They are used in conjunction with scaffolds to fix the upper and lower supports, and have the advantages of convenient operation and high recycling rate. The adjustable top support consists of three parts: a tray, a threaded rod, and an adjustment nut. Generally, the adjustment nut is a nut with two end ears extending out. During on-site construction, the operator uses a hammer to hit the end ear to rotate the adjustment nut around the threaded rod to adjust the extension length of the supporting threaded rod and drive the tray up and down. However, there are problems: (1) The hammer will produce noise, increasing the pollution of the construction environment; (2) The operator uses a hammer to hit, forcing the nut to rotate, and the accuracy of driving the tray up and down is not enough, resulting in multiple positive and negative repeated knocking phenomena, and low work efficiency.
