Description

Technical Field

The structure of this design forms a certain spatial area by adjusting the distance between the mounting piece and the vertical bar, and locks the building object therein. Even if the building hanging basket shakes, it only causes a small range of shaking of the object, and will not change its center. It has high safety, and is particularly provided with a connecting piece to further divide the spatial area. Although this type of lifting structure can prevent objects from shaking, it is lacking in adjusting the accommodation space. Since this type of lifting structure only limits the workpiece through a limit rod, when large or irregular objects need to be transported, the limit rod not only affects the placement of the workpiece, but also reduces the accommodation space of the lifting structure.
