The utility model provides a guide rod type block for helicopter paying-off. The guide rod type block comprises a block frame, a guide rod arranged in an inclined manner and fixed with the block frame, a rotating disc arranged in the upper part of the block frame and sleeving a rotating disc supporting shaft, a pulley assembly arranged in the lower part of the pulley block, and a rope falling channel and a triggering mechanism which are arranged between the rotating disc and the pulley assembly. The rotating disc is located below the guide rod and has a rope inlet notch. The triggering mechanism comprises a push rod, a stopper, and a rotating shaft. The push rod and the stopper are intersected and fixed, and are both connected with a block frame shaft. The push rod is arranged inside the rope inlet notch, and the stopper limits the rotation of the rotating disc. A steel guide rope applies a force onto the push rod to drive the stopper to rotate, and thus the stopper and the rotating disc are detached. The rotating disc drives the steel guide rope to fall, and the steel guide rope falls into the pulley assembly through the rope falling channel. According to the utility model, the block automatically completes the direct paying-off of the steel guide rope, increases the helicopter paying-off speed, allows the steel guide rope to be taken out manually through a backward rotating disc, and increases the speed of a wind-draw dividing procedure of the steel guide rope.
