Because graphite has good high-temperature resistance, electrical conductivity, thermal conductivity, lubrication, chemical stability and other properties, graphite products are widely used in metallurgy, chemical industry, electrical and other fields.

[0003] In the existing graphite product clamping and fixing, the graphite product is usually fixed by manual adjustment of the clamping tool. In this process, due to the limitations of manual adjustment, the clamp cannot effectively fix the graphite product completely, and there will be a gap between the clamp and the graphite product. Secondly, in a high-temperature environment, the stress concentration coefficient of the corner of the clamp is much higher than that of the flat or round corner area, which will cause local cracks in the graphite product in contact with the corner, and with the cycle of temperature or the continuous expansion of pressure, the graphite product will eventually collapse.
