The tip 33 in the top rod 31 can be pressed against the top of the ice sample under the action of the elastic part 40, so that the tip 33 is inserted into the ice sample to realize the fixation of the top of the ice sample. Because the rotating body 32 can rotate relatively to the ejector rod 31, the rotating body 32 can rotate along with the ice sample in the rotating process of the ice sample, so that the relative rotation between the tip 33 and the ice sample is avoided, and the ejector pin can be ensured to tightly abut against the ice sample in the whole processing process.

The top rod 31, the rotating body 32 and the tip 33 are coaxial.

The top plate 13 of the frame 10 is movably provided with a top rod 31, and the top plate 13 is provided with a hole for moving the top rod 31. One end of the elastic member 40 is connected to the top end of the jack 31, and the other end of the elastic member 40 is connected to the top plate 13.
