[0035] By adopting the above technical solution, the connection between the fixing frame 11 and the closed door 12 is made more stable, and the number of fixing screws between the fixing frame 11 and the closed door 12 is reduced.

[0036] Working principle: First, push the connecting plate 191 to move, drive the moving plate 17 to move in the direction of the spring 16, and the moving plate 17 drives the card plate 18 to move. At the same time, the spring 16 is squeezed. At this time, insert the connecting rod 13 into the installation box 15, stop pushing the connecting plate 191, so that the moving plate 17 drives the card plate 18 to move in the opposite direction under the elastic force of the spring 16, so that the card plate 18 enters the fixing groove 14, so that the closed door 12 is initially fixed. When you want to disassemble it, push the connecting plate 191 in the direction of the spring 16 to make the card plate 18 is pulled out from the fixing groove 14, thereby completing the disassembly, thereby reducing the use of fixing screws, facilitating the installation and disassembly of the closed door 12, and saving the time of the staff; by driving the rotating rod 26 to rotate, the second gear 25 is driven to rotate, the second gear 25 drives the first gear 24 to rotate, and the first gear 24 drives the sleeve 22 to rotate. The rotation of the sleeve 22 causes the threaded rod 23 to move downward, so that the threaded rod 23 enters the predetermined fixing hole in the cross arm of the line tower, thereby facilitating the subsequent fixing of the grounding box 1 on the line tower and reducing shaking.
