[0029] A right cantilever rod 62 capable of swinging open and extending the support length is hingedly installed on one side of the right auxiliary bracket 6, and a third support column 63 and a fourth support column 64 for horizontally supporting the right cantilever rod 62 are arranged on the side wall of the right auxiliary bracket 6, and the third support column 63 and the fourth support column 64 are respectively located on both sides of the hinge between the right cantilever rod 62 and the right auxiliary bracket 6. A third positioning groove 621 and a fourth positioning groove 622 for respectively engaging with the third support column 63 and the fourth support column 64 are arranged at both ends of the right cantilever rod 62, and the third positioning groove 621 and the fourth positioning groove 622 are located on the upper and lower sides of the right cantilever rod 62. The end of the right cantilever rod 62 is provided with a second stopper 623 for preventing the die-cutting knife group 40 from falling off. The right cantilever rod 62 and the right guide wheel 61 are respectively located on both sides of the right auxiliary bracket 6, wherein the top of the right guide wheel 61 protrudes from the upper end surface of the right auxiliary bracket 6. After the right cantilever rod 62 is turned over and extended out of the right auxiliary bracket 6, the upper end surface of the right cantilever rod 62 is flush with the upper end surface of the right auxiliary bracket 6. The upper end surface of the right cantilever rod 62 is installed with a second thermal insulation pad 65, and the second thermal insulation pad 65 is flush with the upper end surface of the right auxiliary bracket 6.

Specifically: by loosening the knob lock 401 and pulling the handle 400 of the die-cutting knife group 40, the die-cutting knife group 40 is pulled out of the die-cutting mechanism 4, and is pulled out of the die-cutting mechanism 4 along the left auxiliary bracket 5 and the right auxiliary bracket 6, and the left guide wheel 51 and the right guide wheel 61 located on the left auxiliary bracket 5 and the right auxiliary bracket 6 can greatly reduce the friction of pushing and pulling the die-cutting knife group 40, so that the die-cutting knife group 40 can slide quickly. In addition, when the die-cutting knife set 40 is large in size, the left cantilever rod 52 and the right cantilever rod 62 are first flipped from the inside of the left auxiliary bracket 5 and the right auxiliary bracket 6 to the outside, and after flipping, the first thermal insulation pad 55, the third thermal insulation pad 56, the second thermal insulation pad 66 and the fourth thermal insulation pad 65 are all kept horizontally consistent, so that when the die-cutting knife set 40 is pulled out of the die-cutting mechanism 4, the die-cutting knife set 40 can slide along the left auxiliary bracket 5 and the right auxiliary bracket 6 to the left cantilever rod 52 and the left cantilever rod 62, thereby achieving stable support for the die-cutting knife set 40. Of course, when installing a new die-cutting knife set 40, the die-cutting knife set 40 is placed on the left auxiliary bracket 5 and the right auxiliary bracket 6, and the left cantilever rod 52 and the right cantilever rod 62 are opened according to the need, and then the die-cutting knife set 40 is pushed into the die-cutting mechanism 4, and the die-cutting knife set 40 is locked by the knob lock 401.
