There are two magnets 203, and there is a gap between the two magnets 203. The corresponding surfaces of the two magnets 203 are both N poles.

[0027] By utilizing the above structure, through the characteristic that the corresponding surfaces of the two magnets 203 are both N-poles, it can be known that a repulsive force will be generated between the two magnets 203, so that the two magnets 203 will restrain each other, so that the workpiece sample 12 can be effectively buffered when placed, thereby maintaining the overall stability of the device and avoiding the positioning effect affected by shaking.
