[0033] Working principle: After the hydraulic cylinder 1 and the connecting seat 13 are installed, they are in the horizontal direction. Subsequently, the fixing plate 14 can be installed on the surface of the connecting seat 13, and the telescopic rod 15 is stretched to its maximum length. The sliding plate 16 will drive the elastic cloth 17 to slide along the hydraulic cylinder 1, that is, the hydraulic cylinder 1, the piston rod 12, and the connecting seat 13 will all be inside the elastic cloth 17. When the vehicle body vibrates, the piston rod 12 will slide along the hydraulic cylinder 1 to achieve damping adjustment. When the vehicle is driving, there will be some splashing sand and gravel at the bottom. When these sand and gravel splash towards the hydraulic cylinder 1, they will be intercepted by the elastic cloth 17. When the sliding plate 16 drives the elastic cloth 17 to slide, the connecting rod 2 and the positioning plate 22 will also move with the sliding plate 16. Since the hydraulic cylinder 1 is inside the positioning plate 22, when the positioning plate 22 moves, it will be limited by the hydraulic cylinder 1, making the moving path of the sliding plate 16 more stable and accurate. When the sliding plate 16 drives the connecting rod 2 and the positioning plate 22 to move, the first cleaning plate 3 will also move with the positioning plate 22. When the first cleaning plate 3 moves, it will come into contact with the surface of the hydraulic cylinder 1 and clean it, reducing the dust and impurities attached to the surface of the hydraulic cylinder 1. The support plate 4 will support both sides of the elastic cloth 17. At the same time, the elastic rod 42 will be squeezed towards the surface of the elastic cloth 17 under its own elastic force, so that the elastic cloth 17 will be in a taut state under the squeezing action of the support plate 4 and the elastic rod 42, reducing the wrinkles on the surface of the elastic cloth 17 caused by deformation when it moves with the sliding plate 16. When the piston rod 12 slides along the hydraulic cylinder 1, there will be oil stains attached to its surface. When the piston rod 12 slides out of the hydraulic cylinder 1, the piston rod 12 will pass through the circular plate 52 and come into contact with the second cleaning plate 53 and be cleaned on its surface, reducing the oil stains attached to the surface of the piston rod 12. When the piston rod 12 slides along the circular plate 52, it will come into contact with the pressing plate 6. One side of the pressing plate 6 will be pushed towards the second cleaning plate 53 under the extrusion of the piston rod 12 and squeeze the second cleaning plate 53, so that the accumulated oil stains in the second cleaning plate 53 are squeezed out, reducing the oil stains accumulated in the second cleaning plate 53. At the same time, the pressing plate 6 will also scrape off the impurities attached to the surface of the piston rod 12. When the pressing plate 6 comes into contact with the piston rod 12, the circular ring 7 will also come into contact with the piston rod 12, and the circular ring 7 will increase the contact area between the pressing plate 6 and the piston rod 12.
