Further, the cross section of the sleeve is of a 'return' structure.

Furthermore, sliding base and sleeve are fillet weld fixed, test bench and fixed strip are fillet weld fixed.

Furthermore, the arc-shaped groove can be processed according to the diameter of the rod-shaped test sample, and the processing diameter of the arc-shaped groove is not smaller than the diameter of the tested sample, so that the opening part can be attached to the surface of the cylindrical test sample.

Further, the device is suitable for non-magnetic materials, such as stainless steel pipes in high-parameter boilers, non-magnetic high-temperature bolts and the like.

Further, the cylindrical test samples are rod-shaped materials with small diameters, such as high-temperature bolts, superheater tubes in boilers, reheater tubes, economizer tubes, water wall tubes and the like.

Compared with the prior art, the utility model, have following advantage and effect: by adjusting the horizontal positions of the fixed base and the sliding base and the vertical positions of the sleeve and the test bed, the open hole of the test bed can be tightly attached to a tested sample, a large-area stable platform is provided for the portable metallographic microscope, the metallographic test with high requirements on stability and planarity can be completed, and the field photographing effect and the test efficiency of the metallographic test are improved; meanwhile, the bracket is suitable for rod-shaped materials and nonmagnetic materials with small diameters and has a wider application range.
