The hardware includes a first terminal, a first connecting piece electrically connected to the first terminal, a second terminal, a second connecting piece electrically connected to the second terminal, and a dial piece in contact with the first connecting piece. The dial piece also contacts the swing rod and can be in contact or separated from the second connecting piece under the drive of the swing rod.
