Abstract
A hinge has a base, a first bracket, a second bracket and a vertical-angular-positioning assembly. The first bracket is mounted pivotally on the base. The second bracket is mounted pivotally on the base. The vertical-angular-positioning assembly is mounted on the base, positions the second bracket in specific angular positions relative to the base and has positioning rings and a sleeve. The sleeve is mounted on the base and prevents dust from accumulating in the sleeve. With the arrangement of the sleeve, the hinge is durable.
