The tooth peaks (12) and the tooth troughs (13) on the fixed jaw plate (5) and the movable jaw plate (4) are arranged oppositely and intersectedly. The tooth troughs (13) have holes (14) perforated through the base boards (11). The holes (14) are arranged in columns along a direction of a length of the tooth peak (12) on the base board (11) opposite to the holes (14). |
