[0002] Smear is a method of detecting pathogens in blood or tissues, including gonococci, cryptococcus neoformans, syphilis spirochetes, diphtheriae and other pathogens. In order to facilitate the preparation of smears, a smear maker is usually used. The smear maker is a medical device used to make various cytological smears, that is, to spread cell samples on a slide for microscopic examination and diagnosis. However, the current smear maker still has the following shortcomings:

[0003] For example, the patent document with application number 202122717871.3 discloses a medical test smear maker. The smear maker is provided with folding rods on both sides of the placement plate, and the push-pull assembly slides on the folding rods through the sliding ring, and then the push-pull assembly is pressed downward, and the double-concave push piece clamped by the elastic clamp can contact the slide, so that the blood is evenly smeared on the slide. However, during the production, the slide is not firmly limited, and the cover glass is not stable enough when covered, which is easy to be misplaced.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a smear maker is proposed. Utility Model Content
