[0024] The working principle and use process of the present invention are as follows: First, when the medical staff needs to take samples, they inject the required preservation liquid into the sample transport bottle 219. The preservation liquid will isolate the air from the sampling rod inserted into the sample transport bottle 219 to prevent cross contamination of the new sampling rod. Then, a new disposable protective cover 205 is put on the outer position of the fixed cylinder 202. Then, the operator picks up the fixed cylinder 202 by the handle 227, and aligns one end of the conical groove 206 with the oral cavity of the person being collected. At this time, the disposable protective cover 205 will cover the outer periphery of the mouth of the person being collected. The gas generated by the breathing of the person being collected will blow toward the disposable protective cover 205. At this time, these gases will be blown back toward the person being collected, thereby reducing the gas containing pathogens blowing toward the medical staff, thereby initially protecting the medical staff. Then the medical staff starts the lifting mini motor 210 through the control button 228, and drives the active roller 209 to rotate through the lifting mini motor 210. When the active roller 209 rotates, it can push the sampling rod inside the fixed tube 207 through the squeezing of the driven roller 208. At this time, the sampling rod will move to the position of the conical groove 206 on the inner side of the fixed tube 207, and after the sampling rod is inserted into the posterior pharyngeal wall or bilateral tonsil position of the sampled person, the control button 228 is used again to control the driving mini motor 232 to start. At this time, the mini motor 232 can be driven to drive the rotating roller 230 to rotate at the middle position of the limiting plate 229 and the pressing plate 231. At this time, under the limitation of multiple rotating rollers 230, the rotating roller 230 can drive the sampling rod to rotate slowly, thereby driving the sampling end of the sampling rod to scrape the position of the posterior pharyngeal wall of the sampled person to quickly perform sampling. Then, the lifting mini motor 210 is started again to drive the active roller 209 to rotate in the opposite direction. At this time, the sampling rod can be withdrawn to the inner side of the fixed cylinder 202. At this time, the end containing the collected material will stay on the inner side of the disposable protective cover 205. Then the operator moves the fixed cylinder 202 to the inner side of the shedding rod 313, and at the same time lifts the fixed cylinder 202 upward so that the disposable protective cover 205 can be removed from the outer side of the fixed cylinder 202 through the shedding rod 313, and at the same time, the disposable protective cover 205 will fall into the medical waste bin at the bottom. Subsequently, the servo motor 217 can be controlled to rotate through the internal controller, and the servo motor 217 can drive the rotating rod 214 inside the supporting plate 213 to rotate, and then the rotating column 215 can be driven to rotate through the rotating rod 214. At this time, the connecting rod 218 and the internal sample transport bottle 219 can be driven to rotate through the rotating column 215, and then the sample transport bottle 219 is rotated to the position of the placement slot 220. Then the medical staff inserts the fixed cylinder 202 into the inner position of the placement slot 220. At this time, the fixed cylinder 202 will be clamped on the top of the mounting shell 1 through the clamping ring 203, and then the sample transport bottle 219 at the bottom will be aligned with the fixed tube 207 at the top. Then the operator can control the lifting mini motor 210 to continue to rotate, so that the sampling rod can be pushed downward, and after the sampling rod is completely pushed out of the fixed tube 207, it will fall into the interior of the sample transport bottle 219; Then, the servo motor 217 is controlled to continue to rotate, so that the sample transport bottle 219 can be rotated to the bottom position of the sampling slot 226. At this time, the sealing cover of the sample transport bottle 219 can be inserted into the inner side of the rubber clamp 225. Then, the internal controller controls the electric telescopic rod 223 to extend downward, so that the locking tube 224, the rubber clamp 225 and the sealing cover can be extended downward. When the electric telescopic rod 223 is continuously extended downward, the sealing cover can be clamped at the outer position of the sample transport bottle 219. Then, the electric telescopic rod 223 is continuously controlled to retract, so that the sample transport bottle 219 is lifted up and moved to the outer position of the sampling slot 226. At this time, the operator can remove the sample transport bottle 219 from the bottom of the locking tube 224, and then place an empty sample transport bottle 219 to the inner side of the connecting rod 218. The sampling rod inside the fixed tube 207 can be pushed by squeezing the active roller 209 and the driven roller 208. After the sampling rod is inserted into the posterior pharyngeal wall or bilateral tonsil position of the sampled person, the mini motor 232 is started by controlling the control button 228. At this time, under the limit of multiple rotating rollers 230, the sampling rod can be driven to rotate slowly by the rotating rollers 230, thereby driving the sampling end of the sampling rod to scrape the posterior pharyngeal wall of the sampled person to quickly collect samples, without the operator manually operating the sampling rod to extend into the oral cavity of the sampled person, thereby reducing the contact between medical staff and the sampled person, preventing pathogens from spreading and infecting medical staff, and quickly completing the sampling. After sampling, the fixed cylinder 202 is inserted into the inner side of the placement slot 220, and then the sample transport bottle 219 is moved to the fixed The bottom of the fixed cylinder 202 can then be automatically inserted into the inner side of the sample transport bottle 219. This process automatically aligns the sampling stick with the sample transport bottle 219 and completes the placement without the medical staff having to manually insert the sampling stick, further reducing the medical staff's contact with the sampling stick containing pathogens and reducing the risk of infection. Finally, by rotating the sample transport bottle 219 to the bottom of the sampling slot 226, and then controlling the locking tube 224 to lock the sealing cover on the outer side of the sample transport bottle 219, the sample transport bottle 219 can be taken out. During the whole process, the medical staff will not touch the sampling stick at all, thereby quickly completing the throat swab sampling, further improving the protection level during the sampling process, ensuring the sampling efficiency, and improving the protection level of the medical staff from multiple conveniences, ensuring the operation safety of the medical staff and improving the collection safety. Finally, the medical staff controls the rotating column 215 to continue to rotate, so that the limit connecting rod 301 can be rotated to the bottom position of the placing funnel 310. At this time, the new sampling stick can be inserted into the inner position of the placing funnel 310, and then the sampling stick will fall to the inner position of the sliding cylinder 303 at the bottom through the through hole 311, and the rotating column 215 is continued to be controlled to rotate. At this time, the sliding cylinder 303 will rotate to the top position of the pad frame 308 and the pushing inclined plate 309. At this time, the pushing rod 306 will move toward the top along the pushing inclined plate 309, thereby pushing the sliding cylinder 303 to slide upward by pushing the inclined plate 309, and the limit sliding plate on the outside of the sliding cylinder 303 304 will slide on the inner side of the limiting slide groove 305 to prevent the sliding cylinder 303 from rotating during the rotation. At this time, the sampling rod inside the sliding cylinder 303 will move upward and be inserted into the inner side of the fixed tube 207 inside the conical groove 206, and the active roller 209 will be controlled to rotate so as to insert the sampling rod into the inner side of the fixed cylinder 202, thereby completing the addition of the sample, and after the push rod 306 passes through the pushing inclined plate 309, it will fall back to the initial position, and the medical staff can also observe the internal operating status of the installation shell 1 through the observation window 312, and can easily and quickly place the sampling rod to the inner side of the fixed cylinder 202, further improving work efficiency.
