In other embodiments, an outer convex ring may be additionally arranged on the outer circumferential wall of the first protection sleeve 5 and the second protection sleeve 6, and a groove is arranged inside the threading hole 43, so that the outer convex ring and the groove are fastened to each other to realize fixation. Therefore, the structure of how the first protective sheath 5 and the second protective sheath 6 are fixed on the threading hole 43 is not particularly limited.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
