In this embodiment, to ensure the convenience of detaching the heating plate 21 and the cover plate 22, the slider 43 is connected to the end of the supporting block 1 through the first connecting block 45. In other embodiments, the fixing plate 44 and the first connecting block 45 may not be used, and the cover plate 22 may be directly fixed to the sliding block 43, or a sliding rod and sliding sleeve structure may be used instead of the sliding rail 42 and the sliding block 43.

Because supporting shoe 1 has certain length and slider 43 passes through the end connection of first connecting block 45 with supporting shoe 1, can lead to whole supporting shoe 1 focus to deviate from slider 43 far away, the easy unstability phenomenon that appears. In order to ensure the stability of the loading mechanism 2, as shown in fig. 7, in the present embodiment, the test tube holder 231 is provided with a roller 47, the roller 47 is connected with the test tube holder 231 through a mounting bracket and a rotating shaft, the roller 47 can rotate on the slide rail 42 relative to the rotating shaft, meanwhile, the mounting position of the roller 47 is required to satisfy the support through the roller 47 and the slider 43, the distance between the two ends of the supporting block 1 and the mounting plate 41 can be kept equal, and the above arrangement can further improve the stability of the supporting block 1.
