s2, placing optical fibers: placing the processed optical fiber preform into the pushing device 2 through the feeding hole 12a manually or mechanically;

s3, optical fiber heating: the pushing device 2 fixes the outer wall of the optical fiber perform rod and then alternately operates to move the optical fiber perform rod to the right side, and when the right side of the optical fiber perform rod moves into the heating machine 3, the optical fiber perform rod stops moving and is heated by the heating machine 3;

s4, pushing and beating the optical fiber: after the right side of the optical fiber perform rod is heated to a specified temperature, the optical fiber perform rod is driven to move towards the right side through the pushing device 2, the heated optical fiber perform rod is pushed towards the left side through the wire drawing device 4, the diameter of the right side of the optical fiber perform rod is reduced, and the optical fiber perform rod with the reduced diameter is moved into the shaping cylinder 42 through the pushing device 2;

s5, fiber drawing: the optical fiber perform moved to the right end of the shaping cylinder 42 is clamped and fixed through the wire drawing mechanism 43, and when the optical fiber perform is filled in the right side of the shaping cylinder 42, the optical fiber perform is pulled out towards the right side through the wire drawing mechanism 43;

s6, cooling the optical fiber: the drawn optical fiber preform is wind-cooled by the cooling mechanism 44.

The mounting block 41 has a trapezoidal structure with a gradually decreasing width from the left side to the middle.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention as hereinafter claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
