[0032] Furthermore, if Figure 4 As shown, the pressing plate 4 of this embodiment is detachably connected with fixing strips 41 on two opposite sides. The detachable connection here can be fixed by screws or by snap-fitting. A through groove is provided at one end where the fixing strip 41 is connected to the pressing plate 4 and forms a clamping space for fixing the cutting die 5 with the pressing plate 4. The cutting die 5 is embedded in the through groove, and the fixing strip 41 is tightened to fix the cutting die 5.

[0033] Alternatively, if Figure 5As shown, a plurality of laser positioning devices are also provided on the side of the bracket 1 for positioning the workpiece on the die-cutting board 6, so that the lifting and lowering of the knife die 5 can be accurately controlled to accurately cut the workpiece, wherein the laser positioning device includes a moving component 9 and a laser positioning light 94, and the moving component 9 is movably connected to the bracket 1 for adjusting the position of the laser positioning light 94, and the laser positioning light 94 is fixedly connected to the moving component 9 for positioning the product on the die-cutting board 6, and the moving component 9 is used to adjust the position of the laser positioning light 94, and the structure of the moving component 9 can be to drive the laser positioning light 94 to move by a motor and a screw rod 93, or to adjust the position of the laser positioning light 94 by the cooperation of a slide rail and a slider, which will not be elaborated here.

[0034] In some possible embodiments, the moving component 9 includes two mounting blocks 91 disposed above the die-cutting plate 6, a plurality of slide rods 92 that are parallel to each other and fixedly connected to the mounting blocks 91 at both ends, a screw rod 93 that is parallel to the slide rod 92 and movably connected to the mounting blocks 91 at both ends, and a slider, wherein the slider is slidably connected to the slide rod 92, and the slider is threadedly connected to the screw rod 93 so that the slider moves along the length direction of the screw rod 93, the laser positioning light 94 is fixedly connected to the slider, and a knob 95 that is fixedly connected to one end of the screw rod 93 for facilitating the rotation of the screw rod 93, and rotating the knob 95 drives the screw rod 93 to rotate, thereby moving the slider to adjust the position of the laser positioning light 94.
