The invention discloses a cat-head tower and a loop structure thereof. A main traverse line cross arm can extend and contract in the length direction of the main traverse line cross arm. One end of afirst crank arm is connected with one end of the main traverse line cross arm; one end of a second crank arm is connected with the other end of the main traverse line cross arm; the other end of the first crank arm can be rotationally connected with the other end of the second crank arm so that the main traverse line cross arm can be translated up and down; or both the first crank arm and the second crank arm can extend and retract in the respective length directions to make the main traverse line cross arm to translate up and down. The cat-head tower also includes a locking mechanism for locking or releasing the rotation movement and telescopic movement. The main traverse line cross arm, the first crank arm and the second crank arm cooperate to form a tower window; a first insulator string and a second insulator
