[0002] In construction, adjustable brackets are the main accessories of scaffolding and must comply with relevant specifications. The screw rods of adjustable brackets currently designed are relatively long and have threads along the entire length. During on-site construction, due to the randomness of workers installing the adjustable brackets, the exposed length of the screw rods may be too long or the length of the adjustable bracket inserted into the vertical pole may be too short, exceeding the allowable values ​​in the specifications, resulting in the frame being unstable and shaking, thus causing safety accidents.

[0003] At present, a patent document with publication number CN208586888U discloses a safe adjustable bracket for scaffolding. Through the combined action of a screw, a vertical rod, a nut and a piston plate, the screw drives the bracket to perform stable height adjustment. At the same time, by making the lengths of the toothed part and the toothless part of the screw meet the requirements of the specification, the exposed length of the screw will not be too long or the length of the adjustable bracket inserted into the vertical rod will not be too short, so that the use of the adjustable bracket can easily meet the requirements of the specification and reduce the safety hazards caused by the randomness of the workers installing the adjustable bracket.
