[0029] Reference Figure 1-4As shown, the present embodiment discloses that the fixing assembly 2 includes a fixing block 21, one side of the fixing block 21 is threadedly connected with a first bolt 22, one side of the first bolt 22 is rotatably connected with a pressing plate 23, the pressing plate 23 abuts against the cutter 4, one side of the pressing plate 23 is fixedly connected with a fixing column 25, one side of the fixing column 25 is clamped with a through hole on the surface of the cutter 4. When the rotary tiller 1 is used, a plurality of cutters 4 are welded and fixed on the surface of the rotary tiller blade, and then the rotary tiller 1 is fixed to the rotary tiller for use. When replacing the tool 4 with deformation on the surface of the cutter disc 1, the first bolt 22 can be rotated to make the first bolt 22 drive the extrusion plate 23 and the fixing column 25 to separate from the tool 4, and then the deformed tool 4 is taken out and replaced, and then the new tool 4 is placed inside the fixing block 21, and the first bolt 22 is rotated to make the extrusion plate 23 fix the tool 4, and the fixing column 25 is engaged with the tool 4, so as to quickly complete the replacement and fixation of the tool 4 after deformation. By using the fixing component 2, the tool 4 that is deformed by force can be quickly replaced, so that the tool 4 with the changed angle can be quickly returned to its original position and fixed, so that the tool 4 on the cutter disc 1 is easier to use, thereby improving the use effect of the cutter disc 1.

[0030] Reference Figure 1-4 As shown, the present embodiment discloses that a plurality of grooves 24 are provided on the surface of the cutter disc 1, and the size of the fixing column 25 is adapted to the size of the groove 24. When the fixing column 25 passes through the through hole of the cutter 4, the fixing column 25 will reach the inside of the groove 24 on the surface of the cutter disc 1 to clamp the fixing column 25 and the cutter disc 1 together, thereby improving the fixing effect of the fixing column 25 on the cutter 4. A rubber pad 26 is fixedly connected to one side of the extrusion plate 23, and the size of the rubber pad 26 is adapted to the size of the extrusion plate 23. By using the rubber pad 26, the friction between the extrusion plate 23 and the cutter 4 is improved, thereby improving the use effect of the extrusion plate 23. A plurality of anti-sliding blocks 27 are fixedly connected to one side of the first bolt 22, and the plurality of anti-sliding blocks 27 are arranged equidistantly on one side of the first bolt 22.

When the fixing block 21 of the fixing component 2 is damaged and deformed, the second bolt 32 can be rotated to disengage the second bolt 32 from the thread groove 31 and the connecting plate 33 on one side of the cutter disc 1, and then the damaged and deformed fixing block 21 is replaced, and then the connecting plate 33 on one side of the new fixing plate is placed on the cutter disc 1, and then the second bolt 32 is rotated to fix the connecting plate 33 and the fixing block 21. By using the replacement component 3, the fixing component 2 can be quickly replaced and used, thereby improving the use effect of the fixing component 2.

[0032] Reference Figure 1-4 As shown, the present embodiment discloses that a positioning block 34 is fixedly connected to one side of the cutter disc 1, and the size of the positioning block 34 is adapted to the size of the connecting plate 33. By using the positioning block 34, the position of the connecting plate 33 on the cutter disc 1 is quickly fixed, and then the subsequent fixing of the connecting plate 33 is facilitated. A gasket 35 is abutted on one side of the second bolt 32, and one side of the gasket 35 is abutted on the connecting plate 33. By using the gasket 35, the contact area between the second bolt 32 and the connecting plate 33 is increased, so that the fixing effect of the second bolt 32 can be improved.

[0033] Working principle: When the rotary tiller 1 is used, several cutters 4 will be welded and fixed on the surface of the rotary tiller blade, and then the rotary tiller 1 will be fixed to the rotary tiller for use. When replacing the cutter 4 with deformation on the surface of the cutter 1, the first bolt 22 with the anti-sliding block 27 can be rotated so that the first bolt 22 drives the extrusion plate 23 and the fixing column 25 to separate from the cutter 4, and then the deformed cutter 4 is taken out and replaced, and then the new cutter 4 is placed inside the fixing block 21, and the first bolt 22 is rotated so that the extrusion plate 23 with the rubber pad 26 fixes the cutter 4. At this time, the moving trajectory of the extrusion plate 23 is limited by using the limit rod 28, and the fixing column 25 is engaged with the cutter 4 to quickly complete the replacement and fixation of the cutter 4 after deformation. By using the fixing assembly 2, the cutter 4 that is deformed by force can be quickly replaced, so that the cutter 4 with the changed angle can be quickly returned to its original position and fixed, so that the cutter 4 on the cutter 1 is easier to use, thereby improving the use effect of the cutter 1.

[0034] When the fixing block 21 of the fixing component 2 is damaged and deformed, the second bolt 32 can be rotated to disengage the second bolt 32 from the threaded groove 31 and the connecting plate 33 on one side of the cutter disc 1, and then the damaged and deformed fixing block 21 can be replaced. Then, the connecting plate 33 on one side of the new fixing plate is placed on the cutter disc 1 with the positioning block 34, and then the second bolt 32 is rotated to fix the connecting plate 33 and the fixing block 21. By using the replacement component 3, the fixing component 2 can be quickly replaced and used, thereby improving the use effect of the fixing component 2.
