A cantilever parasol comprising a post, a canopy and a cantilever, one end of the cantilever being rotatably connected with the post through a shell and another end of the cantilever being connected with the canopy, and the cantilever being rotated to drive the canopy to rotate so that an opening of the canopy is rotated by an angle to the horizontal direction; wherein the cantilever parasol further comprises a limiting member, one end of the limiting member being fixedly connected with the cantilever and another end of the limiting member extending into the shell, an inner wall of the shell being provided with a first limiting part and the limiting member being provided with a second limiting part, and the first limiting part being matched with the second limiting part to limit a rotation range of the cantilever in its circumferential direction; the first limiting part is a limiting groove circumferentially arranged along the inner wall of the shell, an end of the second limiting part inserted into the limiting groove, and a moving range of the second limiting part is limited between two ends of the limiting groove; the cantilever parasol further comprises a limiting display member, wherein the limiting display member is fixed to an end of the cantilever, one end of the limiting display member extends into the shell, and the other end thereof is exposed from the shell; the end of the limiting display member exposed from the shell is provided with a first limiting display block and the end of the shell is provided with two second limiting display blocks arranged at an interval; and the first limiting display block is located between the two second limiting display blocks, a movable range of the first limiting display block between the two second limiting display blocks is consistent with a movable range of the second limiting part in the shell, and when the cantilever is rotated, the second limiting part moves in the shell and the first limiting display block moves between the two second limiting display blocks at the same time, and a moving position of the second limiting part in the shell is indicated by a moving position of the first limiting display block. wherein the cantilever parasol further comprises a limiting member, one end of the limiting member being fixedly connected with the cantilever and another end of the limiting member extending into the shell, an inner wall of the shell being provided with a first limiting part and the limiting member being provided with a second limiting part, and the first limiting part being matched with the second limiting part to limit a rotation range of the cantilever in its circumferential direction; the first limiting part is a limiting groove circumferentially arranged along the inner wall of the shell, an end of the second limiting part inserted into the limiting groove, and a moving range of the second limiting part is limited between two ends of the limiting groove; the cantilever parasol further comprises a limiting display member, wherein the limiting display member is fixed to an end of the cantilever, one end of the limiting display member extends into the shell, and the other end thereof is exposed from the shell; the end of the limiting display member exposed from the shell is provided with a first limiting display block and the end of the shell is provided with two second limiting display blocks arranged at an interval; and the first limiting display block is located between the two second limiting display blocks, a movable range of the first limiting display block between the two second limiting display blocks is consistent with a movable range of the second limiting part in the shell, and when the cantilever is rotated, the second limiting part moves in the shell and the first limiting display block moves between the two second limiting display blocks at the same time, and a moving position of the second limiting part in the shell is indicated by a moving position of the first limiting display block.
