Data display device for intelligent block chain of oil and gas field and use method of data display device

The invention discloses a data display device for an intelligent block chain of an oil and gas field and a use method of the data display device. The data display device comprises a fixed transverse plate, T-shaped sliding ways, a mounting frame, an electric telescopic rod, a fixed sleeve, a display screen, a driving assembly and a positioning assembly, the T-shaped sliding ways are symmetrically formed in the fixed transverse plate, and T-shaped sliding blocks are slidably connected into the two T-shaped sliding ways. The display device is easy and convenient to operate and high in practicability, the mounting frame can be driven by the driving assembly to move on one side of the fixed transverse plate, so that the transverse position of the display screen is adjusted, the height of the display screen can be adjusted through the electric telescopic rod, the positioning assembly matches a connecting rod and a T-shaped rod for use, and the angle of the display screen can be adjusted, so that different use requ
