A second through groove 25 and a circular groove 26 are formed in the surface of the limiting tube 23. An extension rod 12 is inserted into the circular groove 26. The extension rod 12 can move in the circular groove 26. A rotating block 22 is arranged at the end of the extension rod 12. A limiting ring is arranged at the end of the rotating block 22. The limiting ring is located inside the extension rod 12. The rotating block 22 moves along with the extension rod 12, and the rotating block 22 can rotate at the end of the extension rod 12. A second spring 27 is connected to the surface of the rotating block 22. The other end of the second spring 27 is connected to the inner wall of the circular groove 26. A receiving tube 24 is fixed inside the circular groove 26. The end of the circular groove 26 is located inside the receiving tube 24. The extension rod 12 is fixed to the bottom of the inner lining 3. The extension rod 12 moves along with the inner lining 3. A first through groove 11 is formed in the surface of the extension rod 12. An arc-shaped rod 10 is inserted into the first through groove 11. The arc-shaped rod 10 can move inside the first through groove 11. A notch 9 is formed in the surface of the arc-shaped plate 8. The end of the arc-shaped rod 10 is located in the notch 9. The arc-shaped rod 10 can move in the notch 9. A U-shaped rod 32 is fixed to the end of the inner plate 2. A rectangular groove 33 is formed in the surface of the U-shaped rod 32. When the rectangular groove 33 is located in the inner plate 2, the end of the inner lining 3 is inserted into the rectangular groove 33 on the surface of the U-shaped rod 32. A rotating rod 30 is arranged at the end of the U-shaped rod 32. The rotating rod 30 can rotate at the end of the U-shaped rod 32. An elliptical block 28 is fixed to the end of the rotating rod 30. The rotating rod 30 rotates along with the elliptical block 28. The elliptical block 28 is elliptical, and the central position of the elliptical block 28 does not coincide with the central position of the rotating rod 30. When the elliptical block 28 rotates along with the rotating rod 30 and the inner lining 3 is located in the inner plate 2, the elliptical block 28 abuts against the end of the inner lining 3, stabilizing the inner lining 3 inside the inner plate 2 and causing the second spring 27 to be compressed. A cross groove 29 is formed in the surface of the elliptical block 28. By inserting a screwdriver into the cross groove 29 and rotating, the elliptical block 28 can be rotated. Limiting grooves 31 are formed in the surface of the inner plate 2. There are two groups of limiting grooves 31. When the inner lining 3 is located in the inner plate 2, the clamping ring 6 on the surface of the inner lining 3 and the first buffer strip 20 and the second buffer strip 21 on the surface of the arc-shaped plate 8 are located in the limiting grooves 31 on the surface of the inner plate 2. The first buffer strip 20 and the second buffer strip 21 are elastic and can play a buffering role. A plurality of first screwing holes 5 are formed in the surface of the arc-shaped strip 4. A plurality of second screwing holes 35 are formed in the surface of the inner plate 2. The positions of the second screwing holes 35 correspond to the positions of the first screwing holes 5. The inner lining 3 is elastic. Since the end of the inner plate 2 is inclined, when the arc-shaped strip 4 at the end of the inner lining 3 is screwed to the end of the inner plate 2 through a screw, the inner lining 3 is bent. After the elliptical block 28 rotates, it abuts against the end of the inner lining 3, pre-stabilizing the inner lining 3 inside the inner plate 2, facilitating the fixing of the inner lining 3 with a screw. Since the inner lining 3 is flexible,When screwed into the first screw hole 5 on the surface of the arc-shaped strip 4 and the second screw hole 35 on the surface of the inner plate 2 through the screw, the inner lining 3 is distorted. The inner lining 3 is fixed inside the inner plate 2, and the inner lining 3 exerts a reverse force due to the bending to prevent the screw from loosening.

