A pressing plate 48 is arranged on one side of the connecting block 47 away from the fixed rod 41. The pressing plate 48 is in contact with the outer wall of the oil filter body 2 through the pressing plate 48. When the oil filter body 2 vibrates, the vibration is transmitted to the sliding sleeve 42 through the pressing plate 48 and the movable rod 46, so that the sliding sleeve 42 moves in the fixed rod 41, and the oil filter body 2 is damped under the action of the damping spring 43.

[0025] A screw 471 is provided inside the connecting block 47, and the movable rod 46 is rotatably arranged on the connecting block 47, so that the movable rod 46 can rotate around the screw 471 to prevent it from being broken due to long-term pressure. A protective pad 481 is provided on the side of the clamping plate 48 close to the oil filter body 2. The protective pad 481 is close to the oil filter body 2 to prevent the clamping plate 48 from rubbing against the surface of the oil filter body 2 for a long time and causing damage.

[0026] Both ends of the clamping plate 48 are connected with sliders 5, which are slidably arranged inside the slide groove 6. The slide groove 6 is arranged on the side of the support plate 3 close to the oil filter body 2.
