Abstract: A hook for adjusting versatile widths has a body and a gasket. The body has a base and a hook body. The hook body is disposed on the base. The gasket has a hole and a plurality of protruding structures. The protruding structures are disposed around the hole. The different thicknesses of the protruding structures correspond to the different peripheral positions of the hole. The hook body penetrates through the hole of the gasket, and the gasket is able to rotate on the hook body.

Abstract: A reusable hanging device includes: an adhesion layer, a plate layer, and a hook body. Wherein, the adhesion layer is a low stickiness soft plastic made of a thermoplastic elastomer composite material, and it is vacuum-absorbed onto a smooth surface of a wall or a smooth surface of a wall having tiny bumps, by means of the super strong friction force produced on the smooth surface of a wall by the atmospheric pressure. The plate layer is made of hard material, formed integrally on a surface of the adhesion layer. And the hook body is also made of hard material, formed integrally on a surface of the plated layer. In application, the adhesion layer is absorbed onto a smooth surface of a wall by vacuum, the super strong friction force thus produced enables the hook body to hang object of 0˜112.6 kgf.
