The two fixing columns are respectively movably connected to two sleeve columns. The upper ends of the two sleeve columns are respectively fixedly connected to the lower surfaces of two pressing blocks. Connecting rods are movably connected to the front and rear sides of the two pressing blocks.

[0004] The above device can drive two clamping blocks to move away from each other, so that they no longer clamp the reagent tubes placed inside the kit, and it is convenient to take out the reagent tubes from the inside of the kit. However, the structure of the above device is complex and occupies a large amount of space inside the kit. Although it is convenient for users to take out the reagent tubes from the inside of the kit, only a small number of reagent tubes can be stored inside the kit. For this reason, a fluorescence antigen detection kit is proposed. Summary of the Utility Model

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 and Figure 2 , a fluorescent antigen detection reagent kit, including a reagent kit body 1, on which a sealing box cover 4 is movably installed, an upper positioning plate 2 is fixedly installed at the upper end of the reagent kit body 1, a lower positioning plate 5 is fixedly installed at the bottom of the reagent kit body 1, positioning card slots 3 are opened on both the upper positioning plate 2 and the lower positioning plate 5, a limiting mechanism 6 is connected in the positioning card slot 3 on the upper positioning plate 2, the limiting mechanism 6 includes an annular inflatable airbag 601 fixed in the upper positioning plate 2, a connecting pipeline 602 is arranged between the annular inflatable airbags 601, a pressing mechanism 7 is connected to the driving pressure rod 607, after the sealing box cover 4 is covered, the piston 606 will move downward, thereby squeezing the gas into the annular inflatable airbag 601, making the annular inflatable airbag 601 expand, restricting the reagent tube in the positioning card slot 3, and after the sealing box cover 4 is opened, the gas in the annular inflatable airbag 601 can be inhaled into the inflating cylinder body 604, making the annular inflatable airbag 601 contract, and loosening the reagent tube in the positioning card slot 3.

[0023] Please refer to again Figure 2 and Figure 3, the limiting mechanism 6 includes an annular air bag 601 fixed inside the upper positioning plate 2. A connecting pipe 602 is provided between the annular air bags 601. A charging cylinder body 604 is fixedly installed inside the reagent kit body 1. A return spring 605 is arranged inside the charging cylinder body 604. A piston 606 is movably installed inside the charging cylinder body 604. A driving pressure rod 607 is fixedly installed at the upper end of the piston 606. The limiting mechanism 6 further includes a gas pipe 603 arranged at the bottom of the charging cylinder body 604.

[0024] Specifically, after the pressing base 701 rotates downward, the movable ball 705 will roll along the movable chute 702 and move downward. After the movable ball 705 moves downward, it will drive the ball seat 706 to move downward, thereby pressing the driving pressure rod 607 downward. The downwardly pressed driving pressure rod 607 will drive the piston 606 to move downward, thereby squeezing the gas in the charging cylinder body 604 into the annular air bag 601, causing the annular air bag 601 to expand and restricting the reagent tube in the positioning slot 3, facilitating the fixation of the reagent tube.

[0025] Please refer to again Figure 2 and Figure 4 , the pressing mechanism 7 includes a ball seat 706 fixed to the upper end of the driving pressure rod 607 and a pressing base 701 fixed to the inner wall of the sealing cover 4. An movable chute 702 is provided on the pressing base 701. A movable ball 705 is movably installed at the upper end of the ball seat 706. A docking screw hole 707 is provided at the bottom of the ball seat 706. Positioning support feet 703 are fixedly installed at both ends of the pressing base 701. Positioning through holes 704 are provided on the positioning support feet 703.

[0026] Specifically, after the sealing cover 4 is opened, the upper end of the driving pressure rod 607 will lose the block. At this time, the return spring 605 will reset. When the return spring 605 resets, it will drive the piston 606 to move upward, sucking the gas in the annular air bag 601 into the charging cylinder body 604, causing the annular air bag 601 to contract and loosening the reagent tube in the positioning slot 3, facilitating the user to take out the reagent tube from the inside of the reagent kit.

[0027] Working principle: When in use, the reagent tube can be placed into the positioning card slot 3. After the reagent tube is placed into the positioning card slot 3, the sealing box cover 4 can be covered. After covering the sealing box cover 4, when the base 701 is pressed down, it will rotate downward. After the base 701 rotates downward, the movable ball 705 will roll along the movable chute 702 and move downward. After the movable ball 705 moves downward, it will drive the ball seat 706 to move downward. After the ball seat 706 moves downward, it will press down the driving pressure rod 607. The pressed-down driving pressure rod 607 will drive the piston 606 to move downward. When the piston 606 moves downward, it will squeeze the gas in the charging cylinder body 604 into the annular charging airbag 601, causing the annular charging airbag 601 to expand and restricting the reagent tube in the positioning card slot 3. At the same time, the user can open the sealing box cover 4. After opening the sealing box cover 4, the upper end of the driving pressure rod 607 will lose the block. Since one end of the return spring 605 is connected to the bottom of the charging cylinder body 604 and the other end of the return spring 605 is connected to the piston 606, after the upper end of the driving pressure rod 607 loses the block, the return spring 605 will reset. When the return spring 605 resets, it will drive the piston 606 to move upward, thereby sucking the gas in the annular charging airbag 601 into the charging cylinder body 604, causing the annular charging airbag 601 to contract. After the annular charging airbag 601 contracts, the reagent tube in the positioning card slot 3 will become loose, facilitating the user to take out the reagent tube from the inside of the reagent kit.
