When the position of the scaffolding platform 4 is automatically adjusted, the user starts the bidirectional motor 5, and the bidirectional motor 5 drives the rotating rod 6 to rotate through the output end, and the rotating rod 6 drives the first bevel gear 7 to rotate, and the first bevel gear 7 meshes with the second bevel gear 8 to drive the second bevel gear 8 to rotate, and the second bevel gear 8 drives the transmission rod 9 to rotate, and the transmission rod 9 drives the first transmission disk 10 to rotate, and the first transmission disk 10 drives the traction rope 11 is moved through the second transmission disc 12, the third transmission disc 14 and the fourth transmission disc 15, so that the third transmission disc 14 and the fourth transmission disc 15 drive the moving plate 13 to slide upward inside the slide groove 26, and the moving plate 13 drives the mounting frame 17 and the connecting block 18 to move upward, and the connecting block 18 drives the scaffolding platform 4 to move upward, thereby automatically and quickly lifting the scaffolding platform 4. The traction rope 11 will be worn out after long-term use and needs to be replaced. The rotating block 163 is rotated through the anti-slip groove 24, and the rotating block 163 drives the clamping block 164 to move forward. The clamping block 164 releases the limit on the traction rope 11, and the traction rope 11 is removed for replacement.
