The supporting mechanism comprises four threaded holes. By arranging a driving motor and a threaded rod, the threaded sleeve and the slide plate can be driven to rise in the slide groove when the driving motor rotates, so as to conveniently drive the mounting rod and the display to rise and fall in the mounting box. It cannot be put away after use, cannot be quickly ejected before use, occupies a large space, has no auxiliary dust cleaning, cannot assist in cleaning the surface before each use, and is prone to dust accumulation on its surface after long-term use. Therefore, a technician in this field provides a flameproof and intrinsically safe operating display screen for mining to solve the problem that it cannot be put away after use, cannot be quickly ejected before use, occupies a large space, has no auxiliary dust cleaning, cannot assist in cleaning the surface before each use, and is prone to dust accumulation on its surface after long-term use.
