With the development of The Times, electric power transportation spans more and more distances, and the use of high-voltage transmission lines also increases. In the maintenance of high voltage transmission lines, the ground clip is often used as a temporary grounding protection device. Most of the existing ground clips in the market are manually operated, with low degree of automation, complicated operation steps, long time consumption and high working intensity. Therefore, we propose a kind of ground clips similar to manipulator, which is driven by a motor to reduce the working intensity of the staff.
