And the height of the top cover relative to the box body can be adjusted, and after adjustment, it is fixed by the second locking bolt 8.6 (when the length of the third cable 12 is longer, the length of the winding at the fixed rod 5.1 and the movable rod 5.2 is longer, the top cover is fixedly connected with the box body and has a certain gap between the substrate 3; when the length of the third cable 12 is shorter, the length of the winding at the fixed rod 5.1 and the movable rod 5.2 is shorter, so that the top cover can abut against the substrate 3).
