Slot 701, positioning card slots 101 are provided on the upper surfaces of both sides of the box body 1, a base 3 is provided at the bottom of the box body 1, a connecting groove 102 is provided on the lower surface of the front side of the box body 1, a shielding plate 4 is provided inside the connecting groove 102, a handle 201 is provided on the top of the top plate 2, an extension block 205 is provided at the bottom of the top plate 2, and storage grooves 203 are provided on the middle surfaces of both sides of the extension block 205, a positioning spring 204 is provided inside the storage groove 203, and a positioning card block 202 is provided at the outer end of the positioning spring 204.
[0024] The support frame 5 is fixedly contacted and connected with the upper inner wall of the box body 1, and the rubber bottom plate 6 is fixedly contacted and connected with the inner side of the support frame 5. The support frame 5 and the rubber bottom plate 6 are provided to provide a stable placement space for the placement plate 9 placed above, so as to avoid the placement plate 9 from tilting when placed inside the box body 1. A plurality of placement holes 11 and storage tubes 12 are provided, and the plurality of placement holes 11 are connected and connected with the surface of the placement plate 9 in an inlaid manner. The height of the plurality of storage tubes 12 is less than 50 mm, and the plurality of storage tubes 12 are connected and contacted with the inside of the placement hole 11. The height of the placement plate 9 is 50 mm, and the surface of the placement plate 9 is connected to the grid groove 10. The placement plate 9 is connected with the upper surface of the support frame 5 and the rubber bottom plate 6 by means of a recessed connection, and the two ends of one side of the pressing plate 7 are connected with the recessed connection of the groove 701. The bottom of the pressing plate 7 is fixedly connected with the grid bar 8. The pressing plate 7 is connected with the upper surface of the placement plate 9 by means of a positioning engagement connection between the grid bar 8 and the grid groove 10. The setting of the pressing plate 7, the grid bar 8 and the grid groove 10 can prevent different storage tubes 12 from storing different gel DNA reagents and causing mixing. The upper surfaces on both sides of the box body 1 are connected with the positioning card slots 101 by means of the positioning card slots 101. It can provide a locking space for the positioning card block 202 to avoid the active separation between the top plate 2 and the box body 1 during the process of pulling the handle 201, which will cause damage to the gel DNA reagent stored in the box body 1. The bottom of the box body 1 is fixedly contacted and connected with the base 3, and the connecting groove 102 is connected with the lower surface of the front side of the box body 1 in an inlaid manner.

The shielding plate 4 can reduce the degree of contamination inside the box body 1. The handle 201 is fixedly contacted and connected with the top of the top plate 2, and the extension block 205 is fixedly connected to the bottom of the top plate 2 The contact connection is connected to the suspended support on the upper inner side of the box body 1, and the middle surfaces of the two sides of the extension block 205 are recessed and connected with the storage slot 203. There are two positioning springs 204 and two positioning blocks 202. The inner ends of the two positioning springs 204 are fixedly contacted and connected with the inner surface of the storage slot 203. The two positioning blocks 202 are telescopically connected and positioned internally in the positioning slot 101 through the telescopic performance of the positioning springs 204. The positioning springs 204 are set to keep the positioning block 202 in an outwardly extended state at any time to prevent the positioning block 202 from detaching from the positioning slot 101.
[0025] Working principle: First, press the positioning blocks 202 on both sides of the outside of the box body 1, and then pull the handle 201 to drive the top plate 2 as a whole and the extension block 205 to separate from the top of the box body 1, and use the groove 701 to pull upwards to separate the pressure plate 7 from the top of the placement plate 9, so that the storage tube 12 for collecting gel DNA is directly exposed. Because the height of the storage tube 12 is not conducive to separation from the placement hole 11, the shielding plate 4 at the bottom of one side of the box body 1 can be pushed, and the hand enters the bottom of the placement plate 9 at the bottom of the inside of the box body 1 through the connecting groove 102, and applies an upward thrust to the rubber bottom plate 6 at the bottom of the storage tube 12 where the gel DNA is required to be stored, so that the height level of the storage tube 12 is higher than the placement hole 11, which is convenient for taking out the storage tube 12 for storing gel DNA.