[0035] Multiple groups of water troughs 13 are provided on the surface of the inner lining 3. Multiple groups of push plates 14 are inserted on the surface of the inner lining 3. The push plates 14 can telescopically move on the surface of the inner lining 3. A moving plate 16 is inserted at the bottom of the inner lining 3. The moving plate 16 can move up and down inside the inner lining 3. The end of the moving plate 16 is connected to the push plate 14. The ends of multiple groups of push plates 14 are connected to the moving plate 16. The push plates 14 move up and down with the moving plate 16. An elastic plate 15 is fixed on the surface of the moving plate 16. The elastic plate 15 has elasticity. An arc-shaped strip 4 is fixed at the end of the inner lining 3. Multiple groups of first screw holes 5 are provided on the surface of the arc-shaped strip 4. A plugging rod 36 is fixed at the end of the inner lining 3. A plugging hole 34 is provided at the end of the inner plate 2. The plugging rod 36 moves and rotates with the inner lining 3. The plugging rod 36 can be plugged into the plugging hole 34. And a damping pad is provided on the surface of the plugging rod 36. When the plugging rod 36 is plugged into the plugging hole 34, the plugging rod 36 can be stable in the plugging hole 34 to stabilize the position of the inner lining 3.

[0036] The bottom of the moving plate 16 is connected to a first spring 18. The other end of the first spring 18 is connected to the surface of an arc-shaped plate 8. A first buffer strip 20 is fixed on the surface of the arc-shaped plate 8. The surface of the arc-shaped plate 8 is connected to a clamping ring 6. A second buffer strip 21 is fixed on the surface of the clamping ring 6. An arc-shaped rod 10 is fixed on the surface of the moving plate 16. The end of the arc-shaped rod 10 moves with the moving plate 16. The moving plate 16 will drive the push plate 14 to vibrate, causing the push plate 14 to reciprocate. And first buffer strip 20 and second buffer strip 21 are provided on the surfaces of the arc-shaped plate 8 and the clamping ring 6. When the inner lining 3 is located inside the inner plate 2, a U-shaped rod 32 is inserted into the inside of the clamping ring 6.

[0037] The extension rod 12 can move in the circular groove 26, and the rotating block 22 at the end of the extension rod 12 can rotate on the surface of the extension rod 12. Under the elastic force of the second spring 27, the extension rod 12 pops out, enabling the inner liner 3 to be taken out. When the extension rod 12 rotates, the inner liner 3 rotates along with the extension rod 12, facilitating the cleaning of the surface of the inner liner 3. Moreover, a water trough 13 is provided on the surface of the inner liner 3, which enables the accumulated water on the surface of the inner liner 3 to flow away quickly. The pushing plate 14 on the surface of the inner liner 3 can telescopically move on the surface of the inner liner 3. When the pushing plate 14 moves, it will push and loosen the soil adhered to the surface of the inner liner 3. The ends of multiple groups of pushing plates 14 are connected to the moving plate 16, and a first spring 18 is provided at the end of the moving plate 16. During the vehicle's driving process, the moving plate 16 will drive the pushing plate 14 to vibrate, causing the pushing plate 14 to reciprocate. Additionally, a first buffer strip 20 and a second buffer strip 21 are provided on the surfaces of the arc-shaped plate 8 and the clamping ring 6. When the inner liner 3 is located inside the inner plate 2, the U-shaped rod 32 is inserted into the inside of the clamping ring 6, and the end of the inner liner 3 is inserted into the rectangular groove 33 on the surface of the U-shaped rod 32, stabilizing the inner liner 3 inside the inner plate 2. Moreover, the elliptical block 28 can rotate. After the elliptical block 28 rotates, it abuts against the end of the inner liner 3, pre-stabilizing the inner liner 3 inside the inner plate 2, facilitating the use of a screw to fix the inner liner 3. Since the inner liner 3 is flexible, when the screw is screwed into the first screw hole 5 on the surface of the arc-shaped strip 4 and the second screw hole 35 on the surface of the inner plate 2, the inner liner 3 is distorted, and the inner liner 3 is fixed inside the inner plate 2. Moreover, due to the bending of the inner liner 3, a reverse force is exerted to prevent the screw from loosening. When cleaning the inner liner 3, pull the arc-shaped rod 10. The arc-shaped rod 10 moves in the first through groove 11 and the notch 9, driving the moving plate 16 and the pushing plate 14 to move, facilitating the cleaning of the surface of the inner liner 3.
