5. A cable threading and arranging auxiliary tool according to claim 1, characterized in that the driving member (6) is divided into N segments, one of which is connected to the holder (1) closest to the threading end of the cable, and the remaining driving member (6) of each segment is adapted to connect two adjacent holders (1).
6. The auxiliary tool for threading and arranging cables according to claim 2, wherein the two sides of the bracket (9) are respectively provided with an A groove and a B groove, the A groove can be matched with the outer side of a new cable, the B groove can be matched with the outer side of an old cable, the B groove is internally provided with a rolling body II, and the rolling body II can be contacted with the outer side of the old cable.
7. A cable threading and arranging auxiliary tool according to claim 2, characterized in that the connecting piece (10) comprises a plug (101) connected with the retainer (1) and a jack (102) matched with the plug (101), the jack (102) is arranged on the bracket (9), and when the second control piece (11) applies a pulling force of the reverse bracket (9) to the retainer (1) to enable the retainer (1) to move towards the inner side of the retainer (1), the plug (101) is separated from the jack (102), and the retainer (1) is separated from the bracket (9).
8. A cable threading and arranging auxiliary tool according to claim 2, characterized in that the guide (12) comprises a sliding rail arranged between the holders (1) and a slider (13) cooperating with the sliding rail, the slider (13) being connected to the holders (1), the guide (12) being connected to a single holder (1) distributed at the end and remote from the inlet of the arranging plug.
