A positioning hole 703 is opened, which is convenient for adjusting and assembling the gap between the vertical positioning base 200 and the vertical clamping base 300, and the operation process is relatively convenient. The reference base 100 is made of metal material, which is convenient for the reference base 100 and the optical fiber magnetic clamping block 400 to be adsorbed on each other.
