The magnetic snap-fit ​​between the cylindrical magnetic block 303 and the inside of the magnetic hole 306 is utilized to improve the limiting and fixing stability of the reserved block 305 after sliding.

[0037] In addition, the bottom end of the support leg 5 is fixedly connected with an anti-skid pad 8, and the bottom end of the anti-skid pad 8 is provided with anti-skid grooves. The anti-skid pad 8 with anti-skid grooves is used to increase the contact friction between the bottom end of the support leg 5 and the desktop, thereby improving the stability of the base 4.

[0038] The working principle and use process of the utility model are as follows: first, the base 4 is placed at a suitable position, and the anti-skid pad 8 with anti-skid patterns is used to increase the contact friction between the bottom of the support leg 5 and the desktop, thereby improving the stability of the base 4, and then the power cord is connected, and then the cover 1 is opened, and a suitable metal bath module 9 is selected according to the diameter of the test tube to be placed, and then the metal bath module 9 is placed in the heat preservation cover 2, and then the corresponding test tube is inserted into the test tube slot at the top of the metal bath module 9, and then the cover 1 is closed;

After that, after the cam 601 and the driving block 608 rotate away, the elastic force of the reset spring 605 is used to make the sliding block 606 slide and drive the substrate 7 to return to its original position, and then the sliding block 606 slides back and forth to drive the substrate 7 to slide back and forth, so as to realize the oscillating heating of the test tube placed inside the metal bath module 9, so that the contents of the test tube are heated quickly and evenly, and local overheating is avoided to cause the solidification of part of the contents, which causes the inconvenience of its use;

[0041] When the operation is completed or not in use, the protective plate 302 is pushed again to completely cover the touch screen 10, and another set of magnetic blocks 303 are used to engage with the magnetic holes 306 to achieve limited fixation of the protective plate 302 after sliding. The touch screen 10 can then be shielded and protected by the protective plate 302 to prevent the user from accidentally touching it and affecting the experimental heating, or from scratching or damaging the surface of the touch screen 10 due to external forces when not in use.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
