[0034] The support ring 9 is located at the through hole, and both ends of the support ring 9 extend out of the shell 1 3 and the shell 2 4 respectively. The inner diameter of the support ring 9 is consistent with the diameter of the rotating shaft 8, and the diameter of the support ring 9 is consistent with the diameter of the contact ring 11.
