[0028] In the application, after the bias column bevel end 218 or the sword bevel end 219 moves to the outside of the fixed cylinder 112, the first blocking block 113 or the second blocking block 114 is extruded out of the inside of the fixed cylinder 112, after the sliding block 216 starts to extrude the liquid storage tank 312, the second spring 314 in the inside of the liquid storage tank 312 starts to compress, so as to drive the whole liquid storage tank 312 to compress, at this time, the rust-proof oil in the inside of the liquid storage layer 313 is extruded, enters the inside of the smearing block 317 through the liquid outlet pipe 315, after the sliding block 216 is not under stress, the bias column bevel end 218 and the sword bevel end 219 start to reset, the side wall thereof rubs against the side wall of the smearing block 317, so as to smear the rust-proof oil on the side wall thereof, so as to play a rust-proof role, prevent the end head from being seriously rusted and being unable to be used subsequently.

[0029] The oblique end 218 and the sword end 219 of the bias column are slidingly connected inside the fixed cylinder 112. When the slider 216 is not under stress, the oblique end 218 and the sword end 219 of the bias column will start to reset, and the side wall will start to rub with the bottom side wall of the fixed cylinder 112. A group of sponge rings 115 are fixedly installed on the inner wall of the bottom of the fixed cylinder 112, which can scrape off the contaminants on the oblique end 218 and the sword end 219 of the bias column on the outer wall of the bottom of the fixed cylinder 112, thereby playing a cleaning role.

[0030] As shown in Figure 1 , 2 , 5 and Figure 6 , a group of lifting assemblies 2 are installed on the side wall of the extractor body 1. The inside of the lifting assembly 2 includes a fixed disc 210, a plurality of layered sleeve rods 211, a limiting box 212, a limiting block 213, a connecting disc 214, a first spring 215, a slider 216, a sliding groove 217, an oblique end 218 of a bias column, and a sword end 219. The fixed disc 210 is fixedly installed in the lower middle position of the outer wall of the extractor body 1. A plurality of limiting boxes 212 are fixedly installed on the fixed disc 210. A limiting groove is formed in the upper end of the limiting box 212. A group of limiting blocks 213 are slidingly connected to the upper side wall of the limiting box 212. A plurality of limiting boxes 212 are symmetrically arranged. The slider 216 is slidingly installed in the sliding rail formed on the outer wall of the extractor body 1. A group of sliding grooves 217 are formed on both sides of the slider 216. The size of the sliding groove 217 is consistent with the length, width and height of the limiting block 213. A group of connecting discs 214 are fixedly connected to the lower end of the slider 216. One end of the first spring 215 is fixedly connected to the lower end of the connecting disc 214. The other end of the first spring 215 is fixedly connected to the other connecting disc 214. The other connecting disc 214 is fixedly installed on the fixed disc 210. The output ends of two groups of layered sleeve rods 211 are fixedly connected to the lower end of the slider 216. The lower end of the layered sleeve rod 211 is fixedly connected to the fixed disc 210. Two groups of fixed discs 210 are located on both sides of the first spring 215. The first spring 215 is located between the two groups of limiting boxes 212. The oblique end 218 of the bias column is slidingly connected inside the fixed cylinder 112. A group of sword ends 219 are also slidingly connected inside the fixed cylinder 112. A group of insulating sleeves 110 are fixedly installed on the outer wall of the extractor body 1. A group of oblique ends 111 of cylinders are fixedly installed at the lower end of the extractor body 1. A group of fixed cylinders 112 are fixedly installed inside the oblique end 111 of the cylinder. A group of first blocking blocks 113 are slidingly connected inside the fixed cylinder 112. A group of second blocking blocks 114 are slidingly connected inside the fixed cylinder 112. The first blocking block 113 is located below the oblique end 218 of the bias column. The second blocking block 114 is located below the sword end 219.

[0031] In this invention, two sets of sliders 216 are slidably connected to both sides of the extractor body 1. One end of one set of sliders 216 is fixedly connected to the oblique cylindrical end 218, and the other set is fixedly connected to the sword-shaped end 219. If the cylindrical oblique end 111 type is required, it can be used directly. If the oblique cylindrical end 218 or sword-shaped end 219 type is required, the corresponding slider 216 is pressed and moved downwards. When the slider 216 is pressed, it will slide inside the slide rail opened on the side wall of the extractor body 1. The first spring 215... As compression begins, the multi-layer sleeve rod 211 will also begin to retract, and the corresponding oblique end 218 and sword end 219 will slide inside the fixed cylinder 112. When the side wall of the slider 216 enters the limiting groove opened on the limiting box 212, the limiting block 213 will slide. At this time, the limiting block 213 will enter the sliding groove 217, which will limit the slider 216 and prevent the slider 216 from resetting under the action of the first spring 215. This allows for quick changes in the port type, making it convenient for workers and improving work efficiency.

[0032] Working principle: Two sets of sliders 216 are slidably connected to both sides of the extractor body 1. One end of one set of sliders 216 is fixedly connected to the oblique cylindrical end 218, and the other set is fixedly connected to the sword-shaped end 219. If the cylindrical oblique end 111 type is required, it can be used directly. If the oblique cylindrical end 218 or sword-shaped end 219 type is required, the corresponding slider 216 is pressed and moved downwards. When the slider 216 is pressed, it will slide inside the slide rail opened on the side wall of the extractor body 1, and the first spring 215 will start to activate. As the compression occurs, the multi-layer sleeve 211 will also begin to retract, and the corresponding oblique end 218 and sword end 219 will slide inside the fixed cylinder 112. When the side wall of the slider 216 enters the limiting groove opened on the limiting box 212, and then the limiting block 213 slides, the limiting block 213 will enter the sliding groove 217, thus limiting the slider 216 and preventing it from resetting under the action of the first spring 215. After the oblique end 218 or sword end 219 moves to the outside of the fixed cylinder 112, the first blocking block... 113 or the second barrier block 114 will be squeezed out of the fixed cylinder 112. After the slider 216 starts to squeeze the liquid storage tank 312, the second spring 314 inside the liquid storage tank 312 starts to compress, thereby driving the entire liquid storage tank 312 to compress. At this time, the anti-rust oil inside the liquid storage layer 313 will be squeezed out and enter the interior of the coating block 317 through the liquid outlet pipe 315. After the slider 216 is no longer under force, the oblique end 218 and the sword end 219 of the eccentric column will start to reset, and their sidewalls will rub against the sidewalls of the coating block 317, thereby removing the anti-rust oil. Rust-preventing oil is applied to its sidewalls. The oblique end 218 and the sword end 219 are slidably connected inside the fixed cylinder 112. When the slider 216 is no longer under force, the oblique end 218 and the sword end 219 will begin to reset, and their sidewalls will begin to rub against the bottom sidewall of the fixed cylinder 112. A set of sponge rings 115 are fixedly installed on the bottom inner wall of the fixed cylinder 112, which will scrape the contaminants on the oblique end 218 and the sword end 219 onto the bottom outer wall of the fixed cylinder 112, thereby achieving a cleaning effect.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
