The inside of the limiting groove 14 is slidably connected to a limiting block 15, and the middle of the limiting block 15 is fixedly connected to a movable rod 16, and a spring 17 is provided on the outside of the movable rod 16.

[0035] The baffle 12 protects the workers of the power transmission line to avoid safety accidents. The limit groove 14 is used to limit the movement range of the limit block 15 to prevent the baffle 12 from falling during the maintenance of the workers.
