[0027] Referring to Figure 2 and Figure 4 , one side of the installation block 6 close to the receiving groove 5 contacts the inner wall of the receiving groove 5. The bottom of the installation block 6 passes through the receiving groove 5 and extends to the outside of the receiving groove 5 and is fixedly connected to the cutting knife block 4.

[0028] Adopting the above scheme: By arranging the installation block 6, the cutting knife block can be installed and fixed, which is convenient for the user to use the cutting knife block.

[0029] Referring to Figure 4 and Figure 5 , the limiting device 8 includes a limiting block 801. The bottom of the limiting block 801 contacts the limiting groove 7. The top of the limiting block 801 passes through the limiting groove 7 and extends to the inner cavity of the receiving groove 5. A limiting column 802 is arranged at the top of the limiting block 801. A limiting spring 803 is sleeved on the surface of the limiting column 802.

[0030] Adopting the above scheme: By arranging the limiting device 8, the installation block 6 can be fixed and limited, which is convenient for the user to use the installation block 6.

[0031] Referring to Figure 5 , the control device 10 includes a control board 1001. A control rack 1002 is arranged at the bottom of the control board 1001. A control gear 1003 is arranged on the right side of the control rack 1002. A control column 1004 is arranged on the front side of the control gear 1003. A control switch 1005 is arranged on the front side of the control column 1004.

[0032] Adopting the above scheme: By arranging the control device 10, the limiting device 8 can be controlled, which is convenient for the user to use the limiting device 8.

[0033] Referring to Figure 4 and Figure 5, on both sides of the top inner wall of the control groove 9, first through holes 11 for cooperating with the limiting device 8 are provided, and on one side of the top inner wall of the control groove 9 close to the control rack 1002, a second through hole 12 for cooperating with the control rack 1002 is provided.

[0034] With the above solution: By providing the first through hole 11 and the second through hole 12, the limiting post 802 and the control rack 1002 can be limited, facilitating the user to use the limiting post 802 and the control rack 1002.

[0035] Reference Figure 4 and Figure 5 , one side of the limiting block 801 close to the inner wall of the control groove 9 is in contact with the inner wall of the control groove 9. The bottom of the limiting post 802 is fixedly connected to the limiting block 801. The top of the limiting post 802 passes through the first through hole 11 and extends to the outside of the pressing block 3 and is fixedly connected to the control board 1001. The top and bottom of the limiting spring 803 are respectively fixedly connected to the limiting block 801 and the inner wall of the control groove 9.

[0036] With the above solution: By providing the limiting block 801, the mounting block 6 can be fixed and limited. By providing the limiting post 802, the limiting block 801 can be driven to rise and fall. By providing the limiting spring 803, the limiting block 801 can be reset.

[0037] Reference Figure 4 and Figure 5 , the top of the control rack 1002 is fixedly connected to the control board 1001. The bottom of the control rack 1002 passes through the second through hole 12 and extends to the inner cavity of the control groove 9. The left side of the control gear 1003 meshes with the control rack 1002. The rear side of the control gear 1003 is rotationally connected to the inner wall of the control groove 9 through a rotating shaft. The rear side of the control column 1004 is fixedly connected to the control gear 1003. The front side of the control column 1004 penetrates through the control groove 9 and extends to the outside of the pressing block 3 and is fixedly connected to the control switch 1005.

[0038] With the above solution: By providing the control board 1001, the limiting post 802 can be driven to rise and fall. By providing the control rack 1002, the control board 1001 can be driven to rise and fall. By providing the control gear 1003, the control rack 1002 can be driven to rise and fall. By providing the control switch 1005 and the control column 1004, the control gear 1003 can be driven to rotate.

[0039] When it is necessary to disassemble the cutting knife block 4, rotate the control switch 1005 to drive the control column 1004 and the control gear 1003 to rotate synchronously. The control gear 1003 drives the control rack 1002 to rise. The control rack 1002 drives the control plate 1001 and the limit column 802 to rise synchronously and squeezes the limit spring 803. The limit column 802 drives the limit block 801 to rise, so that the limit block 801 disengages from the inner cavity of the limit groove 7. At the same time, when the limit block 801 rises to the inner cavity of the control groove 9, the limit block 801 no longer contacts the mounting block 6. Take out the mounting block 6, release the control switch 1005, and the force released after the limit spring 803 is squeezed pushes the limit block 801 to descend. The limit block 801 drives the limit column 802 and the control plate 1001 to descend synchronously. The control plate 1001 drives the control rack 1002 to descend. The control rack 1002 drives the control gear 1003 to rotate in the reverse direction. The control gear 1003 drives the control column 1004 and the control switch 1005 to rotate in the reverse direction and reset to complete the disassembly.

[0040] In summary, for the metal cutting device based on a screwdriver, by setting the cooperation of the mounting block 6, the limiting device 8 and the control device 10, it solves the problem that in the existing metal cutting devices, the cutting knives used to process the raw materials of the screwdriver are mostly fixed to the cutting device by bolts or welding. After long-term use, the cutting knives will be severely worn or damaged. When it is necessary to repair and replace the cutting knives, the replacement is rather cumbersome, which affects the use efficiency of the cutting device.
