[0020] As a further improvement, a spring 14 is installed between the sleeve 11 and the core tube 13 and below the adjusting tube 10. The upper end of the spring 14 is connected to the adjusting tube 10. The lower end of the inner wall of the adjusting tube 10 is a trumpet-shaped structure. The spring 14 gives the adjusting tube 10 a certain support and rebound performance.

[0021] As a further improvement, the interior of the barrel body 1 is rotatably connected to a fixing frame 20, an axle rod 22 is installed on the inner bottom of the barrel body 1 and the upper end of the axle rod 22 is rotatably connected to the fixing frame 20, an adjusting rod 16 is installed on the upper end of the fixing frame 20, the upper end of the adjusting rod 16 passes through the barrel body 1 and is threadedly connected to an adjusting disk 5, and rotating the adjusting disk 5 can drive the fixing frame 20 to rotate, and after the fixing frame 20 rotates, the liquid storage cylinders 19 at different positions are rotated to the liquid inlet 18.

[0022] As a further improvement, a plurality of mounting grooves 21 are provided at the upper end of the fixing frame 20, and a liquid storage cylinder 19 is embedded and connected in the mounting groove 21. The plurality of liquid storage cylinders 19 can classify oils in different states. An oil guide hole is provided on the side wall of the liquid storage cylinder 19, and a pull ring 15 is installed at the upper end of the liquid storage cylinder 19 to facilitate the replacement of the liquid storage cylinder 19.

[0023] As a further improvement, a rubber liquid guide plate 17 is provided on the inner wall of the barrel body 1 and below the liquid inlet 18, and the end of the rubber liquid guide plate 17 extends into the oil guide hole. During the process of inserting the fixing frame 20 into the barrel body 1, the rubber liquid guide plate 17 is squeezed and bent until the oil guide hole is located at the rubber liquid guide plate 17, and the rubber liquid guide plate 17 rebounds and the end extends into the oil guide hole.

[0024] As a further improvement, an observation window 2 is provided on the outer wall of the barrel body 1, through which the internal state of the barrel body 1 can be observed, and moving wheels are installed at the lower end of the barrel body 1, which can improve the convenience of the equipment and facilitate moving to the working position.

[0025] Working principle: move the barrel body 1 to the side of the car, pull out the guide tube 6 to place the oil guide mechanism under the car body, find the oil drain hole, open the anti-fouling cover 7 towards the oil drain hole, open the bolts at the oil drain hole, and turn on the negative pressure machine 4 at the same time. The waste oil falls directly into the anti-fouling cover 7 and enters the core tube 13 through the liquid inlet hole 12 under the influence of negative pressure. The threaded end of the core tube 13 is connected to the oil drain hole. As the core tube 13 is tightened, the car body presses down on the regulating tube 10, and the regulating tube 10 moves down and blocks the liquid inlet hole 12, so that normal extraction can be carried out. When it is necessary to switch to the next liquid storage cylinder 19, rotate the regulating disk 5 to drive the fixing frame 20. After the barrel cover 3 is removed, take out the barrel cover 3 together with the fixing frame 20, loosen the regulating disk 5 to remove the barrel cover 3, and the liquid storage cylinder 19 can be replaced.

[0026] The utility model comprises 1, barrel body; 2, observation window; 3, barrel cover; 4, negative pressure machine; 5, adjustment plate; 6, conduit; 7, anti-fouling cover; 8, anti-fouling joint; 9, threaded structure; 10, adjustment tube; 11, sleeve; 12, liquid inlet; 13, core tube; 14, spring; 15, pull ring; 16, adjustment rod; 17, rubber liquid guide plate; 18, liquid inlet; 19, liquid storage cylinder; 20, fixing frame; 21, mounting groove; 22, shaft rod, and all the components are universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. The utility model solves the problem that the existing oil extractor for dismantling scrap cars needs to open the bolts at the oil drain hole when in use, and the bolts at the oil drain hole need to be opened when the conduit 6 of the extractor is connected to the drain machine. The oil hole is threadedly connected. When the bolt at the oil drain hole is opened, the oil flows out due to the large pressure difference between the inside and the outside, and drips onto the ground or the operator, which easily affects the surrounding environment. The utility model combines the above-mentioned components. When in use, the opening of the anti-fouling cover 7 is upward and located below the oil drain hole. Then the bolt at the oil drain hole is removed, and the internal oil will fall into the anti-fouling cover 7. The oil in the anti-fouling cover 7 is affected by the negative pressure and enters the core tube 13 through the liquid inlet hole 12, and then is guided to the inside of the barrel body 1 by the conduit 6. The core tube 13 is threadedly connected to the oil drain hole. As the core tube 13 is tightened, the vehicle body presses down on the regulating tube 10, and the regulating tube 10 moves down and blocks the liquid inlet hole 12, so that the problem of waste oil spilling during the oil extraction process can be avoided.

[0027] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
