Containers of different specifications can be clamped and fixed to avoid the container shifting from the top of the body 301 during heating and stirring.

[0027] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0028] When the magnetic heating stirrer starts to be used, the user selects a corresponding container according to the experimental needs, and then puts the stirrer into the container. Then, the user pulls the second slide plate 406 in the clamping mechanism 4 forward. When the second slide plate 406 moves, the gear 404 can be driven to rotate, thereby driving the first slide plate 405 to slide backward. When the first slide plate 405 and the second slide plate 406 move in opposite directions, the support plate 407 can be driven to expand outward, thereby driving the clamping block 408 to open outward through the support plate 407. After opening the clamping block 408, the user places the container containing the solution and the stirrer on the top of the body 301 in the main body 3 of the magnetic heating stirrer. After placing the container, the user cancels the pulling of the second slide plate 406. The resilience generated by the contraction of the spring 412 can drive the telescopic rod 411 to reset, thereby driving the first slide plate 405 and the second slide plate 40 6 is reset at the same time, so that the container placed on the top of the body 301 can be centered and straightened, and the container can be clamped and fixed, and then the user loosens the fastening bolts 310 threadedly connected to the inside of the sliding tube 307 and the support tube 308, and can adjust the position of the cross bar 309, so that the bottom end of the temperature measuring rod 311 can be inserted into the inside of the container, and then the user re-tightens the fastening bolts 310 to fix the cross bar 309. Through the operation of the body 301, the solution inside the container can be heated and stirred. By setting the baffle 304, when the solution overflows from the inside of the container, it can be enclosed to prevent the solution from corroding the body 301. When it is necessary to clean the solution accumulated inside the baffle 304, it is only necessary to pull out the clamping plate 305 from the left side of the baffle 304 to facilitate the discharge of the solution and the cleaning of the top center of the body 301.
