[0024] like Figures 1 to 7 As shown, it includes a fixing frame 1, a storage frame 2 is slidably connected to the inner side of the top of the fixing frame 1, and a cover plate 3 is provided on one side of the top of the fixing frame 1. In order to facilitate the connection of the cover plate 3 with the fixing frame 1, a driving shaft 12 is fixed inside the cover plate 3 on the side close to the fixing frame 1, and the driving shaft 12 is rotatably connected to the fixing frame 1. In order to facilitate the opening of the cover plate 3, a handle 6 is fixed to the top of the cover plate 3 on the side away from the driving shaft 12. A lifting assembly is provided on the inner side of the lower end of the fixing frame 1 and at a position corresponding to the driving shaft 12. A plurality of positioning holes 4 are evenly opened on the top of the storage frame 2, a placement groove 5 is opened at the bottom of the inner side of the storage frame 2 and at a position corresponding to the positioning holes 4, and a clamping assembly is provided on the inner side of the storage frame 2 and at a position corresponding to the positioning holes 4;

[0025] The clamping assembly includes a driving plate 17, which is arranged on the inner side of the placement groove 5. The driving plate 17 is slidably connected to the placement groove 5. A plurality of telescopic springs 18 are evenly fixed to the lower end of the driving plate 17. The end of the telescopic spring 18 away from the driving plate 17 is fixedly connected to the storage rack 2. Connecting rods 19 are fixed on both sides of the driving plate 17. The connecting rods 19 are slidably connected to the storage rack 2. In order to be able to clamp the test tube or reagent bottle to the lower limit, the clamping plates 16 are slidably connected on both sides of the inner side of the positioning hole 4. A transmission assembly is provided on the end of the connecting rod 19 close to the clamping plate 16, and the clamping plate 16 is connected to the connecting rod 19 through the transmission assembly.

[0026] The lifting assembly includes a bidirectional screw 7, which is laterally arranged at the inner bottom position of the fixed frame 1. The bidirectional screw 7 is rotatably connected to the fixed frame 1, and the outer side of the bidirectional screw 7 is symmetrically threaded with a movable base 8. The movable base 8 is slidingly connected to the fixed frame 1. In order to facilitate the lifting and lowering of the storage rack 2 when the movable base 8 moves, the top of the movable base 8 is rotatably connected to an adjusting rod 9, and the end of the adjusting rod 9 away from the movable base 8 is rotatably connected to the storage rack 2.

[0027] A driving gear 13 is fixed to one end of the driving shaft 12, and a transmission rod 15 is rotatably connected to the inner side of the fixed frame 1 and close to the driving gear 13. In order to drive the transmission rod 15 to rotate when the driving gear 13 rotates, a driven gear 14 is fixed to one end of the transmission rod 15 close to the driving gear 13, and the driven gear 14 is meshed with the driving gear 13. In order to drive the bidirectional screw 7 to rotate simultaneously when the transmission rod 15 rotates, a transmission gear 10 is fixed to the other end of the transmission rod 15 and the end of the bidirectional screw 7, and the two transmission gears 10 are connected by a transmission chain 11.

[0028] The transmission assembly includes a drive frame 20, which is fixed to one end of the connecting rod 19 near the clamping plate 16. A transmission rack 24 is fixed to the inner side of the drive frame 20. In order to facilitate the movement of the clamping plate 16, a built-in threaded rod 21 is fixed to the side of the clamping plate 16 near the drive frame 20. The built-in threaded rod 21 is slidably connected to the storage rack 2. In order to drive the built-in threaded rod 21 to move, the inner side of the end of the built-in threaded rod 21 away from the clamping plate 16 is threadedly connected to a clamping screw 23. The clamping screw The rod 23 is rotatably connected to the storage rack 2. In order to facilitate the rotation of the clamping screw 23 when the driving rack 20 moves, a clamping gear 25 is fixed at the position corresponding to the clamping screw 23 and the transmission rack 24, and the clamping gear 25 is meshed with the transmission rack 24; in order to limit the rotation of the built-in threaded rod 21 and prevent the built-in threaded rod 21 from rotating with it when the clamping screw 23 rotates, positioning sliders 22 are fixed on both sides of the built-in threaded rod 21, and the positioning sliders 22 are slidably connected to the storage rack 2.

[0029] When working, first, the cover plate 3 is rotated around the driving shaft 12 through the handle 6. When the driving shaft 12 rotates, it drives the driving gear 13 to rotate at the same time. When the driving gear 13 rotates, it drives the transmission rod 15 fixed to the driven gear 14 through the driven gear 14 meshing with it to rotate at the same time. When the transmission rod 15 rotates, it drives the transmission gear 10 fixed to the transmission rod 15 to rotate, thereby driving the bidirectional screw 7 to rotate simultaneously through the transmission chain 11 and the transmission gear 10 fixed to the bidirectional screw 7. When the bidirectional screw 7 rotates, it drives the movable base 8 threadedly connected to it to move along the axial direction of the bidirectional screw 7. When the movable base 8 moves, the storage rack 2 is driven to rise through the adjusting rod 9, so that the reagent bottle or test tube placed on the inside of the storage rack 2 can be taken out from the inside of the fixed rack 1. When the cover plate 3 is closed, the bidirectional screw 7 is driven to rotate in the direction of the rotation, thereby storing the storage rack 2 inside the fixed rack 1. Through the coordinated structural design of the fixing frame 1, storage rack 2, drive shaft 12 and lifting assembly, when the cover plate 3 is opened, the storage rack 2 can be driven to move upward by the lifting assembly, so that the test tubes or reagent bottles placed inside the positioning holes 4 and the placement grooves 5 can be moved out from the inside of the fixing frame 1, thereby facilitating taking them out. At the same time, when the cover plate 3 is closed, the storage rack 2 is driven to move to the inside of the fixing frame 1, thereby effectively shielding and sealing the reagents in the storage rack 2, improving the convenience of operation and enhancing the practicality of the device.

[0030] When the test tube or reagent bottle is placed from the positioning hole 4 to the direction close to the placement groove 5 until it contacts the drive plate 17, the drive plate 17 will be squeezed, causing the drive plate 17 to move in the direction close to the telescopic spring 18. When the drive plate 17 moves, the drive frame 20 is driven to move at the same time by the connecting rod 19. When the drive frame 20 moves, the clamping gear 25 engaged with the transmission rack 24 drives the clamping screw 23 fixed to the clamping gear 25 to rotate. When the clamping screw 23 rotates, the built-in threaded rod 21 threadedly connected to it is driven to move along the axial direction of the clamping screw 23, thereby driving the clamping plate 16 to move away from the drive frame 20 when the built-in threaded rod 21 moves, and then the test tube or reagent bottle is clamped and fixed by the relative movement of the two clamping plates 16. Through the structural design of the clamping assembly, when the test tube or reagent bottle is placed inside the positioning hole 4 and the placement groove 5, its own weight can be used as a driving source to clamp and fix itself, thereby effectively avoiding shaking that causes damage to the test tube or reagent bottle, thereby improving the stability of the device.
