[0045] As shown in the drawings, Figure 9 As shown, the fifth threaded hole 425 is provided with a tight handle 46, and the end of the tight handle 46 is tightly connected with the cutter wheel shaft 43, so that the assembly of the cutter wheel shaft 43 can be controlled by adjusting the tight handle 46, and the up and down movement of the cutter wheel shaft 43 is facilitated to adjust the up and down position of the cutter wheel 44, and the decorative plate with different thicknesses can be adapted.

[0046] As shown in the drawings, Figure 8 As shown, the cutter wheel mounting member 42 is provided with a second threaded hole 422 matched with the through hole 413 and a third threaded hole 423 matched with the waist-shaped hole 414.

[0047] As shown in the drawings, Figure 6 As shown, after the second threaded hole 422 is connected with the through hole 413 by a screw, the right side part of the cutter wheel mounting member 42 is fixed relative to the sliding member 41, and at this time, the screw connecting the third threaded hole 423 and the waist-shaped hole 414 is rotated to adjust the position of the left side part of the cutter wheel mounting member 42, so that the cutter wheel mounting member 42 can be rotated by a certain angle with the center axis of the through hole 413 as the rotating shaft, and then the direction of the cutter wheel at the bottom 44 of the cutter wheel mounting member 42 is adjusted to control the straightness of the cutter wheel cutting, so that the cut surface is smoother.

[0048] As shown in the drawings, Figure 7 , Figure 8 and Figure 9 As shown, the connecting part 412 is further provided with an adjusting part 415 below the waist-shaped hole 414, and the cutter wheel mounting member 42 is provided with a fourth threaded hole 424, and the fourth threaded hole 424 is provided with a second adjusting screw 45 tightly connected with the adjusting part 415. By rotating the second adjusting screw 45 tightly connected with the adjusting part 415, the position of the left side of the cutter wheel mounting member 42 can be adjusted more subtly, and then the direction of the cutter wheel 44 can be adjusted more subtly. In addition, the adjusting part 415 can also support the cutter wheel mounting member 42.

[0049] As shown in the drawings, Figure 6As shown, the cutter wheel assembly 40 is provided with a cutter wheel buffer assembly 50. The cutter wheel buffer assembly 50 comprises a connecting piece 51 fixedly connected with the cutter wheel assembly 40, the connecting piece 51 is connected with a screw rod 53 through a nut 52, and the bottom of the screw rod 53 is provided with a buffer elastic piece 54. When the cutter wheel 44 is cutting, the up-and-down position of the buffer elastic piece 54 can be adjusted by adjusting the nut 52, so that the lowest point of the buffer elastic piece 54 is lower than the lowest point of the cutter wheel 44. When the cutter wheel 44 slides on the decorative plate 60, the buffer elastic piece 54 will elastically deform and will not affect the sliding of the cutter wheel, and when the cutter wheel 44 slides to the end on the decorative plate 60 and is about to be out of contact with the decorative plate 60, the buffer elastic piece 54 will restore to the original state, first contacts the ground on which the decorative plate is placed, and plays a buffering role, reduces the knocking of the cutter wheel with the ground, and protects the cutter wheel.
