The scraper 4 is fixedly connected to the bottom end of the shaft rod 35. The scraper 4 includes a turntable 41, a scraper 42, an injection port 43, a scraping groove 44 and a funnel 45. The bottom end of the scraper 4 is fixedly connected to the sample storage bottle 5 through a thread. A scraping groove 44 is opened in the turntable 41, and an injection port 43 is arranged on the outside of the scraping groove 44. A scraper 42 is inserted on the outside of the turntable 41. The scraper 42 is located on the side of the injection port 43, and the extension line of the center line of the inner side of the scraper 42 does not pass through the center line of the turntable 41. The rotating disk 41 is arranged in a circular shape with the rotating disk 41 as the center. A funnel 45 is fixedly connected to the bottom of the rotating disk 41. The top of the funnel 45 is connected to the scraping groove 44. The top surface of the rotating disk 41 is fixedly connected to the bottom end of the shaft rod 35. The bottom end of the funnel 45 is fixedly connected to the mouth of the sample storage bottle 5 through a thread. The rotating disk 41 is driven to rotate by the scraper 4, and the rotating disk 41 drives the scraper 42 to rotate. After the scraper 42 scrapes the coating sample, the coating sample enters the scraping groove 44 under the rotation obstruction of the scraper 42. The coating sample in the scraping groove 44 leaks into the sample storage bottle 5 through the funnel 45 under the action of gravity. A fixing rod 21 is fixedly connected to the inner surface of the rear side wall of the frame 1. The front end of the fixing rod 21 is fixedly connected to the placement plate 2.
