It should be noted here that the connecting column 27 is relatively long. At this time, the gear accommodating hole 30 may not be concentric with the adjusting gear 36. The third hand-tightening screw 26 can be rotated by hand. When the gear accommodating hole 30 is concentric with the adjusting gear 36, continue to push the gear locking plate 7, and at the same time, pull the two rings 35 outward with both hands so that the two locking rods 32 will not interfere with the adjusting gear 36. After the gear locking plate 7 is fitted with the right side wall of the crease box 1, the two rings 35 are loosened. Under the action of the spring 34, the locking rods 32 approach each other and are inserted into the tooth spacing of the adjusting gear 36 to lock the adjusting gear 36. At this time, the adjusting gear 36 cannot rotate.

[0037] Then place the first fixing plate 8 on the top of the crease box 1, loosen the first hand screw 14 after adjusting the position, adjust the height of the horizontal adjustment plate 4 with one hand, and move one of the positioning blocks 5 with the other hand. When the upper limit end 19 of the positioning block 5 contacts the top of the dotted line knife 2, tighten the first hand screw 14, and then fine-tune the distance between the two positioning blocks 5 so that the positioning block 5 contacts the blade of the dotted line knife 2, and then tighten the two second hand screws 18. At this time, the circumferential position and axial position of the old dotted line knife 2 are recorded. Then pull the two rings 35 at the same time, drag the gear locking plate 7 outward to remove it. It should be noted that the first seat body 3 and the second seat body 6 are left in place. Then remove the old dotted line knife and install the new dotted line knife. When adjusting the position of the new dotted line knife, first use the gear locking plate 7 to lock the adjustment gear 36. Then accurately adjust the position of the two new dotted line knives 2 according to the position of the two positioning blocks 5.
