The top ends of the first guide rods 6 are welded with a connecting plate 14. On both sides of the bottom surface of the connecting plate 14, moving blocks 12 are slidably connected. The bottom of the moving block 12 is hinged with an adjusting rod 9, and the other ends of the two groups of adjusting rods 9 are respectively hinged with both sides of the top surface of the adjusting seat 7. A cutting blade 8 is fixedly installed on the bottom surface of the adjusting seat 7. The adjusting seat 7 can be adjusted through the adjusting rod 9, so as to realize the adjustment of the cutting blade 8.
[0025] In this embodiment, on both sides of the top surface of the adjusting seat 7, first springs 10 surrounding the outer circle of the first guide rod 6 are fixedly installed, and the other ends of the first springs 10 are fixedly connected with the bottom surface of the connecting plate 14. On both sides of the bottom surface of the connecting plate 14, fixing plates 17 are welded. On one side of the right fixing plate 17, a threaded rod 13 penetrating through the two groups of moving blocks 12 and the fixing plate 17 is rotatably connected. The left end of the threaded rod 13 is provided with a first bevel gear 18. On the left side of the top surface of the connecting plate 14, a rotating rod 20 penetrating through the connecting plate 14 is rotatably connected. The bottom end of the rotating rod 20 is provided with a second bevel gear 19, and the second bevel gear 19 meshes with the first bevel gear 18. A handwheel 11 is installed at the top end of the rotating rod 20. By rotating the handwheel 11, the rotating rod 20 can be driven to rotate, and then the threaded rod 13 can be driven to rotate through the second bevel gear 19 and the first bevel gear 18, so that the moving block 12 can be moved, and the adjusting seat 7 can be adjusted through the adjusting rod 9. On both sides of the bottom surface of the connecting plate 14, movable rods 15 penetrating through the workbench 1 are fixedly installed. On both sides of the top surface of the workbench 1, second springs 16 surrounding the outer circle of the movable rods 15 are fixedly installed, and the other ends of the second springs 16 are fixedly connected with the bottom surface of the connecting plate 14.
