DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4The utility model provides a technical solution: a plasmid extraction kit, comprising a box body 1, a fixing block 2, a box cover 3, a lifting plate 4, a limiting block 5, a worm 6, a worm wheel 7, a limiting plate 8, a first rubber pad 9, a reagent bottle 10, a first built-in box 11, a second built-in box 12, a first connecting plate 13, a second connecting plate 14, a third connecting plate 15, a fourth connecting plate 16, a magnetic frame 17, a test tube rack 18, a second rubber pad 19 and a centrifugal test tube 20. When the plasmid extraction kit is used, Figure 1 , Figure 2 and Figure 4 First, the plasmid extraction kit can be carried to the position to be used through the lifting plate 4 rotatably connected to the box cover 3, and then the non-detachable worm 6 can be engaged in the limit block 5 fixedly connected to the rotating box cover 3, so that the worm 6 can rotate under the engagement limit of the limit block 5. Since the middle outer side of the limit block 5 is meshedly connected with a worm wheel 7 rotatably connected to the box cover 3, the middle outer side of the worm wheel 7 is fixedly connected with a limiting plate 8 with a "√"-shaped structure, and the limiting plate 8 is symmetrically arranged about the box cover 3, and the lower inner side of the limiting plate 8 is snap-fitted with a fixing block 2 fixedly connected to the box body 1. Therefore, through the rotation of the worm 6, it is easy to drive the worm wheel 7 to rotate in the opposite direction, so as to achieve the purpose of making the worm wheel 7 drive the limiting plate 8 outside it to rotate in the opposite direction, and disconnect the snap-fit ​​connection between the limiting plate 8 and the fixing block 2, thereby facilitating the disconnection of the snap-fit ​​fixation of the box cover 3 and the box body 1;

[0026] like Figure 1 , Figure 2 and Figure 3, and then the box cover 3 hingedly connected to the box body 1 can be rotated outward to disconnect the closed connection between the box cover 3 and the box body 1. Since the first built-in box 11 and the second built-in box 12 are arranged in parallel on the top of the box body 1, the first connecting plate 13, the second connecting plate 14 and the third connecting plate 15 are rotatably connected to the outer side of the upper left end, the outer side of the middle part of the upper end and the outer side of the upper right end of the first built-in box 11 respectively, the first connecting plate 13, the second connecting plate 14 and the third connecting plate 15 are arranged in parallel, and the lower ends of the first connecting plate 13 and the second connecting plate 14 are rotatably connected to the box body 1, the upper ends of the second connecting plate 14 and the third connecting plate 15 are rotatably connected to the second built-in box 12, and the lower end of the third connecting plate 15 is staggered and symmetrically provided with a fourth connecting plate 16 rotatable therewith, and the lower end of the fourth connecting plate 16 is rotatably connected to the box cover 3 Therefore, by rotating the box cover 3, it is convenient for the first built-in box 11 to slide toward the top outside the box body 1 under the driving of the fourth connecting plate 16 and the limiting of the first connecting plate 13 and the second connecting plate 14, and the second built-in box 12 to slide toward the top outside the box body 1 under the limiting driving of the second connecting plate 14 and the third connecting plate 15, so as to facilitate the purpose of quickly unfolding the plasmid extraction kit. Since the first rubber pad 9 with the inner side nested and fitted with the reagent bottle 10 is glued and fixed to the inner side of the lower end of the box body 1, the magnetic frame 17 and the test tube rack 18 are nested on the inner side of the first built-in box 11, and the second rubber pad 19 with the inner side snap-fitted and fitted with the centrifugal test tube 20 is glued and fixed on the inner side of the second built-in box 12, it is convenient to take and put the objects placed in the plasmid extraction kit for use;

[0027] like Figure 1 , Figure 2 and Figure 4 After the plasmid extraction is completed, the box cover 3 can be rotated to make the first built-in box 11 and the second built-in box 12 located on the inner side of the box body 1 and the box cover 3, so that the box cover 3 fits the upper surface of the box body 1, and then the worm 6 that is engaged and limited in the limit block 5 can be rotated to make the worm wheel 7 drive the limit plate 8 to rotate, so as to achieve the purpose of making the limit plate 8 fit and connect with the fixed block 2 by snapping, and the meshing and self-locking of the worm 6 and the worm wheel 7 facilitates the closure of the plasmid extraction kit to prevent the items therein from slipping off and falling off.
