The surfaces are fixedly connected with a fixing plate 15, the inner surfaces of the two fixing plates 15 are rotatably connected with two first rotating shafts 16, the outer surfaces of the four first rotating shafts 16 are fixedly connected with a U-shaped wheel 17, the outer surfaces of the four U-shaped wheels 17 are adapted to the outer surface of the cable 11, the outer surfaces of the four U-shaped wheels 17 are slidably connected with the outer surface of the cable 11, the outer surfaces of the four first rotating shafts 16 are fixedly connected with a first gear 18, the outer surfaces of the four first gears 18 are meshed with a second gear 19, and the inner surfaces of the four second gears 19 are fixedly connected with a second rotating shaft 20.

[0026] Both ends of the four second rotating shafts 20 are fixedly connected to angular motion detection boxes 8 , and the outer surfaces of the four angular motion detection boxes 8 are fixedly connected to a plurality of data transmission lines 9 .

[0027] One end of each of the data transmission lines 9 is fixedly connected to a controller 10 .

[0028] A front heating plate 12 is fixedly connected to the inner surface of the threading hole 6 , and a rear heating plate 13 is fixedly connected to the inner surface of the threading hole 6 .
