The at least two leaf springs overlap in a vertical direction, and the at least two leaf springs decrease in length gradually from bottom up. The at least two leaf springs include a first leaf spring and a second leaf spring. The first leaf spring is longer than the second leaf spring. The leaf spring connecting component is configured to fixedly connect body portions of the at least two leaf springs in a length direction. The two first lifting ears are respectively disposed at two first free ends of the first leaf spring in the length direction, and the two second lifting ears are respectively disposed at two second free ends of the second leaf spring in the length direction.
