Fig. 2 is A-A place sectional view in Fig. 1 of the embodiment of the present invention;
Fig. 3 is the saw blade fastening device structural representation of the embodiment of the present invention.
Detailed description of the invention
With reference to Fig. 1 ~ Fig. 3, the invention provides a kind of carbon fiber guiding Linear cut means for adjusting limit of movement, comprise two parallel studs 2 being located at saw blade 1 two ends, two studs 2 are equipped with vertically the draw-in groove 21 laying saw blade 1, the middle part that the two ends of two studs 2 are equipped with nut 22, two studs 2 of clamping saw blade 1 is connected with the positive stop strip 23 parallel with saw blade 1 in the side of draw-in groove 21.
The present invention in use, saw blade 1 is placed in the draw-in groove 21 of two studs 2, and adjust the position of saw blade 1 in draw-in groove 21 by the nut 22 at studs 2 two ends, according to the thickness of carbon-fibre wire epidermis, control saw blade 1 land tip to the distance of positive stop strip 23 lower surface, make after saw blade 1 cuts to designated depth, stop due to positive stop strip 23 avoids sawing excessively dark, thus ensure that carbon fiber core is without any damage, ensure wire quality, ensure electric power netting safe running; Wherein positive stop strip 23 is preferably the key bar of 6 × 6.
As the preferred embodiment of the present invention, two studs 2 are provided with packing ring between nut 22 and saw blade 1.
As the preferred embodiment of the present invention, packing ring comprises plain washer 24 and is located at the spring washer 25 between plain washer 24 and nut 22.
