Abstract
A hinge includes a first connector which has a hollow pivotal sleeve with a channel penetrating therethrough, a coupling flap and a locating strip spaced from each other in a parallel relation and connected with two opposite edges of the channel respectively, a resilient tube pivotally received within and circumferentially biasing against the pivotal sleeve to produce a friction resistance force therebetween, two second connectors fastened to two opposite ends of the resilient tube, and a fastening element for holding the locating strip and the coupling flap closely together and adjust a space between the locating strip and the coupling flap to further regulate the friction resistance force. So the first connector may be positioned at any desired angle relative to the second connectors by means of the friction resistance force between the resilient tube and the pivotal sleeve.
