9. The method for using a variable hanging point conductor ladder head for a power transmission line according to claim 8, characterized in that: Also includes: S16, when in use, the top of the hanging rod (5) is fixed to the drone, and the hanging rod (5) is pulled up by the drone. When the hanging rod (5) is pulled up, the locking rod (4) is lifted. When the locking rod (4) is lifted up, the vertical rod body (41) moves upward, so that the opening on the side of the ladder head body (1) is opened, and the limit ring (42) and the vertical rod body (41) move synchronously, so that the limit ring (42) moves up to the top of the limit slide (14), and the limit ring (42) is blocked by the limit slide (14), so that the entire wire ladder head is lifted synchronously as a whole; S17, after the ladder head is hooked onto the conductor, the connecting lock (6) is unfastened, so that the lock male end (61) and the lock female end (63) are separated, so that the top of the locking rod (4) loses traction and naturally falls down, and the vertical rod body (41) is inserted into the locking slot (111) when falling, so that the opening on the side of the ladder head body (1) is closed, and the locking is completed; S18, when encountering a high tower, a small rope is placed on the pulley mechanism (2), and the small rope is used to pull the large rope to achieve the purpose of reducing friction; S19, when the rope is loaded, the movement direction of the rope is guided by the drainage mechanism (9).

10. Use of a transmission line variable hanging point conductor ladder head according to any one of claims 1 to 7 in circuit construction.
