[0002] Fiber cleavers or fiber laser cutting machines are usually used for fiber optic cutting.

[0026] Working principle: When in use, the utility model places the pre-treated and cleaned optical fiber on the inner side of the cutting table 16. When the optical fiber is placed on the inner side of the cutting table 16, the pressure plate 20 is swung. When the pressure plate 20 swings, the optical fiber on the inner side of the cutting table 16 is pressed and fixed. When the pressure plate 20 presses and fixes the optical fiber on the inner side of the cutting table 16, the push button 26 is pushed inward. When the push button 26 is pushed inward, the telescopic block 23 is driven to move linearly inward along the inner wall of the telescopic groove 21. When the telescopic block 23 moves linearly inward, it pushes the compression support spring 24 inward. At the same time, when the telescopic block 23 moves linearly inward, the compression support spring 24 is pushed inward. The plate 20 is kept horizontally aligned with the inner side of the U-shaped limiting enclosure 27. When the pressing plate 20 is kept horizontally aligned with the inner side of the U-shaped limiting enclosure 27, by releasing the push on the push button 26, when the push on the push button 26 is released, the elastic potential energy generated by the compression deformation of the support spring 24 will push the telescopic block 23 in the opposite direction to reset outward and move linearly. When the telescopic block 23 is reset outward and moves linearly, the telescopic block 23 will be inserted into the inner wall of the limiting groove 28. When the telescopic block 23 is inserted into the inner wall of the limiting groove 28, the pressing plate 20 can be limited and fixed by the telescopic block 23 cooperating with the limiting groove 28. When the pressing plate 20 is limited and fixed, it is convenient to press and fix the optical fiber.

[0027] At the same time, when the telescopic block 23 is inserted into the inner wall of the limit slot 28, the telescopic block 23 will press the contact switch 22. When the contact switch 22 is pressed, it will control the start of the drive motor 4. When the drive motor 4 is turned on, it will drive the transmission screw 5 to rotate. When the transmission screw 5 rotates, it will drive the lower slider 6 to move backward along the inner wall of the lower limit straight slide groove 3 due to the threaded connection. When the lower slider 6 moves backward in a straight line, it will drive the lower end of the first swing frame 7 to move backward. When the lower end of the first swing frame 7 moves backward, it will cooperate with the second swing frame 8 to drive the lifting platform 9 to move downward in sequence. At the same time, when the contact switch 22 is pressed, it will control the start of the cutting motor 12. When the cutting motor 12 is turned on, it will drive the cutting blade 13 to rotate. When the lifting platform 9 moves downward, it will synchronize The rotating cutting blade 13 and the upper rubber pad 15 are driven to move downward. When the upper rubber pad 15 moves downward, it will cooperate with the lower rubber pad 17 to press and fix the optical fiber cutting position. When the optical fiber cutting position is pressed and fixed, the downward moving cutting blade 13 can perform a preliminary cutting on the upper end of the optical fiber. When the upper end of the optical fiber is preliminarily cut, the electric push rod 18 is extended upward by control. When the electric push rod 18 is extended upward, it will drive the U-shaped extrusion block 19 to move upward. When the U-shaped extrusion block 19 moves upward, it will squeeze the lower end of the optical fiber cutting position. When the U-shaped extrusion block 19 squeezes the lower end of the optical fiber cutting position, the optical fiber cutting position can be pressed and broken, thereby achieving the pressing and fixing of the optical fiber while facilitating the cutting and breaking of the optical fiber.
