The threaded pressure rod is rotated to press the optical fiber to complete the clamping of the optical fiber in the cylindrical block. The slide plate and the cylindrical block with the optical fiber inserted are pushed by the pushing assembly to move toward the direction close to the grinding disk and the first motor is started to drive the grinding disk to rotate. When the polished end of the optical fiber contacts the grinding disk, the grinding disk polishes the end face of the optical fiber.
