In a first configuration, the first handle is rotatable relative to the second handle about a rotation axis. In a second configuration, the first handle is non-rotatable relative to the second handle when an applied force applied to the first handle in a rotation direction is equal to or less than a predetermined amount. The first handle is rotatable relative to the second handle when the applied force is greater than the predetermined amount.
