The hook device contains a base, at least a first wheel, a second wheel, a third wheel, and at least an elastic hook element. The base has a first wall and, extending respectively from two lateral edges of the first wall, a second wall and a third wall. The wheels are positioned on the walls, respectively. Along the edge between the first and second walls, an extension piece with a curved outer edge is extended for the configuration of the elastic hook element. The wheels are embedded in a first, second, and third grooves of a column, respectively. The base's three wheels, together with the corresponding configurations of separate grooves, enable the base to be reliably mounted on and moved along the column. The elastic hook element, with its elastic and buffering mechanism, provides multi-stage buffering and thereby is capable of withstanding a significant degree of wind impact.
