The invention discloses an adjustable tower crane attachment wall connecting rod and a manufacturing method thereof. The adjustable tower crane attachment wall connecting rod comprises a bottom plate, a single-lug plate is arranged in the middle of the bottom plate, a second double-lug plate is arranged at the bottom of a third tubular structure and connected with the single-lug plate, a dual-directional adjusting screw rod is arranged between the third tubular structure and a second tubular structure and fixedly welded to the third tubular structure and the second tubular structure, the second tubular structure is inserted into a first tubular structure, first through holes are evenly formed in the first tubular structure, and second through holes are formed in the second tubular structure. The length of the tower crane attachment wall connecting rod can be adjusted in two length adjustment modes, one adjustment mode is intermittent adjustment achieved through cooperation of the first through holes, the second through holes and cylindrical pins, the other adjustment mode is linear adjustment through the dual-directional adjusting screw rod, when the length adjusting interval of the dual-directional adjusting screw rod is larger than the distance of the through holes in the single group, the length of the tower crane attachment wall connecting rod can change in any range, and accuracy and operability are high.
