[0080] Working principle: when the device needs to be used, the staff pushes the driving device to drive the universal wheel 24 to roll and move the device as a whole to the working position. The staff presses the jack 32 with a lever, and the jack 32 lifts the device as a whole. At this time, the staff toggles the lever 27 to drive the universal wheel 24 to move, and the universal wheel 24 drives the T-shaped block 25 to slide in the T-shaped slot 23. At the same time, the T-shaped block 25 squeezes the spring 1 26 to compress the spring 1 26. When the lever 27 is flush with the straight edge of the L-shaped slot 34, the connecting block 22 is driven to slide upward under the tension of the tension spring 21. The connecting block 22 drives the universal wheel 24 to slide into the fixed foot 13, thereby shrinking the universal wheel 24, and then the device is lowered as a whole through the jack 32. The bottom surface of the fixed foot 13 is in direct contact with the bottom surface, so that the stability of the device is enhanced when it is used. The staff presses the ratchet 31 to squeeze the spring 2 30 to disengage the ratchet 31 from the ratchet 28, and starts the motor 2 17 to drive the threaded rod 2 18 to rotate. The threaded rod 2 18 The threaded sleeve 8 is driven to slide upward, and the threaded sleeve 8 drives the installation rod 9 to slide upward, and the installation rod 9 drives the crossbeam 19 to move upward, and the crossbeam 19 drives the protective net 11 to slide out of the drum 10, and the protective net 11 drives the drum 10 to rotate until the height of the protective net 11 reaches a suitable working position for the staff, and the ratchet 31 is released. The device drives the ratchet 31 to rotate under the elastic force of the spring 2 30, so that one end of the ratchet 31 is against the teeth of the ratchet wheel 28, thereby preventing the protective net 11 from spontaneously sliding out of the drum 10, and the position of the protective net 11 is fixed, and the counterweight block 33 is placed on the top surface of the base 1. The staff goes up to the workbench 2 through the stairs 35 to prevent the device from overturning when the staff goes up to the workbench 2, and the motor 16 is started to drive the threaded rod 15 to rotate. The threaded rod 15 drives the two threaded sleeves 214 to slide in opposite directions, thereby driving the two connecting rods 5 to close, and the workbench 2 is lifted to the working position, and the staff can work again.
