s1, when the device needs to be used, the device is moved to a designated place through a pushing handle (22), then a control panel (10) enables a double-shaft motor (9) to drive two rotating shafts I (8) to rotate, the rotating shafts I (8) can drive rotating shafts III (37) to rotate through matching with bevel gears I (2) and bevel gears II (6), the rotating directions of the two rotating shafts III (37) are opposite to each other, the rotating shaft III (37) on the left side drives a fixed rod (3) and a universal wheel (5) on the left side to swing leftwards, the rotating shaft III (37) on the right side drives a fixed rod (3) and a universal wheel (5) on the right side to swing rightwards, and therefore the four universal wheels (5) can leave the ground, the bottom of a T-shaped plate (4) is in contact with the ground, and the stability of the device in use can be improved;
s2, the worm (11) is rotated through the handle (13), the worm (11) can drive the second rotating shaft (16) and the winding reel (18) to rotate through the matching with the worm wheel (17), the rope (23) can be wound through the winding reel (18), so that the rope (23) can pull the third fixing plate (19) leftwards, the first supporting plate (25) can be turned leftwards by the hinge (27) until the left side of the first supporting plate (25) is completely overlapped with the upper surface of the second supporting plate (26), the upper surface of the first supporting plate (25) is overlapped with the movable end of the telescopic rod (31), the telescopic rod (31) and the spring (32) are both compressed by the first supporting plate (25), the two racks (24) are butted together, and T-shaped sliding grooves in the first supporting plate (25) and the second supporting plate (26) are communicated together;
s3, the monitor body (20) and the display (14) are opened through the control panel (10), pictures shot by the monitor body (20) can be transmitted to the display (14), workers can know the conditions of crowds by watching the display (14), if information needs to be disclosed to the crowds, the contents needing to be disclosed can be transmitted to the display (14) through the control panel (10), then the motor (38) drives the gear (36) to rotate through the control panel (10), the gear (36) can drive the four fixing plates (33), the two U-shaped plates (34) and the display (14) to move upwards through the matching of the rack (24), the T-shaped sliding groove, the T-shaped sliding block 35 and the motor base (39), and therefore the height of the display (14) is increased so as to be convenient for the pedestrians to watch.
