The invention relates to an electric-power device and specifically relates to a bottle taking device based on pinions and racks. The device includes a first protection box, the bottom end of which is provided with an open slot, a second protection box which is arranged to be vertical to the first protection box and a moving device used for loading a high-voltage insulating bottle. After the bottle taking device is fixed firmly through fixing holes, first cranks and second cranks are rotated and a position-limiting tray is transported to an appropriate position and after picking is completed, the first and second cranks are continued to be rotated to transport the insulating bottle to a storage position. The arrangement of the cranks is capable of reducing body movement of operation personnel so that risks of a work on a tower are reduced.
