[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 - Figure 2 , Figure 6 - Figure 8 As shown, a rapid fiber optic cutting device includes a support base 1, a cutting cover 2 hinged to the side of the support base 1 via a pivot, an optical fiber body 4 snapped onto the top of the support base 1, two limiting components 5 fixedly installed on the right side of the top of the support base 1, and a cutting component 3 slidably installed inside the right side of the support base 1.

[0034] The cutting component 3 comprises a moving slide 31, a limiting slide block 32 fixedly installed on the left side of the moving slide 31, a pushing block 34 fixedly installed on the right middle part of the moving slide 31, a cutting assembly 35 fixedly installed on the middle part of the moving slide 31, a pulling rope displacement sensor 33 fixedly installed on one end of the moving slide 31, a fixed block 36 fixedly installed on the top of the moving slide 31 and close to one side of the pulling rope displacement sensor 33, a first connecting block 37 fixedly installed on one side of the top of the fixed block 36, a detection wire 38 fixedly connected to the top of the first connecting block 37, a second connecting block 310 fixedly installed on the other side of the top of the fixed block 36, and a pressure sensor 39 rotatably installed in the second connecting block 310. The pressure sensor 39 movably sheaths the outer surface of one end of the detection wire 38. A limiting bead 311 is fixedly installed on the end of the detection wire 38 close to the pressure sensor 39. A pressure spring 312 movably sheaths the outer surface of one end of the detection wire 38 and is located between the pressure sensor 39 and the limiting bead 311.

[0035] The first connecting block 37 is located on one side of the pulling rope displacement sensor 33, the height of the first connecting block 37 is higher than the height of the second connecting block 310, and the detection wire 38 is in an inclined state.

[0036] When the pushing block 34 is pushed and the moving slide 31 moves in the sliding groove 15, the detection wire 38 contacts the surface of the optical fiber body 4, the distance of the moving slide 31 is detected by the pulling rope displacement sensor 33, the position and height of the detection wire 38 are determined, and the position and height of the optical fiber body 4 are determined. That is, when the detection wire 38 contacts the optical fiber body 4, the detection wire 38 is pulled, the pressure spring 312 is compressed, and the pressure sensor 39 senses the pressure of the pressure spring 312. At this time, the distance of the displacement of the moving slide 31 is detected by the pulling rope displacement sensor 33 and is used as an initial value. Subsequently, before the optical fiber body 4 is cut, when the detection wire 38 contacts the side edge of the optical fiber body 4 during the movement of the moving slide 31 by pushing the pushing block 34, the distance difference between the distance of the displacement of the moving slide 31 and the initial value of the moving slide 31 is determined according to the detection of the pulling rope displacement sensor 33. When the distance of the displacement of the moving slide 31 is greater than the initial distance, the pulling rope displacement sensor 33 controls the lifting motor 352 to work through an electric signal, and the fixed knife block 354 drives the cutting blade 355 to rise to a corresponding value. When the distance of the displacement of the moving slide 31 is smaller than the initial distance, the cutting blade 355 is lowered to a corresponding value through an electric signal of the pulling rope displacement sensor 33. Thus, the automatic lifting and adjustment of the cutting blade 355 are realized. The cutting blade 355 is suitable for optical fiber bodies 4 of various thicknesses, and the cutting blade 355 can be automatically adjusted before each cutting, manual adjustment is reduced, and the cutting efficiency of the optical fiber body 4 is improved.

[0037] The first connecting block 37 is higher than the first pad block 14, and the height of the first connecting block 37 is the same as the thickness of the first clamping block 23, so that the detection wire 38 and the first connecting block 37 do not affect the closure between the support base 11 and the flip cover 21 when the support base 11 and the flip cover 21 are closed.
