That is, the inclination of the movable plate 2 can be realized by the sliding of the contact surfaces and the inclined contact surfaces, and then the inclination of the cutting knife is controlled.

[0030] The contact surface has two inclined surfaces with different orientations. That is, from the front view and the side view, the contact surface is inclined. For details, see Figures 6-9 , and Figure 6 and 7 are respectively schematic diagrams of two sides of the adjusting block 42, Figure 8 and 9 are respectively schematic diagrams of the inclined surfaces of the adjusting upper frame 41, Figure 9The arrow above is the inclined surface, because this inclined surface is inwardly inclined, so from Figure 8 Only a diagonal line can be seen above.

[0031] The adjusting upper frame 41 is located below the connecting part 31 of the connecting assembly 3, and the adjusting upper frame 41 is also provided with an adjusting screw 43, and the adjusting upper frame 41 can move along the direction of the adjusting screw 43 through the driving of the adjusting screw 43.

[0034] The fine adjustment assembly 4 further comprises an auxiliary cylinder 45, and the auxiliary cylinder 45 is connected with the movable plate 2 and the connecting part 31 of the connecting assembly 3 respectively, and under the action of the auxiliary cylinder 45, the contact surface of the adjusting upper frame 41 and the adjusting block 42 is in contact.

[0035] The connecting assembly 3 comprises connecting rods 32, multiple connecting rods 32 are vertically arranged on the upper top plate 1, and the movable plate 2 is sleeved on the connecting rods 32 through linear bearings 33 and can move along the direction of the connecting rods 32. Although the connecting rods 32 are vertically arranged and the movable plate 2 is sleeved on the connecting rods 32, theoretically, the movement of the movable plate 2 should be vertical, but in actual application, due to the fact that the apertures of the linear bearings 33 and the diameters of the connecting rods 32 are not completely matched, a slight inclination problem may occur, which in turn causes the cutter arranged below the movable plate 2 to be slightly inclined, so that the micro-adjusting assembly 4 is matched to realize the technical problem to be solved by the present application.

[0036] The connecting assembly 3 further comprises connecting portions 31 arranged on the lower side of the upper top plate 1, the connecting portions 31 are internally provided with guide bearings 34, the guide bearings 34 are internally provided with guide columns 35, and the lower ends of the guide columns 35 are connected to the movable plate 2.
