As shown in fig. 2, the top plate assembly 2 includes a top plate 21. Above the top plate is mounted a wire inlet unit 5. The incoming line unit 5 comprises an inner support and a plurality of outer supports. The inner bracket is detachably fixed to the top plate 21. Specifically, the bottom of the inner bracket includes a first fixing edge, and the screw fixes the first fixing edge on the top plate 21.

A cable tie 52 is removably secured to the inner bracket. The wire binding rod 52 is fixed to the inside of the inner bracket by screws.

The inner bracket comprises a first folding edge group which is bent outwards and downwards. The outer bracket comprises a second flanging group which is bent inwards and upwards. A plurality of outer support lock is in the inner support outside, and the edge of first hem group and the edge butt joint of second hem group.

Specifically, the first folding group bends outwards and downwards, and the inner surface of the first folding group is tightly attached to the outer surface of the inner support. The second flanging group is bent inwards and upwards, and the outer surface of the second flanging group is tightly attached to the inner surface of the outer support. When the edge of the first flanging group and the edge of the second flanging group are butted, the outer surface of the first flanging group is attached to the inner surface of the outer support, and the outer surface of the second flanging group is attached to the outer surface of the inner support.

Adjacent outer brackets are detachably fixed together. Specifically, the side of the outer support is provided with a second fixing edge, and the second fixing edges of the adjacent outer supports are fixed together by screws.
