After the cutter body 3 is inserted into the No. 1 mounting slot 2, the mounting shell 11 is installed inside the die-cutting board 1 by being engaged. The mounting shell 11 can perform linear limiting movement for the mounting plate 12 inside. By utilizing the elastic effect of the spring 13, the spring 13 can elastically push the mounting plate 12 to move inside the mounting shell 11. The mounting plate 12 pushes the positioning plate 15 to insert into the positioning slot 5 provided inside the cutter body 3. By inserting the positioning plate 15 into the positioning slot 5, the cutter body 3 can be positioned and installed inside the No. 1 mounting slot 2.

[0025] When the cutter body 3 needs to be disassembled and replaced, since the internal parts of the No. 1 mounting groove 2 and the No. 2 mounting groove 6 are connected, the top plate 8 movably arranged inside the No. 2 mounting groove 6 can contact the bottom end part of the cutter body 3 installed inside the No. 1 mounting groove 2, and by applying a rotational force to the threaded rod 10, the top plate 8 can move toward the inside of the No. 2 mounting groove 6. After the locking plate 15 is pulled out from the inside of the locking groove 5 by pulling the pull rod 14, the top plate 8 is used to move toward the inside of the No. 2 mounting groove 6, and the top plate 8 can assist the cutter body 3 to be disassembled from the inside of the No. 1 mounting groove 2. The cutter removal step has a simple and practical structure, which effectively improves the replacement speed of the cutter and effectively improves the use efficiency of the cardboard die-cutting die.

The cutter body 3 is detachably combined and connected with the No. 1 mounting groove 2 to realize the combined connection of the die-cutting die. The cardboard can be die-cut by using the cutter body 3. The connecting plate 4 is connected and installed inside the cutter body 3. The connecting plate 4 can increase the stability of the cutter body 3 when in use. The No. 2 mounting groove 6 provides a movable space for the top plate 8 to move up and down. The support plate 9 is connected to the threaded rod 10 by threaded penetration. The support plate 9 can support the threaded rod 10. The four groups of guide columns 7 arranged inside the No. 2 mounting groove 6 can move through the inside of the top plate 8. The guide columns 7 can assist in limiting the top plate 8 to move up and down, thereby ensuring the stability of the top plate 8 when in use.

[0029] When in use, the positioning plate 15 is inserted into the positioning groove 5, so that the cutter body 3 can be positioned and installed in the No. 1 installation groove 2. When the cutter body 3 needs to be disassembled and replaced, the top plate 8 can be moved to the inside of the No. 2 installation groove 6 by applying a rotational force to the threaded rod 10. After the positioning plate 15 is pulled out from the inside of the positioning groove 5 by pulling the pull rod 14, the top plate 8 is used to move to the inside of the No. 2 installation groove 6. The top plate 8 can assist the cutter body 3 to be detached from the inside of the No. 1 installation groove 2. The cutter removal step is simple and practical, which effectively improves the replacement speed of the cutter and effectively improves the use efficiency of the cardboard die cutting die.

[0030] The cutter body 3 is detachably combined with the No. 1 mounting groove 2 to realize the combined connection of the die-cutting die. The cutter body 3 can be used to die-cut cardboard. The connecting plate 4 can increase the stability of the cutter body 3 when in use. The four groups of guide columns 7 arranged inside the No. 2 mounting groove 6 can flexibly penetrate the interior of the top plate 8. The guide columns 7 can assist the limit top plate 8 to move up and down, thereby ensuring the stability of the top plate 8 when in use.
