[0030] like Figure 1 , 2 , 5 and Figure 6 As shown, a set of lifting components 2 are installed on the side wall of the extractor body 1, and the interior of the lifting component 2 includes a fixed plate 210, a multi-layer sleeve rod 211, a limit box 212, a limit block 213, a connecting plate 214, a first spring 215, a slider 216, a slide groove 217, a bias column oblique end 218 and a sword end 219. The fixed plate 210 is fixedly installed at the middle and lower position of the outer wall of the extractor body 1, and multiple sets of limit boxes 212 are fixedly installed on the fixed plate 210. The upper end of the limit box 212 is provided with a limit groove. A group of limit blocks 213 are slidably connected to the middle and upper positions of the side walls of the limit box 212. The multiple groups of limit boxes 212 are symmetrical to each other. The slider 216 is slidably installed in the slide rail provided on the outer wall of the extractor body 1. A group of slide grooves 217 are provided on both sides of the slider 216. The size of the slide grooves 217 is consistent with the length, width and height of the limit block 213. The lower end of the slider 216 is fixedly connected to a group of connecting plates 214. The lower end of the connecting plate 214 is fixedly connected to one end of the first spring 215. The other end of the first spring 215 is fixedly connected to Another set of connecting plates 214 is connected, and another set of connecting plates 214 is fixedly installed on the fixed plate 210. The lower end of the slider 216 is fixedly connected to the output ends of the two sets of multi-layer sleeve rods 211. The lower ends of the multi-layer sleeve rods 211 are fixedly connected to the fixed plate 210. The two sets of fixed plates 210 are located on both sides of the first spring 215. The first spring 215 is located between the two sets of limit boxes 212. The oblique end 218 of the offset column is slidably connected to the inside of the fixed cylinder 112. The inside of the fixed cylinder 112 is also slidably connected to a set of sword ends 21 9. A group of insulating sleeves 110 are fixedly installed on the outer wall of the extractor body 1, a group of cylindrical oblique ends 111 are fixedly installed on the lower end of the extractor body 1, a group of fixed cylinders 112 are fixedly installed inside the cylindrical oblique ends 111, a group of first blocking blocks 113 are slidably connected inside the fixed cylinders 112, a group of second blocking blocks 114 are slidably connected inside the fixed cylinders 112, the first blocking blocks 113 are located below the oblique end 218 of the side column, and the second blocking blocks 114 are located below the sword end 219.

[0031] In the present invention, two groups of sliders 216 are slidably connected on both sides of the extractor body 1, one end of one group of sliders 216 is fixedly connected to the eccentric column oblique end 218, and the other group is fixedly connected to the sword end 219. If the cylindrical oblique end 111 type is required, it can be used directly. If the eccentric column oblique end 218 or the sword end 219 type is required, the corresponding slider 216 can be pressed and moved downward. When the slider 216 is squeezed, the slider 216 will slide inside the slide rail opened on the side wall of the extractor body 1, and the first spring 215 When compression starts, the multi-layer sleeve rod 211 will also start to close, and the corresponding oblique end 218 and sword end 219 of the side column will slide inside the fixed tube 112. When the side wall of the slider 216 enters the limit groove opened on the limit box 212, the limit block 213 will slide. At this time, the limit block 213 will enter the inside of the slide groove 217 to limit the slider 216 and prevent the slider 216 from resetting under the drive of the first spring 215. The port type can be quickly changed, which is convenient for the staff to work and thus improves work efficiency.

[0032] Working principle: Two sets of sliders 216 are slidably connected on both sides of the extractor body 1, one end of one set of sliders 216 is fixedly connected to the eccentric column oblique end 218, and the other set is fixedly connected to the sword end 219. If the cylindrical oblique end 111 type is required, just use it directly. If the eccentric column oblique end 218 or the sword end 219 type is required, press and hold the corresponding slider 216 to move downward. When the slider 216 is squeezed, the slider 216 will slide inside the slide rail opened on the side wall of the extractor body 1, and the first spring 215 starts to move. When the multi-layer sleeve rod 211 is compressed, the multi-layer sleeve rod 211 will also begin to close, and the corresponding oblique end 218 of the eccentric column and the sword end 219 will slide inside the fixed cylinder 112. When the side wall of the slider 216 enters the limiting groove provided on the limiting box 212, the limiting block 213 will slide again. At this time, the limiting block 213 will enter the inside of the sliding groove 217 to limit the slider 216, preventing the slider 216 from resetting under the drive of the first spring 215. After the oblique end 218 or the sword end 219 of the eccentric column moves to the outside of the fixed cylinder 112, the first blocking block 113 or the second blocking block 114 will be squeezed out of the fixed cylinder 112. When the slider 216 starts to squeeze the liquid storage box 312, the second spring 314 inside the liquid storage box 312 starts to compress, thereby driving the entire liquid storage box 312 to compress. At this time, the anti-rust oil inside the liquid storage layer 313 will be squeezed and enter the inside of the smear 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 offset column will start to reset, and their side walls will rub against the side walls of the smear block 317, thereby Rust oil is applied on its side wall to prevent rust, and the oblique end 218 and the sword-shaped end 219 of the eccentric column are slidably connected to the inside of the fixed cylinder 112. When the slider 216 is no longer under force, the oblique end 218 and the sword-shaped end 219 of the eccentric column will begin to reset, and their side walls will begin to rub against the bottom side walls of the fixed cylinder 112. A group of sponge rings 115 are fixedly installed on the bottom inner wall of the fixed cylinder 112, which will scrape off the contaminants on the oblique end 218 and the sword-shaped end 219 of the eccentric column on the bottom outer wall of the fixed cylinder 112, thereby playing a cleaning role.
