This threaded hole 24 is a blind hole and partially passes into a center of the convex cylinder 22. When the threaded hole 24 is inter-engaged with the bolt 12, an abutting and fixing function can be formed. In addition, a plurality of teeth 25 are formed at an outer peripheral edge of the circular ring 23, whereby a sliding-off phenomenon during rotating procedure can be prevented.
The pad body 30, possessing vibration-absorbing and slide-resistant functions, is made of rubber material or is a magnetic element made of magnetic material. In this preferred embodiment, the pad body 30 is a circular ring accommodated in a space enclosed by the convex cylinder 22 and the circular ring 23 and is interconnected by adhering to the plate 21 via an adhesive (not shown in the figures). A side face of the pad body 30 remote from the plate 21 is convexly exposed to an outside of the side face of the circular ring 23 (as shown in FIG. 3), whereby this pad body 30 is contacted with the supporting surface to achieve a vibration absorption, glide resistance or magnetic adsorption.
Please refer to FIG. 2 and FIG. 3, respectively showing a perspective explosive view and an assembled illustration of the footpad structure according to another embodiment of the invention. In this preferred embodiment, the replaceable footpad structure further includes a metallic plate 40, which is accommodated in the space enclosed by the convex cylinder 22 and the circular ring 23 and is inter-connected by adhering to the plate 21 via an adhesive, while the pad body 30 is also interconnected by adhering to the metallic plate 40 via an adhesive, by the interconnection of both of which a magnetic loop operation is formed, which has a superior effect of magnetic adsorption. The side faces of this pad body 30 and the metallic plate remote from the plate 21 are exposed to the side face of the circular ring 23 (as shown in FIG. 3) and are arranged by flushing with each other.
