The clamping device for optical fiber fusion tapering machine provided by the present invention uses an electromagnet and a pressure hammer with a soft magnetic material to clamp the optical fiber, and the electromagnetic force generated by the electromagnet can be obtained by changing the current in the electromagnetic coil or whether the current is present or not. Adjust the electromagnetic suction and pressing force between the pressure hammer and the fixture seat. When the optical fiber needs to be clamped, the electromagnetic coil is energized, and the electromagnet generates electromagnetic force to attract the pressure hammer to the fixture seat. The groove fits to clamp the optical fiber in it; when the optical fiber needs to be removed after the sintering and melting of the optical fiber, the electromagnetic control unit controls that there is no current in the electromagnetic coil, and the electromagnetic force of the electromagnet disappears, so it is much easier to remove the pressure hammer. Simple, low working intensity; In addition, when adjusting the alignment position of the optical fiber clamping, the electromagnetic control unit controls the current of the electromagnetic coil to be at a relatively low current value, and the electromagnetic force of the electromagnet is relatively small, so that the pressure hammer forms a force on the optical fiber.
