The carrier 324 includes a frame 3241, and the frame 3241 is triangular prism-shaped. The side of frame 3241 adjacent to spring plate 323 is a concave cylindrical curved surface. The rubber block 3242 is fixed to the frame 3241 by bolts, the rubber block 3242 has a trapezoidal longitudinal section, the rubber block 3242 is inserted into the frame 3241 so as to slide in the height direction of the frame 3241, and the rubber block 3242 is fixed to the frame 3241 by bolts. The bumper bar 3243 is semi-cylindrical, the bumper bar 3243 is pivotally attached to the top of the rubber block 3242, and a plurality of bumper bars 3243 are arranged along the length of the rubber block 3242.

The first tool bit 34 comprises a tool body 341, the tool body 341 being wedge-shaped. The fixing frame 344 is in a rectangular frustum shape, the fixing frame 344 is fixed to the lower end of the tool body 341 by bolts, and the fixing frame 344 extends in the longitudinal direction of the tool body 341. The first blade 342 is triangular prism-shaped, the longitudinal section of the first blade 342 is right-angled triangle, and the first blade 342 is bolted into the fixing frame 344. The first bolt 343 is screwed to the first blade 342 and the fixing frame 344. The backing plate 345 is a rectangular thin plate, the backing plate 345 is fixed to the inner wall of the frame 344 by bolts, and the backing plate 345 is pressed against the side wall of the first blade 342.

When the multifunctional cleaning tool is used, the first screw 313 is rotated, the first screw 313 rotates and drives the connecting plate 314 to ascend or descend, the connecting plate 314 moves and pulls the first scraper 312, the first scraper 312 rotates around a pivoting shaft of the connecting plate 314 (wherein the pivoting shaft is consistent with the length direction of the first scraper 312), and the top plate 311 rotates along with the first scraper 312, so that the inclination angles of the first scraper 312 and the top plate 311 are changed.

When the first scraper 312 rotates to pull the connecting seat 32, the first blade 33 and the first blade 34, the inclination angles of the first blade 33 and the first blade 34 are changed, thereby realizing the change of the inclination angle of the first blade 34. By rotating the first cutter head 34 to different inclination angles, when the included angle between the first cutter head 34 and the vertical direction is smaller, the first cutter head 34 can cut into the soil deeply in the vertical direction, and the plowing of the soil with a larger depth is realized. When the inclination of the first cutter head 34 is larger, the first cutter head 34 tilts outwards in the direction away from the adjusting frame 1, and the transverse spreading range of the two first cutter heads 34 is enlarged, so that the area of the ploughed land is expanded, and the ploughing efficiency of the land is conveniently improved.

When the rubber gasket is used, the second screw 321 is rotated, the second screw 321 drives the rubber gasket 322 and the spring plate 323, the spring plate 323 is made of spring steel, and the spring plate 323 deforms after being extruded. The two ends of the spring plate 323 are respectively deformed outwards and respectively push the blocking frame 31 and the first cutting board 33 to adjust the inclination angle and the opening amplitude of the blocking frame 31 and the first cutting board 33, and by adjusting the first cutting board 33 to different inclination angles and opening amplitudes, when the first cutting board 33 is expanded downwards, and the soil with a large angle can be ploughed by the two first cutting boards 33 simultaneously when the soil is ploughed, so that the ploughing efficiency is improved.

When the soil is ploughed, the first knife board 33 cuts into the soil and pushes the soil to turn over, the first knife board 33 rotates downwards under the pressure of the soil and pulls the spring board 323, the spring board 323 pulls the spring board 323 downwards, the spring board 323 generates bending deformation and downwards presses the buffer strip 3243, the buffer strip 3243 is made of rubber materials, and the buffer strip 3243 generates certain deformation after being pressed so as to relieve the pressing force. Meanwhile, the buffer strip 3243 and the rubber block 3242 are in contact through a cylindrical curved surface, and after the buffer strip 3243 and the rubber block 3242 are extruded, relative rotation occurs between the buffer strip 3243 and the rubber block 3242, so that structural damage caused by hard extrusion is avoided, and the bearing capacity and the safety in use are improved.

In use, the rubber block 3242 is raised or lowered in the height direction of the frame 3241 as needed, and after the rubber block 3242 is adjusted to a target position, the position thereof is fixed by a bolt. When the rubber block 3242 is pressed against the lower side of the spring plate 323 after rising, the lower middle position of the spring plate 323 is supported relatively strongly. In contrast, when the rubber block 3242 adjusts its position downward along the frame 3241, the pressing force of the rubber block 3242 and the spring plate 323 decreases.

A plurality of buffering strips 3243 adopt split type structure to contact with spring plate 323 respectively, avoid the extrusion force to lead to the atress too big to cause structural damage on single buffering strip 3243.

In use, the first blade 342 is slid upward or downward along the height direction of the fixing frame 344, and after the first blade 342 is adjusted to a target position, the first bolt 343 is rotated to fix the position of the first blade 342. When the first blade 342 moves, the lining plate 345 slides to a proper position, the lining plate 345 is made of rubber materials, and the lining plate 345 is pressed on the inner wall of the fixing frame 344 and the side wall of the first blade 342, so that the side wall of the first blade 342 is pressed, the first blade 342 is ensured to be stably and firmly installed, and the situation that the position of the first blade 342 deviates due to large stress when the soil is ploughed, and the normal use is influenced is avoided.

The second cutter 4 includes a rectangular first connecting plate 45, and further includes a third screw 47, and the third screw 47 is screwed on the upper portion of the first connecting plate 45. The upper end of the third screw 47 is screwed to the lower side of the base 5.

The extension bar 43 is a round bar, the extension bar 43 is threaded onto the first screw 44, and the end of the extension bar 43 is pivotally connected to the knife plate 41. The third spring 42 is sleeved on the telescopic rod 43. One end of the third spring 42 is bound to the side wall of the knife plate 41, and the other end of the third spring 42 presses the end of the first coil 44. The cutting board 41 includes a quadrangular frustum pyramid-shaped mounting plate 411. The blade 412 is rectangular and is fixed on the side wall of the mounting plate 411 by bolts; the plurality of blades 412 are arranged along the height direction of the mounting plate 411.

In use, the telescopic rod 43 is rotated along the axial direction of the first screw 44, the end of the telescopic rod 43 pulls the knife plate 41, the knife plate 41 rotates along with the telescopic rod 43, and the telescopic rod 43 rotates around the end of the adjusting plate 46. The inclination angle of the knife plate 41 changes after the rotation thereof, and the lateral distance of the two knife plates 41 changes. When the cutting blades 41 are close to each other, the lateral distance is reduced and the range of the excavated ground is reduced, but the lower end of the cutting blade 41 is rotated downward and the depth of the ground excavated by the cutting blade 41 in the longitudinal direction becomes large. When the soil is ploughed, the soil presses the cutter plate 41, the cutter plate 41 transmits the received extrusion force to the third spring 42, the third spring 42 deforms to relieve the extrusion force, meanwhile, the third spring 42 generates a reverse action force to the cutter plate 41, the two sides of the cutter plate 41 are ensured to be stressed in a balanced manner, and stable soil ploughing operation is realized.
