2. The bare fiber polishing apparatus according to claim 1, wherein: the driving mechanism (9) comprises a main shaft (901) fixed at the center of the grinding seat (8), an annular groove (902) formed in the circumferential surface of the main shaft (901), a mounting groove is formed in the inner wall of the annular groove (902), a driving gear (904) is rotatably arranged in the mounting groove, a micro motor (903) is also arranged in the annular groove (902), an output shaft of the micro motor is fixedly connected with the driving gear (904), a rotating ring (905) is sleeved in the annular groove (902), and an inner gear ring (906) is meshed with the driving gear (904).
3. The bare fiber polishing apparatus according to claim 1, wherein: the magnetic component A (5024) is provided with a strip-shaped opening (5026) which is used for providing an installation space for the elastic component (5042), after the gland (6) is opened, the magnetic component A (5024) moves upwards, the strip-shaped opening (5026) pulls the elastic component (5042) upwards, and the magnetic component B (5041) is further driven to move towards two sides.
