[0058] Further, the ratchet 13 is a cross ratchet or a four-tooth ratchet.

[0059] It should be noted that the U-shaped component 1 can be in the form of a flexible branch support in specific use;

[0060] The use steps of the technical scheme of the embodiment of the application are as follows:

[0061] Firstly, the branch fixed guide rail base 2 in the EMU wire slot pre-assembly wiring branch tool is fixed on the pre-assembly table, which adopts a slidable track type, facilitating the disassembly of the U-shaped component 1, i.e. the flexible branch support, and the exchange of the position sequence of the flexible branch support during the branching process, thereby avoiding the adjustment of the cable carrying and the problem of cable knotting.

[0062] Secondly, the U-shaped component 1, i.e. the flexible branch support, in the EMU wire slot pre-assembly wiring branch tool is slid into the branch fixed guide rail base 2, and the corresponding U-shaped component 1, i.e. the flexible branch support, is selected according to the cable type and category required by the process;

[0063] The flexible branch support is made of 3D printed ABS plastic, which is resistant to chemical corrosion and heat, has a certain surface hardness, has high elasticity and toughness, and has the processing and molding characteristics of thermoplastic plastic and improved electrical properties;

[0064] 3D printing is convenient and relatively soft in texture and does not easily damage the cable, and can be manufactured again through 3D printing if damaged during use.

[0065] Thirdly, the cable classification nameplate 3 is installed on the U-shaped component 1, i.e. the flexible branch support, to facilitate the identification and differentiation of cable types and categories during the branching process, thereby improving the identification of the cable during the branching process.

[0066] Finally, according to the job instruction book and the branching table in the production process, the cable is placed in different U-shaped components 1, i.e. flexible branch supports, and the ratchet can be rotated by the weight of the cable or external force during the branching process, and the ratchet structure can prevent the cable from being squeezed and damaged during the branching process, and the internal ratchet structure can prevent the cable from jumping out during the wiring process, thereby preventing classification errors.

[0067] The EMU wire slot pre-assembly wiring branch tool of the embodiment of the application can be used repeatedly, and the U-shaped component 1, i.e. the flexible branch support, made of 3D printing also meets the subsequent cable requirements of different specifications.
