The invention discloses a cantilever parasol with reduced maintenance workload. When the reel mechanism requires maintenance, one only needs to detach the reel housing from the inclined rod, without a need to perform a separate disassembly operation to the cord spool assembly or a need to change a connection relationship between the inclined rod and the post, avoiding difficulty in re-assembling the inclined rod.

The cantilever parasol includes a post, an inclined rod and a reel mechanism. The reel mechanism includes a reel housing is detachably connected with the inclined rod, and a cord spool assembly is rotatably installed in the reel housing and located on an outer side of the inclined rod. One end of the inclined rod is connected with the post, the inclined rod is provided with a cord hole, and a cord is passed through the cord hole and connected with the cord spool assembly.

A tilt device for an umbrella is a guide track assembly disposed in one of a first tilt member and a second tilt member. The guide track assembly has a first guide track member and a second guide track member. An enclosed guide track is within the guide track assembly. The guide track assembly is slideably received within the first tilt member. A driver that has an upper portion disposed in the second tilt member and a lower portion. The lower portion is disposed in the enclosed guide track. The enclosed guide track is configured to guide movement of the lower portion of the driver within the first tilt member. Movement of the driver causes the second tilt member to tilt relative to the first tilt member. The guide track assembly includes an open channel forming a part of a cord channel through the tilt device.

A umbrella sliding assembly, includes a post, a slider, a first pulley, a second pulley and a fixing piece. The post is provided with a first track groove and a second track groove. The slider is arranged on the post. The first or second pulley is rotatably mounted on the slider and arranged in a row along a longitudinal direction of the slider, and extends into the first or second track groove, so that the first or second pulley pulley abuts against an inner wall of the first or second track groove. The fixing piece is mounted on the slider and includes a fixing part matchingly fixed with the post, when the fixing part is matchingly fixed with the post, the slider is fixed to the post, and when the fixing part is separated from the post, the slider is movable along a longitudinal direction of the postumbrella sliding assembly.

A straight-pole sun umbrella hand-cranking structure includes a standing pole and a shell fixed on the standing pole, wherein the shell comprises a first outer shell and a second outer shell. The shell is integrally fixed with one side of the standing pole, and a gear is arranged within the first and the second outer shells. A cranking shaft passes through the gear and is connected to an anti-slip mechanism, and a cranking handle is externally connected to the cranking shaft. The anti-slip mechanism includes a torsion spring, wherein the torsion spring is sleeved on the end portion of the cranking shaft. The torsion spring is arranged at the tail end of the cranking shaft such that the anti-slipping performance is improved by the elastic force of the spring. As the aforesaid structure is protected against abrasion, its functional life is significantly prolonged.
