In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks and strata in a certain area. Conduct investigation and research work on geological conditions such as geology, structure, mineral resources, hydrology, and landforms.

In the process of geological exploration, sampling devices are often used. The so-called sampling device is to select a suitable sampling location in the area to be explored, and then insert the cylindrical sampling device into the ground to collect the soil, sand and gravel in the selected area. Or the regionally representative soil such as mud is taken away for testing. Sometimes due to geological reasons, it is not possible to drill a sample with a suitable diameter at one time, so a reaming device is needed to achieve the purpose.

Most of the existing reaming devices also use a cylindrical drill bit with a larger diameter, and its structure is not much different from that of the sampling device. When in use, due to the topography, the reaming part may not be able to match the previous drilling position. The coincidence of the axis centers will cause the reaming part to be deflected. Therefore, a reaming device that can work stably and meet the requirements of reaming is required.
