The shape of the end cover 6 is matched with the shape of the placing seat 3, and the inner side wall of the end cover 6 is in contact with the outer side wall of the placing seat 3. The limiting slot 30 and the oil injection hole 33 are covered by the end cover 6, so that the external dust or impurities can be prevented from entering the threaded hole 31, and the dustproof and waterproof effect of the threaded hole 31 is achieved. In addition, when the wiring work of the conductive sheet 2 is completed, the wiring part 20 is covered by the end cover 6, so that the waterproof ability of the wiring part is further improved.

[0026] As shown in Figure 2 , Figure 3 , the plastic cover body 1 is also integrally formed with a fixing seat 4, the fixing seat 4 is provided with a through hole 40, and the extending part 21 is arranged in the through hole 40.
