Claim:
An outdoor umbrella, comprising: a stand, a rotatable shaft uprightly extended from said stand wherein a locker hole is transversely provided on an outer surface of said shaft, a foldable awning frame which supports a fabric thereon comprising a first supporting arm extended to a top of said shaft and a second supporting arm pivotally connected to said first supporting arm and arranged in such a manner that when said second supporting arm pivotally rotates toward to said first supporting arm, said foldable awning frame extends unfoldably; a pulley system mounted on said shaft for folding and unfolding said fabric; and an operation device comprising a tubular slider joint slidably mounted on said shaft in a vertical movable manner wherein said second supporting arm of said foldable awning frame is pivotally connected to said slider joint, a locking stopper fitted in said locker hole of said shaft in an inwardly movable manner, means for applying an urging pressure against said locking stopper to normally urge and retain said locking stopper extending into said locker hole so as to lock up said slider joint on said shaft, and a handle means for driving said locking stopper, in an outwardly movable manner, to move away from said locker hole so as to unlock said slider joint from said shaft, wherein said slider joint comprises a pair of parallel walls integrally and outwardly extended therefrom wherein a guiding slot is defined between said two parallel walls in such a manner that said locking stopper is slidably received in said guiding slot in a horizontal movable manner, wherein said means comprises a resilient unit having a resilient element which is disposed in said guiding slot and has one end coupled with said locking stopper while another end thereof biased against a bottom wall of said guiding slot, wherein said locking stopper has an enlarged head portion having a shape and size adapted to fittedly insert into said locker hole of said shaft and an elongated tail portion which is extended between said two parallel walls, wherein said resilient unit has a driving end urging against said locking stopper and an opposed end which is pivotally mounted to said two parallel walls, wherein said handle means comprises a curved operation handle integrally extended from said opposed end of said resilient element wherein said operation handle is arranged to pivotally drive said driving end of said resilient unit to bend outwardly, so as to move said head portion of said locking stopper away from said locker hole.
