In the process of realizing the utility model, The inventor found that at least the following problems have not been solved in the prior art: although the handle assembly with adjustable length is provided to facilitate use and scraping; when the light is insufficient, scraping can be performed with auxiliary lighting by the lighting assembly; a magnifying glass is used to observe the sampling site for convenient scraping; the blade can be buffered when scraping to avoid scratching the skin and causing cross infection, and at the same time, it is easy to replace the blade and clean and disinfect the blade, but during use, the traditional skin sampling device cannot conveniently collect the skin scraped by the scraper, and the skin sample needs to be manually removed from the scraper. Moreover, after the sample is scraped, since the scraper is a plane, the sample is easy to fall from the surface of the scraper. For this reason, a new technical solution needs to be designed to solve the problem. Utility Model Content

[0022] Example 1: A skin sampling device, see Figures 1 to 3, including a device shell 1, and also including: a connecting block 2, fixed on one side of the device shell 1; a sampling mechanism, opened on one side of the connecting block 2, the sampling mechanism including a square hole 201, the square hole 201 is opened on one side of the connecting block 2, an arc block 202 is integrally formed on one side of the square hole 201, a sampling plate 203 passes through the inside of the square hole 201, an arc trough 204 is opened on one side of the sampling plate 203, the arc block 202 is engaged at the rear end of the arc trough 204, and the rear end of the sampling plate 203 extends into the device shell 1; a skin scraper 205 is arranged at the bottom of one side of the sampling plate 203, because the skin scraper 205 is arranged on the surface of the sampling plate 203, the device shell 1 can be held by hand, and the connecting block 2 can be pressed with fingers to move the sampling plate 203 and the skin scraper 205 to scrape and sample the skin surface of the patient, When scraping and sampling, the scraped skin sample will enter the arc trough 204, so that the skin sample will be collected. When the skin sample needs to be removed, the connecting block 2 can be directly pushed backward, thereby driving the sampling plate and the scraper to move backward, so that the arc trough 204 moves through the arc block 202, and the arc block 202 will push the skin sample in the arc trough 204, so that the arc block 202 will directly push the skin sample in the arc trough 204 out, and the skin sample can be directly pushed into the collection mechanism, eliminating the need for manual removal of the skin sample, and solving the problem of traditional skin sampling devices. The skin scraped by the scraper cannot be conveniently collected, and the skin sample needs to be manually removed from the scraper. Moreover, after the sample is scraped, since the scraper is a plane, the sample is easy to fall off the surface of the scraper.

[0023] For details, see Figure 2 A sliding hole 206 is provided on one side of the device shell 1, and a moving block 207 is attached to one side of the sliding hole 206. A moving strip 208 is fixed on one side of the moving block 207. The end of the moving strip 208 away from the moving block 207 passes through the sliding hole 206 and extends into the device shell 1. During the movement of the connecting block 2, the moving strip 208 will be driven to move. The moving strip 208 will drive the sampling plate 203 and the skin scraper 205 to move, thereby driving the sampling plate 203 and the skin scraper 205 to be stored and placed and moved out for scraping. At the same time, the moving strip 208 will also drive the slider 210 to move in the sliding groove 209 when moving, thereby limiting the moving strip 208 and the connecting block 2.

[0024] For further information, see Figure 2The sampling plate 203 is attached to one end of the movable strip 208 located in the device shell 1, and a first thread groove 3 is opened at the rear end of the sampling plate 203. The first thread groove 3 is threadedly connected with a first fixing bolt 301. The end of the first fixing bolt 301 away from the first thread groove 3 passes through the movable strip 208. Not only can the first fixing bolt 301 be threadedly connected to the first thread groove 3 on the surface of the sampling plate 203, but the sampling plate 203 can be conveniently disassembled and assembled by rotating the first fixing bolt 301. In addition, a second fixing bolt 303 is threadedly connected to the second thread groove 302 on the surface of the skin scraper 205. By rotating the second fixing bolt 303, the skin scraper 205 can be conveniently disassembled, assembled and replaced.

[0025] It is worth noting that see Figure 2 A slider 210 is fixed to one side of the movable strip 208 , and the slider 210 is slidably connected to a slide groove 209 opened on one side of the inner side of the device housing 1 .

[0026] It is worth noting that see Figure 3 A circular groove 304 is provided at the bottom of one side of the sampling plate 203, a second thread groove 302 is provided on one side of the skin scraper 205, a second fixing bolt 303 is threadedly connected to the inner part of the second thread groove 302, and one end of the second fixing bolt 303 away from the second thread groove 302 passes through the sampling plate 203 and extends into the circular groove 304.

[0027] It is worth mentioning that see Figure 1 A mounting hole 101 is installed on the top of the device housing 1 , and a cover plate 102 is installed inside the mounting hole 101 .

[0028] When using a skin sampling device, since a skin scraper 205 is provided on the surface of the sampling plate 203, the device housing 1 can be held by hand, and the connecting block 2 is pressed with fingers to move the sampling plate 203 and the skin scraper 205 to scrape and sample the patient's skin surface. When scraping and sampling, the scraped skin sample will enter the arc-shaped material groove 204, so that the skin sample is collected. When the skin sample needs to be removed, the connecting block 2 can be directly pushed backward, thereby driving the sampling plate and the scraper to move backward, so that the arc-shaped material groove 204 moves through the arc block 202, and the arc block 202 will push the skin sample in the arc-shaped material groove 204, so that the arc block 202 directly pushes out the skin sample in the arc-shaped material groove 204, and can directly push the skin sample into the collection mechanism, eliminating the need for manual removal of the skin sample. During the movement of the connecting block 2, the moving strip 208 will be driven to move, and the moving strip 208 will drive the sampling plate 203 and the skin scraper 205 to move, thereby driving the sampling plate 203 and the skin scraper 205 to be stored, placed and moved out for scraping. At the same time, the moving strip 208 will also drive the slider 210 to move in the slide groove 209 when moving, thereby limiting the moving strip 208 and the connecting block 2. Not only can the first fixing bolt 301 be threadedly connected to the first thread groove 3 on the surface of the sampling plate 203, and the first fixing bolt 301 can be rotated to conveniently disassemble and assemble the sampling plate 203, but also, the second fixing bolt 303 is threadedly connected to the second thread groove 302 on the surface of the skin scraper 205, and the skin scraper 205 can be conveniently disassembled, assembled and replaced by rotating the second fixing bolt 303.
