In this way, the support columns 104a will be arranged in a staggered manner in sequence, rather than being completely stacked together. The pipe hole 104a-11 above will not be blocked in the contracted state, and they will not separate from each other in the extended state.

[0041] Preferably, a plurality of second support columns 104a-2 are provided and arranged in a staggered manner in sequence.

[0047] During use, the construction worker pushes the construction scaffold to the target position and presses the telescopic rod button 104c-3 on the four telescopic bases 104c, so that the base 104c-4 lifts the universal wheel 104b under the extension force of the telescopic rod 104c-2. At this time, the four universal wheels 104b are completely suspended, and the construction scaffold is supported by the four telescopic bases 104c, effectively avoiding the safety hazard that the universal wheels are locked and still unable to maintain stability on a slope or bumpy road surface; then, the construction worker climbs onto the standing board along the side ladder 103 and, according to factors such as his own height, first presses the limit rod button 101b-4 at the appropriate height to make the limit rod 101b-3 extend, and then pulls up the movable baffle 102b above the triangular prism block 101b-2 at the corresponding position. The convex block of the movable baffle 102b will be placed above the triangular prism block 101b-2 to achieve fixation, which is more convenient for the construction worker to carry out construction operations on the premise of ensuring the safety of the construction worker himself; finally, the construction worker presses the switch of the air pump 104d-1 according to the target height to inflate the airbag 104d-4, so that the support column 104a rises in stages under the pushing action of the air pressure. After the standing board 101a slowly rises to the appropriate height, the switch of the air pump 104d-1 is turned off, and the construction worker can start construction operations. After the construction worker completes the construction operations, rotate and open the deflation valve 104d-21 on one side of the rigid pipe 104d-2, and the air in the airbag 104d-4 is pressed out under the action of gravity. After the standing board 101a slowly descends to the initial position, the deflation valve 104d-21 is tightened again; then, press the limit rod button 101b-4 at the corresponding position on the L-shaped side column 101b again to make the limit rod 101b-3 retract, and the movable baffle 102b automatically falls to the initial position under the action of gravity, and the construction worker can return to the ground along the ladder 103; finally, the construction worker presses the telescopic rod button 104c-3 on the four telescopic bases 104c again, so that the base 104c-4 rises above the universal wheel 104b, and the construction worker can push away the construction scaffold.
