[0024] The two ends of the partition plate abut against the two side plates of the box body, and the partition plate and the box body are connected through a damping rotating shaft. The damping rotating shaft ensures that the partition plate will not fall off when it is rotated to be opened.

[0025] Optionally, the hinge shaft is located at the upper end of the partition plate. When the partition plate is rotated, the edge of the partition plate will not be rotated into the inner cavity of the box body. The maximum rotation angle of the partition plate is 90°.

[0026] In some possible embodiments, when the partition plate assembly is one, the upper end of the partition plate assembly is rotatably connected to the side plates of the box body on both sides of the installation opening. The upper end of the partition plate assembly flows out of the installation position 7, and the lower end of the partition plate assembly is a horizontal plane. The partition plate assembly is flipped down until the lower end thereof abuts against the lower end of the installation opening, and the cable extends out of the installation position 7.

In order to facilitate operation, the plurality of partition plates are synchronously rotated to achieve complete opening and closing of the installation opening. The plurality of partition plates are connected by means of a linkage assembly. The linkage assembly has two, and the two linkage assemblies are located on the left and right sides in the installation opening. The two linkage assemblies are identical in structure and symmetrically arranged. When one of the partition plates is rotated, the two linkage assemblies are synchronously moved with the partition plate, thereby driving the other partition plates to be synchronously rotated.

That is, the extension rod 9 is always located in the inner cavity of the box body in different states of the partition.
