The invention belongs to the technical field of electrical engineering, and particularly relates to a detachable multifunctional threader suitable for a curved path. The detachable multifunctional threader comprises a vertical bracket, a cable fixing device is connected between a threader cable residue and a threader cable body, and the other end of the threader cable body is connected to the vertical bracket. The threader is provided with a light source signal guiding device, no auxiliary guidance need to be additionally carried out, and therefore the safety performance of operation is improved. During threading in the curve path, smooth threading can be carried out, the disadvantages of a current threader are avoided, and the threading work is easier and more efficient. A required cablecan be fixed to the threader easily and firmly, and the cable can be fixed without using additional time-consuming and consumable means such as packaging tapes and ribbons. Moreover, the threader cable body is decomposable, the practical operation problem that prior like equipment is cumbersome and difficult to operate are solved, the work intensity of an operator is reduced, and the work efficiency can be greatly improved.
