[0037] The sample slot 2 is located on the front side of the frame 1 and is fixed to the top end of the lifting mechanism 3. The sample slot is composed of a bottom sample plate 21, a first clamping plate 22, a second clamping plate 23, a left baffle 28, and a right baffle 29. Among them, the first clamping plate 22 is fixed to the sample plate 21 by screws at the lower part; the second clamping plate 23 is an adjustable movable clamping plate. Two circular guide shafts 24 and a screw rod 25 are installed at the lower front outer side of the bottom sample plate 21 for supporting the movable baffle. The front second clamping plate 23 is inserted through two corresponding orifices on the front side of the bottom sample plate 21 and is fixedly connected to the bottom sample plate through the screw rod 25 by a wing nut 26. According to the diameter of the sample, the wing nut is adjusted to fix the sample in the sample slot so as not to slide.
