8 and the second supporting rod 23 and, the scaffold is more stable to use by matching with the limiting device 4 and the latch 3, when the height of the carrier plate 10 needs to be reduced, the limiting rod 42 is pulled to be separated from the latch 3, the mounting block 2 can be moved downwards, after the completion, the limiting rod 42 is inserted into the latch 3 again to be meshed with the latch 3 to fix the position of the mounting block 2, and further to fix the position of the carrier plate 10, so that the height of the scaffold can be adjusted to meet the use requirement, when the scaffold needs to be disassembled, the carrier plate 10 is taken down, the adjusting rod 504 is pressed to move towards the inside of the connecting shell 501, when the scaffold cannot move, the adjusting rod 504 is rotated in the forward direction to drive the first bevel gear 503 to rotate and further drive the four second bevel gears 507 to rotate, the second bevel gears 507 drive the screw rod 506 to rotate and further drive the moving block 508 to move towards the second bevel gear 507, so that the J-shaped fixing rod 509 leaves the fixing groove 7, when the scaffold needs to be assembled, the connecting shell 501 is inserted into the connecting piece 6, the adjusting rod 504 is pressed to move into the connecting shell 501, the return spring 510 is extruded to deform to generate acting force, when the scaffold cannot move, the adjusting rod 504 rotates reversely to drive the first bevel gear 503 to rotate so as to drive the four second bevel gears 507 to rotate, the second bevel gears 507 drive the lead screws 506 to rotate so as to drive the moving block 508 to move in the direction away from the second bevel gears 507, so that the J-shaped fixing rod 509 enters the fixing groove 7, when the adjusting rod 504 is released, the return spring 510 loses the limit release acting force to drive the adjusting plate 502 to move in the direction away from the connecting piece 6, so that the J-shaped fixing rod 509 is inserted into the fixing groove 7 to fix the connecting piece 6, the connecting piece 6 is respectively connected with the corresponding connecting device 5 to realize the assembly between the first supporting rod 8, the second supporting rod 23 and the upright post 1, after the assembly is completed, the fixed inserting rod 11 on the carrier plate 10 is inserted into the fixed hole 9 to realize the installation of the carrier plate 10 and further realize the assembly of the scaffold, after the scaffold is disassembled, the first fixture block 16 can be inserted into the first clamping piece 15 to realize the combination between the two upright posts 1, when the first fixture block 16 enters the clamping shell 151, the convex block at the top end of the first fixture block 16 and the bottom end of the pull rod 153 slide relatively to push the pull rod 153 upwards to enable the pull plate 154 to move upwards to compress the return spring 155 to deform to generate an acting force, when the convex block moves to the left side of the pull rod 153, the return spring 155 releases the acting force to drive the pull plate 154 to move downwards so as to drive the pull rod 153 to move downwards to clamp the convex block 16 to realize the fixation of, thereby realize fixing between first fixture block 16 and the first joint spare 15, can fix between a plurality of first fixture blocks 16 and the first joint spare 15 and realize the equipment between four stands 1 after the scaffold frame is dismantled, make them classify and concentrate, can find four stands 1 fast when convenient next time equipment, avoid the dispersion to place the condition that leads to losing simultaneously and appear, the same reason can be with the combination between two first bracing pieces 8 and the combination between two second bracing pieces 23.
