the cable S threading path to thread the cable S. The pulley device can greatly reduce the friction resistance of the cable S during the threading process, and the pulley device can also change the threading direction of the cable S on a complex threading path, making the threading process of the cable S more convenient and labor-saving.

[0051] The present application also provides a cable threading method, the cable threading method, the cable threading assembly tool, the cable threading method comprising:

[0052] The clamping part 11 of the fixing member 100 is fixed to the insertion end of the cable S, and then connected to the first connection part 12 through the second connection part 21, and then the passing part 23 is used to pass the cable S on the passing path. When encountering a complex path that is difficult to pass, the clamp is used to clamp and pull the passing part 23 so that the line part 212; the second part; 22 of the pulling member 200 is passed along the passing path of the cable S. Finally, the pulling member 200 is pulled at the end where the passing part 23 is located so that the pulling member 200 can drive the cable S to pass on the predetermined path. The guiding method of the pulling member 200 makes it easier to pass the cable S on a narrow and complex path.

[0053] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
