[0029] The implementation principle of a lifting device for decorating a ceiling in an embodiment of the present application is as follows: The fixing plate 1 is in contact with one side of the wall in the decorated room. When installing the ceiling, the device is moved to one side of the indoor wall, at the bottom position of the ceiling. Then, the motor 4 is started as the power to drive the threaded column 5 on one side to rotate. The threaded column 5 on one side drives the threaded column 5 on the other side to rotate synchronously through the connecting belt 6. Immediately, the threaded column 5 drives the sliding block 8 to descend through the threaded ring 7. The sliding block 8 drives one end of the connecting plate 10 to descend through the first fixing rod 9. The other end of the connecting plate 10 drives the pedal 12 to rotate around the fixed ring 14 as a fulcrum under the traction of the rotating rod 13. During the rotation of the pedal 12, the pedal 12 drives the fixed ring 24 to move through the base. The fixed ring 24 drives the second ladder 22 to rotate around the fifth fixing rod 21 as a fulcrum through the sixth fixing rod 23. The fifth fixing rod 21 drives the fourth fixing rod 19 to move through the connecting plate 20. The fourth fixing rod 19 drives the first ladder 18 to rotate around the second fixed ring 16 as a fulcrum under the traction of the third fixing rod 17. When the pedal 12 rotates 90 degrees and lies flat, the first ladder 18 and the second ladder 22 extend into a straight line under the stretching of the pedal 12. At this time, the staff can first place the installation tools and ceiling materials on the pedal 12, and then drive the ceiling to move upward through the second ladder 22 and the first ladder 18.
