[0026] When in use, insert the end of the knife strip into the accommodating box 1 so that the end to be coated leaks out, and then push the second wedge block 12 to slide in the through groove 9. Under the push of the second wedge block 12, the first wedge block 11 approaches the clamping piece, and the knife strip is clamped and fixed with the cooperation of the first wedge block 11 and the clamping piece.
[0027] In some embodiments, the receiving box 1 is rectangular, and two adjacent receiving boxes 1 are fixed by welding. The rectangular receiving box 1 makes it more convenient to fix the receiving box 1 by welding.
[0028] In some embodiments, in order to prevent the second wedge block 12 from retreating, the ends of the two rows of accommodating boxes 1 are fixedly connected with fixing blocks 4, both ends of the second wedge block 12 are fixedly connected with the rotating shaft 5, and the middle part of the fixing block 4 is threadedly connected with a positioning bolt 3 for limiting the rotating shaft 5. When the second wedge block 12 is adjusted, the positioning bolt 3 is rotated, and the positioning bolt 3 acts on the rotating shaft 5 to limit the second wedge block 12 and prevent it from retreating.
[0029] Specifically, the ends of the two rows of accommodating boxes 1 are fixedly connected with shaft heads 2, and the shaft heads 2 are used to be installed in cooperation with the PVD coating equipment and realize rotation so as to achieve uniform coating.
[0030] In order to balance the center of gravity during the rotation, the feed openings of two adjacent accommodating boxes 1 face opposite directions so that the blades are symmetrically distributed.
[0031] See also Figure 2 As shown, in some embodiments, the clamping member is a limiting bolt 7, which penetrates the side wall of the accommodating box 1 and is threadedly connected to the accommodating box 1. By controlling the screwing depth of the limiting bolt 7, the distance between the limiting bolt 7 and the first wedge block 11 is controlled to adapt to the positioning of blades of different thicknesses.
[0032] See also Figure 3As shown, in some embodiments, in order to ensure the clamping and positioning effect and prevent the blade from loosening, the clamping member includes a limit bolt 7, an internal threaded barrel 13, an external threaded barrel 14 and a spring 15, the internal threaded barrel 13 is fixedly connected to the accommodating box 1, the external threaded barrel 14 is threadedly connected to the internal threaded barrel 13, the limit bolt 7 penetrates the external threaded barrel 14 and is slidably connected to the external threaded barrel 14, and the spring 15 is sleeved on the outer side of one end of the limit bolt 7 located inside the accommodating box 1. Specifically, the end of the limit bolt 7 located inside the accommodating box 1 is fixedly connected with a pressing plate 10, and the spring 15 is located between the pressing plate 10 and the external threaded barrel 14.
[0033] When the pair of clamps are in use, the spring 15 compensates for the pressure to prevent the blade from loosening; by controlling the screw-in depth of the external threaded barrel 14 and the distance between the end face of the external threaded barrel 14 and the first wedge block 11, the size of the spring 15 compensating pressure is controlled.
