The top of the support plate 603 contacts the bottom of the cover plate 3, limiting the cover plate 3 from moving downward. The clamping bolt 503 is rotated to move the clamping bolt 503 forward. The clamping bolt 503 is tightened. During the movement, the movable plate 502 is driven to move forward, so that the movable plate 502 is out of contact with the card plate 501, and the movable plate 502 is moved upward. The movable plate 502 rotates around the rotating shaft 8, and the fixing bolt 204 is rotated. The fixing bolt 204 drives the branch plate 201 to move forward, and the fixing bolt 204 is out of contact with the box body 101. The branch plate 201 is moved forward to disengage the branch plate 201 from the box body 101, and the line is stably connected to the terminal 103, and the line is moved to the front side of the card plate 501, and the movable plate 502 is moved downward. 02, the bottom of the movable plate 502 contacts the clamping bolt 503, and the clamping bolt 503 is rotated to move the clamping bolt 503 backward. During the movement of the clamping bolt 503, the movable plate 502 is driven to move backward. The movable plate 502 moves to the inside of the card plate 501 and remains stable. The line is fixed by the movable plate 502 and the card plate 501, so that the line remains stable. The line is separated according to the direction of the line, and the two sliders 203 are aligned with the bottom of the left and right sides of the box body 101. The distribution board 201 is moved backward. The line is located inside the branching slot 202, and the fixing bolt 204 is rotated. The fixing bolt 204 is screwed into the inside of the box 101, driving the branching plate 201 to move backward, so that the rear side of the branching plate 201 contacts the box 101, thereby separating the line, and moving the support plate 603 backward. The support plate 603 is out of contact with the cover plate 3, and the cover plate 3 is moved downward. When the cover plate 3 is reset, the fixing spring 702 rebounds and drives the two fixing rods 703 to insert into the inside of the cover plate 3, limiting the movement of the cover plate 3, so that the cover plate 3 is fixed and stable to the box 101.
