[0025] Specifically, the base 1 serves as the basic support component of the entire cleaner, providing a stable mounting platform for other components, ensuring that the cleaner remains stable during use and is not easily shaken or tipped over. The upper surface of the base 1 is fixedly connected with a storage bin 2, which is used to store various liquids required during cleaning and detection, such as cleaning fluid, for easy access by the operator at any time. The outer wall of the storage bin 2 is fixedly connected with a support plate 8, which serves to connect and support other components. It connects the storage bin 2 with subsequent structures and provides stable support for components mounted above it, ensuring the stability of these components during operation. The upper surface of the base 1 is provided with a support assembly, which includes a support rod 6 fixedly connected at one end to the upper surface of the base 1 and at the other end to the lower surface of the support plate 8. It is mainly used to enhance the stability of the support plate 8 and prevent it from tilting or shaking due to uneven stress, thereby affecting the normal operation of the entire cleaner. The inside of the base 1 is fixedly connected with a fixed plate 21, which provides guidance and support for the sliding of a sliding plate 22, ensuring that the sliding plate 22 can slide smoothly in the predetermined direction and remain stable during sliding without deviation. The inside of the base 1 is slidingly connected with the sliding plate 22, which can slide along a specific direction inside the base 1. It adjusts the position of components such as glass tubes 5 by extruding a connecting block 23 to adapt to the fixing needs of glass tubes of different sizes. The outer wall of the sliding plate 22 is fixedly connected with the connecting block 23, which serves to connect the sliding plate 22 and a connecting plate 11. It transmits the movement of the sliding plate 22 to the connecting plate 11, allowing the connecting plate 11 to move with the sliding plate 22. The outer wall of the connecting block 23 is slidingly connected inside the base 1, which ensures that the connecting block 23 can slide smoothly. The side of the connecting block 23 away from the base 1 is fixedly connected with the connecting plate 11, which is used to connect multiple components. It connects the sliding block 14 and the limiting ring 25 above it, allowing these components to work together and move as a whole under the drive of the sliding plate 22, achieving clamping of glass tubes 5 of different sizes. The side of the connecting plate 11 close to the base 1 is fixedly connected with the sliding block 14, the outer wall of which is slidingly connected with a slide rail 4 fixedly connected to the outer wall of the base 1. The cooperation of the sliding block 14 and the slide rail 4 further improves the smoothness and stability of the sliding of the connecting plate 11, making the movement of the connecting plate 11 more stable and less likely to jam or shake, ensuring the accuracy of the entire adjustment process. The side of the connecting plate 11 away from the storage bin 2 is fixedly connected with the limiting ring 25, the inside of which is slidingly connected with a guide rod 20, the outer wall of which is provided with a spring 26. The outer wall of the limiting ring 25 is slidingly connected with a limiting block 24, the outer wall of which is fixedly connected to the outer wall of the base 1. The guide rod 20 provides a guiding effect for the movement of the limiting ring 25, allowing it to slide only in the direction of the guide rod 20.Spring 26 serves a resetting function. When the connecting plate 11 is moved by external force, spring 26 provides a certain elastic force to automatically reset it within a certain range. Limiting block 24 restricts the sliding range of limiting ring 25, preventing the connecting plate 11 from moving due to pressure from the surface of glass tube 5, thus ensuring accurate clamping. Spring 18 is fixedly connected inside the sliding plate 22, with one end fixed inside the fixing plate 21 and the other end connected to the squeezing plate 19. When the glass tube 5 is placed on the cleaner, the squeezing plate 19, under the elastic force of spring 18, can exert a force on the glass tube 5. A suitable compressive force is applied to accommodate the fixing requirements of glass tubes 5 of different sizes. A compression plate 19, fixedly connected to the end of spring 18 away from glass tube 5, directly contacts the glass tube 5. The spring force of spring 18 applies compressive force to the glass tube 5, thereby fixing it in place. The design of the compression plate 19 allows for a certain degree of fit to the shape of the glass tube 5, improving the stability of the fixation. A drawer 3 is slidably connected inside the base 1. The drawer 3 can be used to store small tools or testing supplies, facilitating the classification, storage, and management of these items, further improving the convenience of the testing work.

