The invention discloses a finger stall type rod tower aerial climbing anti-falling safety latch. The latch comprises a left lock head device and an U-shaped hanging ring; the left lock head device includes a left half buckle and a right half buckle; the two half buckles both include locking ends and transfer ends; the transfer ends of the two half buckles are rotationally connected through a pin shaft; the locking ends of the two half buckles are buckled; after the two half buckles are locked, a closed ring for holding a rod tower foot ladder is formed in the center; finger stall holes for penetrating through fingers are respectively formed in the two half buckles; a closed rod is arranged in an opening of the U-shaped hanging ring; and the left lock head device is connected with the U-shaped hanging ring. The latch has the following advantages: the effective fixation can be performed, and meanwhile, the connected U-shaped hanging ring can be convenient for workers to hang a safety rope, so that the safety of the workers climbing a rod tower is greatly improved; the operation of the device has no need to consume excessive physical strength, so that the workers keep the physical strength to perform the climbing operation; and meanwhile, compared with a traditional rail anti-falling device, the latch largely reduces the cost, and is convenient to popularize and apply.
