An adjustment assembly 3 for adjusting the cutting position is fixedly connected to the upper end of the bottom plate 1.

[0023] The following further describes the present utility model in conjunction with embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figure 1 and Figure 2 , the adjustment assembly 3 includes an installation table 35 rotatably connected inside the installation groove 12. A gear 39 is fixedly connected to one side of the installation table 35. A slide rail 310 is fixedly connected to the upper end of the bottom plate 1. A moving plate 33 is slidably connected inside the slide rail 310. A tooth block 34 is fixedly connected to one side of the moving plate 33. The tooth block 34 is meshed with the gear 39. A spring 32 is fixedly connected to the lower end of the moving plate 33. A engaging block 31 is fixedly connected to the lower end of the spring 32. The engaging block 31 is engaged with the engaging groove 11.

[0026] Specifically, when the cutting angle needs to be adjusted, the compression spring 32 is squeezed, so that the engaging block 31 is lifted upward, and the moving plate 33 is moved to slide within the slide rail 310. At this time, the tooth block 34 moves to drive the engaged gear 39 to rotate, enabling the adjustment of the cutting position. After adjusting to the required position, the applied force is cancelled. At this time, the spring 32 resumes its deformation, and the engaging block 31 is engaged and connected within the engaging groove 11 to achieve engagement, thus realizing the adjustment of the cutting position.

[0027] Embodiment 2:

[0028] Please refer to Figures 1 - 4 , a telescopic rod 36 is fixedly connected to the upper end of the mounting table 35. The upper end of the telescopic rod 36 is fixedly connected to a mounting block 37. One side of the mounting block 37 is fixedly connected to a mounting plate 38. One side of the mounting plate 38 is fixedly connected to a protective cover A4. One side of the protective cover A4 is fixedly connected to a glass window 49. One side of the mounting plate 38 is fixedly connected to a motor 41. The output end of the motor is fixedly connected to a blade 45. One side of the mounting plate 38 is snap-connected to a connecting plate 5. One side of the connecting plate 5 is fixedly connected to a protective cover B48. The protective cover B48 is rotatably connected to the blade 45. One side of the protective cover B48 is fixedly connected to a limiting plate 47. A limiting groove 46 is opened at the upper end of the limiting plate 47. One side of the protective cover B48 is rotatably connected to a fixed shaft 42. One side of the fixed shaft 42 is fixedly connected to a fixing plate 44. One side of the fixing plate 44 is fixedly connected to a brush 43.

A waste material groove 13 is opened on one side of the bottom plate 1.

[0029] Specifically, the telescopic rod 36 can adjust the cutting height. The protective cover A4 can prevent debris from splashing and scratching the operator during the cutting process. The operator can observe the cutting situation inside the protective cover A4 through the glass window 49. The protective cover B48 can protect the blade 45 and reduce the probability of the blade 45 being damaged. When it needs to be disassembled, only the snap-connected connecting plate 5 needs to be pulled out, which is simple and convenient to operate. When the brush 43 is not needed, rotate the fixing plate 44 so that the fixing plate 44 is placed in the limiting groove 46. When it is necessary to use the brush 43 to clean the blade 45, rotate the fixing plate 44 so that the brush 43 contacts the blade 45 for cleaning. Place the metal on one side of the clamping plate A24, rotate the threaded rod 22 so that the threaded rod 22 moves, driving the clamping plate B23 to move. Stop rotating when the clamping plate B23 clamps the metal, thus realizing the clamping of the metal. The waste material after cutting will fall into the waste material groove 13.
