The wheel 405 will contact the ground at this time, and the rotation of the pulley 405 will rotate on the ground with the help of the other four universal wheels 2. At this time, the support frame 1 starts to move horizontally and linearly. When the support frame 1 moves to the unpainted wall position, the construction personnel standing on the support plate 3 can stop turning the handle 413 and then release the insertion rod 415.

The fixed frame 403 will drive the pulley 405 to separate from the ground. When the screw rod 52 rotates, the screw rod 52 drives the adjusting wheel 54 to move. When the pulley 405 moves upward with the driven wheel 407, the belt 412 can be kept in a tightened state with the help of the adjusting wheel 54, so as to avoid the belt 412 from loosening and falling off the driving wheel 410 and the driven wheel 407 when the pulley 405 is adjusted upward. When the pulley 405 is separated from the ground, the position of the support frame 1 can be adjusted at will with the help of the universal wheel 2.