[0026] Reference Figure 1 - Figure 3 A threaded rod 7 is fixedly connected to the upper surface of the support plate 8. A horizontal plate 9 is slidably connected to the outer wall of the threaded rod 7. A nut 10 is threadedly connected to the outer wall of the threaded rod 7. By tightening the nut 10, the horizontal plate 9 can be installed on the upper end of the threaded rod 7, thereby keeping the fuel injector 13 on the same plane. A threaded sleeve 16 is fixedly connected to the lower surface of the horizontal plate 9. The threaded sleeve 16 adjusts the clamping force of the elastic plate 15 on the fuel injector 13 by varying the depth of its interior. An elastic plate 15 is fixedly connected to the lower surface of the threaded sleeve 16. A compression sleeve 12 is threadedly connected to the outer wall of the threaded sleeve 16. The inner wall of the compression sleeve 12 is slidably connected to the outer wall of the elastic plate 15. The fuel injector 13 is slidably connected to the inner wall of the elastic plate 15. A threaded rod 17 is fixedly connected to the end of the fuel injector 13 near the horizontal plate 9. The outer wall of the threaded rod 17 is threadedly connected to the inner wall of the threaded sleeve 16. The end of the fuel injector 13 away from the horizontal plate 9 is positioned above the glass tube 5.

[0027] Specifically, the threaded rod one 7 is to provide a moving track and positioning reference for the horizontal plate 9. Through the threaded rod one 7, the horizontal plate 9 can slide up and down along the axial direction. The non-threaded area below the threaded rod one 7 is set to be larger in diameter to limit the movement of the horizontal plate 9. The horizontal plate 9 slidingly connected to the outer wall of the threaded rod one 7 serves as an important connection and adjustment platform. The installation of the horizontal plate 9 will extrude the oil nozzle 13 to keep the oil nozzle 13 at the same level. The nut 10 threadedly connected to the outer wall of the threaded rod one 7. The operator rotates the nut 10 to move the nut 10 on the threaded rod one 7 by using the transmission principle of threads, thereby extruding the horizontal plate 9 to keep the oil nozzle 13 at the same level. The threaded sleeve 16 fixedly connected to the lower surface of the horizontal plate 9 is used to connect the elastic plate 15 to enable the elastic plate 15 to be stably installed below the horizontal plate 9. On the other hand, the threaded sleeve 16 provides a threaded connection structure for the threaded rod two 17 to realize the stable connection between the oil nozzle 13 and the horizontal plate 9. At the same time, the threaded sleeve 16 is threadedly connected with the extrusion sleeve 12, which can indirectly adjust the clamping force of the elastic plate 15 on the oil nozzle 13 when adjusting the position of the extrusion sleeve 12. The elastic plate 15 fixedly connected to the lower surface of the threaded sleeve 16 uses its elastic properties to clamp the oil nozzle 13. During the installation of the oil nozzle 13, the elastic plate 15 can deform to a certain extent according to the shape of the oil nozzle 13 to tightly fit the outer wall of the oil nozzle 13, providing stable support to prevent the oil nozzle 13 from shifting or falling due to excessive force, thereby enhancing the fixing effect of the oil nozzle 13. The extrusion sleeve 12 threadedly connected to the outer wall of the threaded sleeve 16 can adjust its position on the threaded sleeve 16 by rotating the extrusion sleeve 12. When the extrusion sleeve 12 moves downward, it will extrude the elastic plate 15 to further tighten the elastic plate 15, thereby increasing the clamping force on the oil nozzle 13.Conversely, when the extrusion sleeve 12 moves upward, the clamping force of the elastic plate 15 will decrease, in this way, the fixing force of the oil nozzle 13 can be flexibly adjusted according to the actual situation of the oil nozzle 13, and the stability of the oil nozzle 13 during detection is ensured. The inner wall of the extrusion sleeve 12 is slidably connected to the outer