Referring to FIGS. 1-4, during assembly of the hub 50 to the shell 40, the hub 50 is rotatably received in the shell 40 by the first pin 56 of the hub 50 passing through the first pin hole 422 of the first post 424 of the shell 40.

During assembly of the conductive cable 60 to the hub 50, the conductive cable 60 is wound around the main body 52 of the hub 50, and two ends of the conductive cable 60 pass through the first cable port 426 and the second cable port 442 respectively.

During assembly of the partition plate 70 to the hub 50, the partition plate 70 is fixed to the hub 50 by the second pin 58 of the hub 50 received in the second pin hole 72 of the partition plate 70.

During assembly of the resilient member 80 to the hub 70, the resilient member 80 is fixed to the partition plate 70 by the first fixed end 82 of the resilient member 80 being received between the shaft 74 and the two holding arms 76.

During assembly of the cover 90 to the resilient member 80, the partition plate 70, and the shell 40, the cover 90 covers the shell 40, the cover 90 is fixed to the resilient member 80 by the second fixed end 84 of the resilient member 80 being fixed to the fixed portion 96, and the partition plate 70 is rotatably received in the cover 90 by the shaft 74 of the partition plate 70 passing through the shaft hole 94 of the second post 92 of the cover 90.

The lamp 98 electrically connects with the one end of the conductive cable 60 through the second cable port 442. The other end of the conductive cable 60 is electrically connected with the power supply 20 through the first cable port 426 and the second through hole 206 of the power supply 20.
