Cantilever umbrella

Abstract

A cantilever umbrella includes a canopy, a base, and an upright pole. The upright pole is disposed on the base. A locking block is fixedly disposed on the upright pole. A fixed rod, a first cantilever arm, and a second cantilever arm are disposed on the locking block. A connector on the first cantilever arm is connected to a protruding portion on the second cantilever arm through a second screw. After the first cantilever arm and the second cantilever arm are dismounted, a size of a transportation case can be reduced when the cantilever umbrella is packaged for transportation, and therefore, costs are reduced. When the first cantilever arm and the second cantilever arm slide in the locking block and a locking sliding sleeve, an angle of the canopy is adjusted with sliding of the first cantilever arm and the second cantilever arm.
