摘要：An omnidirectional adjustment-oriented positioning device of an office chairarmrest includes two parallel inner links pivotally connected between an armrest

rotation fixing unit and a rotation base. The inner links are enclosed in outer links to form

a parallel four-link swing link component. The rotation base is axially disposed at a pad.An armrest component capable of horizontal rotation and displacement is disposed atthe armrest rotation fixing unit. Inner and external wheel components with bevel gearsmeshing with each other are disposed between upper ends of the outer links and thearmrest rotation fixing unit. Positioning gears which mesh with each other are disposed atthe armrest rotation fixing unit. A positioning wheel is mounted at the armrest rotationfixing unit and rotatable such that a rotation component for rotating the inner wheelcomponent abuts against the inner wheel component and thus drives the positioningwheel to move outward.