wall of the elastic plate 15, which not only ensures that the extrusion sleeve 12 can smoothly move on the outer wall of the elastic plate 15 to adjust the clamping force of the elastic plate 15, but also improves the stability and accuracy of the adjustment process. The oil nozzle 13 is slidably connected to the inner wall of the elastic plate 15, so that the oil nozzle 13 can maintain a stable working position under the clamping of the elastic plate 15. The elastic clamping of the elastic plate 15 not only adapts to oil nozzles 13 of different shapes, but also effectively buffers the impact force generated by fuel injection when the oil nozzle 13 is working, preventing the oil nozzle 13 from shaking or falling off. The threaded rod two 17 fixedly connected to one end of the oil nozzle 13 close to the horizontal plate 9 is threadedly connected to the inner wall of the threaded sleeve 16, which realizes the detachable fixing between the oil nozzle 13 and the horizontal plate 9. The oil nozzle 13 is arranged above the glass tube 5 away from one end of the horizontal plate 9. Such a layout can make the fuel sprayed by the oil nozzle 13 accurately fall into the glass tube 5, which is convenient for observing and detecting the performance indicators such as fuel injection effect and flow.

[0028] Working principle: first, the glass tube is placed on the cleaner, the spring 18 inside the sliding plate 22 will push the extrusion plate 19 to apply extrusion force to the glass tube 5, because the spring 18 has elasticity, the extrusion plate 19 can be self-adaptive adjustment according to the shape and size of the glass tube 5, tightly fit the outer wall of the glass tube, realize the stable fixation of different size glass tube, when need to replace different outer diameter or length of glass tube, the sliding plate 22 can slide in the base 1 along a certain direction, the sliding plate 22 drives the connecting plate 11 to move through the connecting block 23, the slider 14 on the connecting plate 11 slides on the slide rail 4, ensure the smoothness and stability of movement, at the same time, the limiting ring 25 slides on the guide rod 20, the spring 26 provides reset elastic force, the limiting block 24 limits the sliding range of the limiting ring 25, can fix the moving position of the sliding plate 23, prevent rebound, when installing the oil nozzle 13, the threaded rod 17 is screwed into the inner wall of the threaded sleeve 16, realize the preliminary connection of the oil nozzle 13 and the horizontal plate 9, the elastic plate 15 will be deformed according to the shape of the oil nozzle 13, tightly fit the outer wall of the oil nozzle, provide certain support and fixation, by rotating the extrusion sleeve 12, the position of the extrusion sleeve 12 on the threaded sleeve 16 can be adjusted, when the extrusion sleeve 12 moves downward, the elastic plate 15 is extruded, so that it is further tightened, the clamping force on the oil nozzle 13 is increased; when it moves upward, the clamping force is reduced, so that the fixing force of the oil nozzle 13 can be flexibly adjusted to ensure its stability during detection, in addition, by rotating the nut 10, the horizontal plate 9 can slide up and down on the threaded rod 7 by using the threaded transmission principle, and then the height of the oil nozzle 13 is adjusted to make it accurately match the glass tube 5, so that the fuel sprayed by the oil nozzle 13 can accurately fall into the glass tube 5, after the fixation and position adjustment of the glass tube and the oil nozzle are completed, the oil nozzle is started to detect, the fuel sprayed by the oil nozzle 13 falls into the glass tube 5 below, the operator can observe the spraying effect, flow and other conditions of the fuel in the glass tube 5 to evaluate the performance index of the oil nozzle, the storage bin 2 can store cleaning liquid and other liquids required for cleaning and detection, and can be used to clean the oil nozzle or related parts before and after detection; the drawer 3 is used to store small tools or detection supplies, which can be taken at any time during operation.
