Live detection connecting device for lightning arrester

The lightning arrester live-line detection connecting device comprises two clamping blocks which are symmetrically arranged, a clamping seat which sleeves the same ends of the two clamping blocks, a sliding pipe which is fixedly arranged on one side, far away from the clamping blocks, of the clamping seat, and a collision block which sleeves the sliding pipe; the collision block is in sliding fit with the sliding pipe, the two clamping blocks are both in sliding connection with the clamping base, the matching faces of the two clamping blocks and the clamping base are both inclined faces, a check block is arranged at the end, away from the clamping base, of the sliding pipe, and a clamping opening is formed between the portions, away from the clamping base, of the two clamping blocks. An insulating rod used for lifting the two clamping blocks and driving the collision block to collide the clamping seat or the stop block is further arranged below the collision block, the clamping blocks are electrically connect
