And moving the cross bar connector on the other side to the same height, and fixing the height by using a fixing bolt. The cross rod is rotatably installed on the cross rod connector through threads, the rotating shaft is rotated clockwise, the rotating shaft drives the gear to rotate clockwise, the rack meshed with the gear rotates through the gear, the supporting rod extends upwards, and when the supporting rod rises to the required height, the height is fixed through the bolt.

Advantageous effects

Compared with the prior art, the method has the advantages that,

1. this adjustable scaffold frame clockwise rotates the pivot, and the pivot drives the gear, and with gear engagement's rack, through the rotation of gear, upwards extends, under the cooperation through pivot, gear and rack, the person of facilitating the use adjusts the bracing piece and reaches required height.

2. This adjustable scaffold frame through the rubber pad on the support base, under the effect of gravity, has strengthened the scaffold frame and to the land fertility of grabbing on ground, reduces the scaffold frame subaerial gliding risk.

3. This adjustable scaffold frame through the horizontal pole of fixed mounting between the horizontal pole connector, has strengthened the holistic stability of scaffold frame.
