Shaft sealing structure for column box type high-voltage switch

The utility model provides a shaft sealing structure for a column box type high-voltage switch. The shaft sealing structure comprises a first shaft sleeve, a second shaft sleeve, a fastening bolt and a connecting shaft, the inner diameters of the first shaft sleeve and the second shaft sleeve are the same as the outer diameter of the connecting shaft; the connecting shaft sequentially penetrates through the second shaft sleeve and the first shaft sleeve to enter a box body driving transmission part of the high-voltage switch; the fastening bolt sequentially passes through the bolt hole and the fixing hole and is used for fixing the first shaft sleeve and the second shaft sleeve on the box body wall of the high-voltage switch; according to the shaft sealing structure for the column box type high-voltage switch, the waterproof performance of the box body of the high-voltage switch can be ensured by utilizing the embedding effect between the first coupling part of the first shaft sleeve and the box body wall of
