Each fixing block 4 is provided with a card slot 41 corresponding to accommodate the end 31 of the straightening strip 3 along the length direction. The end 31 of the straightening strip 3 gradually decreases in width from top to bottom and is located in the card slot 41 of the fixing block 4, and the shape of the card slot 41 matches the shape of the end 31 of the straightening strip 3. In this embodiment, as Figure 3 shown, the cross-section of the end 31 of the straightening strip 3 is trapezoidal, and the cross-section of the card slot 41 is also trapezoidal. The depth of the card slot 41 is less than the height of the end 31 of the straightening strip 3, and the card slot 41 penetrates from the top to the bottom of the fixing block 4.
