In other embodiments, the offset groove 221A may also be biased toward the first abutting portion 222A, so that the first abutting portion 222A is a cantilever structure, or the offset groove 221A is a "T" type structure, so that the first abutting portion 222A and the second abutting portion 223A are both cantilever structures.

The specific structure and shape of the first pushing groove wall 42A and the second pushing groove wall 43A are not limited as long as they can provide a portion for pushing against the movable spring 22A, for example, in this embodiment, the first pushing groove wall 42A is bent in a substantially Z-shape, the second pushing groove wall 43A extends in a substantially in a "line shape, and both have the first contact 42A1 and the second contact 43A1 to push the movable spring 22A.
