Furthermore, an anti-skid rubber pad is adhered to the handle, so that a user is prevented from being grabbed and falling off in the operation process and injuring the skin of the hand.

Furthermore, the anti-skidding rubber pads are adhered to the bottom of the limiting rod, the limiting rod is screwed to the surface of the sample, and the anti-skidding rubber pads can be tightly pressed on the surface of the sample, so that the vertical position of the sample can be better fixed in the polishing process.

Furthermore, the anti-skidding rubber pads are adhered to the inner sides of the sample clamping pieces, and the anti-skidding rubber pads on the inner sides of the sample clamping pieces are tightly attached to the outer edges of the samples, so that the horizontal positions of the samples can be better fixed in the polishing process.

When a sample is polished, the limiting rod is firstly screwed, the center of the sample is aligned to the center of the clamp, and the sample is moved in the vertical direction to select a proper height. And moving the four limiting bolts along the strip through holes at the cross-shaped end parts of the clamp until the anti-skid rubber pads on the inner sides of the sample clamping pieces are tightly attached to the outer edges of the sample, and screwing the limiting bolts to fix the horizontal position of the sample. And then the limiting rod is screwed down to enable the anti-skid rubber mat at the bottom of the limiting rod to be tightly attached to the surface of the sample, so that the vertical position of the sample is fixed. After the sample is fixed, the handle can be held by hand to polish.

The utility model has the beneficial effects that: the tool provided by the utility model has the advantages of simple structure, convenience in operation and low manufacturing cost, avoids potential safety hazards of polishing of a hand-held sample, can apply pressure to the gravity center of the sample, can observe a circular level gauge to adjust the polishing angle in the polishing process, and can more easily achieve the flatness and uniformity required by experiments.
