Single inhaul cable clamping device and using method thereof

The invention provides a single inhaul cable clamping device and a using method thereof, and belongs to the field of automobile skylight inhaul cable assembling. The movable part is arranged on the device main body, vertically moves and is at least provided with an initial position, a first position and a second position from bottom to top; the clamping part is arranged on the movable part and clamps or releases the single inhaul cable; when the sensing assembly senses that the inhaul cable exists in the clamping part when the movable part moves to the first position from the initial position, the clamping part clamps the inhaul cable; when the induction assembly induces that no inhaul cable exists in the clamping part when the movable part is located at the first position, the movable part continues to move until the movable part stops at the second position, and when the induction assembly induces that the inhaul cable exists in the clamping part, the clamping part is clamped; the sensing assembly detects w
