[0056] In other embodiments, the number of the first threading holes 11 on the threading plate 10 and the number of the second threading holes 21 on each first cover 20 can be adaptively adjusted according to actual needs, and no specific limitation is made here.

[0057] In an optional embodiment, the first cover 20 can be made of rubber or plastic. In order to realize the detachable setting of the first cover 20, the first cover 20 can be interference-fitted with the first threading hole 11, the connection is stable and the disassembly and installation of the first cover 20 is convenient, the operation convenience is improved, and the sealing performance can be ensured. In another optional embodiment, the first cover 20 can also be threadedly matched with the first threading hole 11. The second cover 30 is similar, and will not be described here.

[0058] In an optional embodiment, if Figure 2 As shown, the threading assembly also includes a first sealing sleeve 12, which is protruding from the outlet side 14 of the threading plate 10 and is arranged around the circumference of the first threading hole 11. When the first cable 100 is inserted into the first threading hole 11, the first sealing sleeve 12 can seal the circumference of the first cable 100, thereby effectively reducing the risk of water leakage.

[0059] In an optional embodiment, if Figure 2 As shown, the threading assembly also includes a second sealing sleeve 24, which is protruding from the outlet side 14 of the first cover 20 and is arranged around the circumference of the second threading hole 21.
