A fixing sleeve 4 is fixedly connected to the top of the two elastic sheets 3, and the fixing sleeve 4 is used to fix other components.

[0033] refer to Figure 2 、 Figure 3 Two slide holes 5 are defined in the center of the fixed sleeve 4. These holes extend through the sleeve and are used to adjust the size of the central opening of the support ring 2. Two through-holes 6 are defined in the center of the front side of the fixed sleeve 4, connected to the slide holes 5. The outer portion of the screw rod 8 is rotatably connected to the inner wall of the through-hole 6. Two limiting rings 7 are fixedly connected to the front side of the fixed sleeve 4. The outer portion of the screw rod 8 is rotatably connected to the inner wall of the limiting ring 7. The limiting ring 7 is fixed to the front side of the fixed sleeve 4, limiting the position of the screw rod 8 and ensuring its stable rotation.

[0034] Two nuts 9 are threadedly connected to the outer ends of the screw rod 8. The nuts 9 are threadedly connected to the outer ends of the screw rod 8 and are used to fix the position of the screw rod 8. Two fixing plates 10 are fixedly connected to the front top of the support ring 2. The outer parts of the fixing plates 10 are slidably connected to the inner wall of the sliding hole 5. The outer parts of the fixing plates 10 are provided with fixing teeth 11. The fixing plates 10 cooperate with the elastic plates 3 to adjust the size of the support ring opening. The outer parts of the fixing teeth 11 are slidably connected to the inner wall of the sliding hole 5. The outer parts of the screw rod 8 are engaged with the outer parts of the fixing teeth 11. The fixing teeth 11 slide within the sliding hole 5 when the screw rod 8 rotates, tightly wrapping the outer part of the oil rail tube and adjusting the size of the middle ring opening of the support ring 2.

[0035] refer to Figure 1 、 Figure 4 . The outside of the left support ring 2 is fixedly connected to a limiting sleeve 12. The inner wall of the limiting sleeve 12 is provided with a limiting component for limiting the position of the two support rings 2. The limiting sleeve 12 slides in the positioning sleeve 18 and cooperates with the limiting component to adjust the distance between the two support blocks 1. The limiting component includes a rack 13, which is in the shape of a long strip and has teeth. The outside of the rack 13 is fixedly connected to the inner wall of the limiting sleeve 12. The end of the rack 13 away from the limiting sleeve 12 is fixedly connected to the limiting block 14. The outside of the limiting block 14 is slidably connected to the inner wall of the limiting sleeve 2 15. The limiting block 14 limits the movement of the rack 13. The outside of the left support ring 2 is fixedly connected to the limiting sleeve 2 15. The limiting sleeve 2 15 is the same as the limiting sleeve 12. The inside of the limiting sleeve 2 15 is fixedly connected to a rack 2 16. The rack 2 16 is in the shape of a long strip and has teeth.

[0036] The side of rack 2 (16) away from limiting sleeve 2 (15) is fixedly connected to limiting block 2 (17), which limits the movement of rack 2 (16). A positioning sleeve (18) is slidably connected to the outside of limiting sleeve 12, and the outside of limiting sleeve 2 (15) is slidably connected to the inner wall of positioning sleeve 18. Positioning sleeve 18 limits the sliding distance between limiting sleeve 12 and limiting sleeve 2 (15), thereby adjusting the distance between the two support blocks (1).

[0037] A positioning shaft 19 is fixedly connected to the middle of the positioning sleeve 18. The outer portion of the positioning shaft 19 is rotatably connected to an auxiliary gear 20. The positioning shaft 19 provides support and a rotation axis for the driving gear 20. The bottom teeth of rack 13 are meshed with the outer teeth of driving gear 20, and driving gear 20 drives rack 13 to slide. The outer portion of rack 13 is slidably connected to the inner wall of limit sleeve 2 15. The outer portion of limit block 14 is engaged with the outer portion of driving gear 20. The top teeth of rack 2 16 are meshed with the outer teeth of driving gear 20. The outer portion of rack 2 16 is slidably connected to the inner wall of limit sleeve 1 12. The outer teeth of driving gear 20 mesh with the bottom teeth of rack 1 13 and the top teeth of rack 2 16. When rack 1 13 slides, driving gear 20 rotates, pushing rack 2 16 to slide in the opposite direction of meshing with rack 1 13, thereby adjusting the distance between the two support blocks 1.

[0038] The exterior of the second limit block 17 engages with the exterior of the driving gear 20 and is slidably connected to the inner wall of the second limit sleeve 15. The second limit block 17 and the first limit block 14 contact the exterior of the driving gear 20, thereby limiting the sliding distance between the first limit sleeve 12 and the second limit sleeve 15. The exterior of the driving gear 20 is rotatably connected to the inner wall of the positioning sleeve 18. A mounting hole 21 is provided in the middle of the support block 1 for mounting and securing the oil rail bracket.

[0039] Working Principle: During use, the two support blocks 1 are pulled through the length of the oil rail tube, allowing the retaining sleeves 12 and 15, respectively fixed to the support blocks 1, to slide within the positioning sleeve 18. This allows the rack 13, protruding from the center of the retaining sleeve 12, to slide and mesh with the driving gear 20. The sliding of rack 13 then drives the driving gear 20 to rotate. After the driving gear 20 rotates, the teeth of the driving gear 20 push the rack 21 on the other side of the core to mesh and slide in the opposite direction of rack 13. This allows rack 13 and rack 216 to mesh and expand in opposite directions outside the driving gear 20. This adjusts the spacing between the two support blocks 1 to achieve the optimal position for securing the oil rail, adapting to the spatial layout of different vehicle models and ensuring precise docking of the oil rail with various engine components. The oil rail bracket is then installed and secured through the mounting holes 21.

[0040] After the distance between the two support blocks 1 is adjusted, the oil rail pipe is placed in the support ring 2, and then the fixing piece 10 fixed on the top of the support ring 2 is inserted into the sliding hole 5. The screw rod 8 is rotated by holding the nut 9, so that the external thread of the screw rod 8 engages the fixing teeth 11, driving the fixing teeth 11 to slide in the sliding hole 5, thereby tightly wrapping the outside of the oil rail pipe and adjusting the size of the middle circle of the support ring 2 according to the diameter of the oil rail pipe, so that the oil rail bracket can be compatible with oil pipes of various specifications.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
