In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
As shown in fig. 1 and 2, the flat plate bacterial colony collector of the present invention comprises a holding portion 10, a bacterial colony scraping portion 20 and an elastic supporting portion 30.
Specifically, the holding part 10 has a holding rod 101 and a flexible holding sleeve sleeved at one end of the holding rod 101, the holding rod 101 is a rigid straight rod, and the flexible holding sleeve is a rubber anti-slip sleeve 102 sleeved at the lower end of the holding rod 101; in addition, in order to further increase the friction force when the rubber anti-slip sleeve 102 is gripped and to facilitate gripping and stabilizing the gripping rod 101, the outer surface of the rubber anti-slip sleeve 102 can be designed to be an anti-slip rough surface with uniformly distributed convex points or inclined stripes.
The bacterial colony scraping part 20 is an arc-shaped scraping plate 201, a cutting edge 202 for scraping bacterial colonies on an agar plate is arranged on a straight edge on one side of the arc-shaped scraping plate 201, the arc-shaped scraping plate 201 adopts an arc-shaped structure, so that the bacterial colonies can be easily scraped, and an arc-shaped cavity is formed in the inner arc surface of the arc-shaped scraping plate 201, so that more bacterial colonies can be borne; in addition, as shown in fig. 3, the inner side of the cutting edge 202 is an arc structure connected with the inner arc surface of the arc scraper 201, and the outer side thereof is a plane structure capable of being attached to an agar plate, so that the bacterial colony can be scraped cleanly without waste, and the agar can be prevented from being scraped.
The elastic supporting portion 30 is a spiral supporting spring 301 which is consistent with the axis of the holding rod 101 (the bending degree of the spiral supporting spring 301 is less than 30 degrees, which can ensure that agar is not scraped), the spiral supporting spring 301 has a first connecting end 302 and a second connecting end 303, specifically, the upper end of the spiral supporting spring 301 extends upwards to form the first connecting end 302, the lower end of the spiral supporting spring 301 extends downwards to form the second connecting end 303, the axes of the first connecting end 302 and the second connecting end 303 should be consistent with the axis of the spiral supporting spring 301, and the spiral supporting spring 301 should be vertically fixedly connected to the center of the straight edge at the other side of the arc-shaped scraping plate 201 opposite to the cutting edge 202 through the first connecting end 302, the spiral supporting spring 301 should be fixedly connected to the end (i.e. the upper end of the holding rod 101) of the holding rod 101, which is far away from the rubber anti-slip sleeve 102 through the second connecting end 303, thereby forming a colony collector of an integrated structure.
