The pole includes a substrate and a lead-out portion disposed on the substrate, where the lead-out portion includes a first portion, a second portion, and a mounting hole. The second portion is connected to an end of the first portion away from the substrate. The mounting hole is connected to the first portion and the second portion, where an opening of the mounting hole is located in the second portion. In a direction parallel to the substrate, minimum cross-sectional area of the first portion is greater than maximum cross-sectional area of the second portion. The pole has the first portion and the second portion of different cross-sectional areas disposed on the lead-out portion so that the second portion can be more easily riveted and bent against the first portion during riveting.
