9. The method for using the display screen with the looseness warning function according to claims 1-8, wherein the method comprises the following steps: the method comprises the following steps:
1) When in use, the base (1) is moved to a designated position; a group of thread barrels (101) are rotated, and the two groups of thread barrels (101) are simultaneously rotated through a synchronous wheel (106) and a synchronous belt, so that the two groups of threaded rods A (102) drive a bottom plate (103) and an anti-skid pad (104) to move downwards, and the anti-skid pad (104) is attached to the ground; thereby fixing the base (1); placing a display screen shell (504) on the outer side of the connecting frame (501); the limiting plate A (502) is attached to the outer side of the display screen shell (504), and the outer side of the limiting plate B (506) is attached to the outer side of the connecting frame (501); the bolt piece (507) is screwed into the thread sleeve (505) through the fixing ring (601) and the round hole (503); so that the display screen shell (504) is fixed on the outer side of the connecting frame (501); the extrusion ring (508) is used for extruding the annular bag (602), so that gas or liquid in the annular bag (602) flows into the T-shaped pipe (603), the piston rod (604) and the piston plate (605) are lifted, the conductive block (6062) is separated from the conductive strip (6071), and the warning lamp (6072) is in a power-off state; when the bolt piece (507) is loosened, the spring piece drives the piston rod (604) to move downwards for resetting; so that liquid or gas in the T-shaped pipe (603) is squeezed into the annular bag (602) again, and the conductive block (6062) is in fit connection with the conductive strip (6071); the warning lamp (6072) and the storage battery (6061) form a passage; thereby the warning lamp (6072) warns the looseness of the bolt piece (507);
2) The display screen shell (504) is broken off, and the display screen shell (504) drives the connecting seat (204) to rotate, so that the control block (403) moves upwards through the bottom gear tooth structure; when the display screen shell (504) rotates to a specified angle, the spring piece drives the control block (403) to reset through the control rod (402), so that the gear tooth structure at the bottom of the control block (403) is meshed with the gear tooth structure at the top of the fixed block (203) again; thereby securing the display housing (504); when the heights of the display screen shell (504) and the display screen main body (509) need to be adjusted, the motor device is started to drive the worm A (209) to rotate, the worm A (209) drives the threaded rod B (206) to rotate through the worm wheel A (208), and the threaded rod B (206) drives the sliding column (201) to slide up and down, so that the height of the display screen main body (509) is adjusted; simultaneously, the threaded rod B (206) drives the double-ended screw rod (301) to rotate through the large conical gear (207) and the small conical gear (302); the double-headed screw (301) drives the two groups of sliding seats A (303) to move in opposite directions at the same time, so that the rotating plates (304) on the two sides of the sliding seat A (303) rotate in opposite directions at the same time, and the two groups of sliding seats B (305) drive the two groups of supporting plates (306) to move in opposite directions, so that when the height of the display screen main body (509) is higher, the larger the distance between the two groups of supporting plates (306) is, and the larger the supporting area is;
3) A group of transverse shafts (701) are rotated through a worm B (7010) and a worm wheel B (709), and conical gears A (702) at two ends of the transverse shafts (701) and conical gears B (706) at the bottom ends of vertical shafts (705) drive the two groups of vertical shafts (705) to reversely rotate; meanwhile, the vertical shaft (705) drives the other group of transverse shafts (701) to reversely rotate through the top conical gear B (706) and the conical gear A (702), so that the two groups of shielding plates A (703) and the two groups of shielding plates B (707) simultaneously rotate outwards or inwards; thereby enabling the display range of the display screen main body (509) to be controlled.
