The two drive motors 4 are adjusted to be aligned with the clamping slot 30 that matches the size of the optical fiber 5 (this step can be ignored if it has been adjusted in advance). Then, the distance adjustment component 2 is used to adjust and reduce the distance between the first slider 11 and the second slider 12.
