[0014] 1. This utility model features an adjustable structure. When a container is placed on top of a heating plate, rotating a hand-operated lever (threaded to a movable frame) causes the movable frame to move up and down within a fixed block. This movement lowers two sets of movable frames to the outside of the container, while the stirring frame descends to the inside. Rotating a threaded rod (threaded to two sets of movable frames) causes the two sets of movable frames to move towards each other. The movable frames slide on a guide rod, causing a roller to conform to the container, thus fixing the container's position on the heating plate. Keep the container centered on the heating plate, place the magnetic stir bar inside the container, and the magnetic stir bar will be magnetically connected to the magnetic block through the container and heating plate. Starting the first motor will drive the magnetic block to rotate, which in turn drives the magnetic stir bar to rotate inside the container, stirring the reagent inside the container. The heating plate can heat the reagent inside the container to maintain a constant temperature. Starting the second motor will drive the stirring rack to rotate, and the rotation of the stirring rack can further agitate the reagent inside the container to fully and continuously remove gas. No manual stirring is required, saving manpower and improving work efficiency.
[0015] 2. This utility model, by setting up a collection structure, allows the hand-operated lever to be reversed after stirring to raise the stirring rack. After the container is removed from the second motor, the hand-operated column can be rotated, which drives the cover plate to rotate on the top surface of the controller via the rotating block. The cover plate can block the upper side of the heating plate, preventing liquid dripping from the stirring rack from contaminating the heating plate, keeping the heating plate clean, and ensuring the heating effect of the heating plate on the reagent.

[0025] An adjustment structure 2 is installed on the base 1. The adjustment structure 2 includes a fixed block 21, which is fixedly installed on the rear wall of the base 1. A movable frame 22 is inserted into the upper end of the fixed block 21. A hand-rotating rod 23 is movably installed on the inner side of the fixed block 21 through a bearing. A guide rod 24 is fixedly connected to the end of the movable frame 22. Two sets of moving frames 25 are slidably installed on the outer side of the guide rod 24. Two sets of rollers 26 are rotatably connected to the end of the moving frame 25. A threaded rod 27 is movably installed on the end of the movable frame 22 through a bearing. A second motor 28 is fixedly installed on the end of the movable frame 22. A stirring frame 29 is fixedly connected to the output end of the second motor 28. Through mechanical stirring and constant temperature heating, the gas is fully and continuously expelled, eliminating the need for manual stirring, saving manpower, improving work efficiency, and being applicable to various experimental scenarios. It can be flexibly used for stirring solutions of different specifications and can also be used for dissolving solid reagents, saving costs.
[0026] Furthermore, a collection structure 3 is installed on the controller 11. The collection structure 3 includes a cover plate 31, which is movably installed on the front side of the top of the controller 11. A rotating block 32 is integrally formed on the top surface of the cover plate 31, and a hand-rotating column 33 is fixedly connected to the bottom surface of the cover plate 31. The cover plate 31 can block the upper side of the heating plate 18 to prevent liquid dripping from the stirring rack 29 from contaminating the heating plate 18, keeping the heating plate 18 clean, and ensuring the heating effect of the heating plate 18 on the reagent.
[0027] Furthermore, the magnetic stir bar 15 and the magnetic block 17 cooperate with each other, and the magnetic block 17 can drive the magnetic stir bar 15 to rotate through the heating plate 18 and the container 14.
[0028] Furthermore, the hand-operated rod 23 passes through the movable frame 22 and is threadedly connected to the movable frame 22, and the threaded rod 27 passes through the two sets of movable frames 25 and is threadedly connected to the movable frames 25. The rotation of the hand-operated rod 23 can drive the movable frame 22 to move within the fixed block 21, thereby adjusting the position and height of the movable frame 25 and the stirring frame 29. Rotating the threaded rod 27 can drive the movable frame 25 to move, thereby adjusting the position between the roller 26 and the container 14.
[0029] Furthermore, the two sets of movable frames 25 are located on both sides of the second motor 28, and the stirring frame 29 is located on the upper side of the middle of the heating plate 18.

[0031] Working principle: Before use, place the container 14 on the top surface of the heating plate 18. Rotate the hand crank 23, which is threadedly connected to the movable frame 22. The rotation of the hand crank 23 causes the movable frame 22 to move up and down within the fixed block 21. The movement of the movable frame 22 causes the two sets of moving frames 25 to descend to the outside of the container 14, and the stirring frame 29 to descend to the inside of the container 14. Rotate the threaded rod 27, which is threadedly connected to the two sets of moving frames 25. The rotation of the threaded rod 27 causes the two sets of moving frames 25 to move towards each other. The moving frames 25 slide on the guide rod 24, which can cause the roller 26 to fit against the container 14 to fix the position of the container 14 on the heating plate 18. Keep container 14 centered on heating plate 18, place magnetic stir bar 15 inside container 14. Magnetic stir bar 15 will be magnetically connected to magnetic block 17 through container 14 and heating plate 18. Starting the first motor 16 can drive magnetic block 17 to rotate, which in turn drives magnetic stir bar 15 to rotate inside container 14, stirring the reagent inside container 14. Heating plate 18 can heat the reagent inside container 14 to maintain a constant temperature. Starting the second motor 28 can drive stirring rack 29 to rotate. The rotation of stirring rack 29 can further agitate the reagent inside container 14 to fully and continuously remove gas, eliminating the need for manual stirring, saving manpower and improving work efficiency.
[0032] After stirring is complete, the hand crank 23 can be reversed to raise the stirring rack 29. After removing the container 14 from the second motor 28, the hand crank column 33 can be rotated. The hand crank column 33 drives the shield 31 to rotate on the top surface of the controller 11 via the rotating block 32. The shield 31 can block the upper side of the heating plate 18 to prevent liquid dripping from the stirring rack 29 from contaminating the heating plate 18, keeping the heating plate 18 clean and ensuring the heating effect of the heating plate 18 on the reagent.
