The invention discloses a power cable construction manual wire rod hole-digging machine. The power cable construction manual wire rod hole-digging machine comprises an outer cylinder of a barrel shape, an end head is connected to the outer cylinder, a first cylinder cavity is formed in the outer cylinder, and an inner cylinder which rotates in the first cylinder cavity is arranged in the first cylinder cavity. A second cylinder cavity is formed in the inner cylinder, a second groove of a triangular shape is formed in the end head, the second groove and the first cylinder cavity correspondinglycommunicate with the second cylinder cavity, the second groove is internally provided with a driver disc connected with the outer cylinder correspondingly, the second cylinder cavity is internally provided with a driving mechanism which drives the driver disk to rotate, so that the driving mechanism can be used for driving the driver disk to rotate in the up-and-down sliding process of a slidingshaft, and the outer cylinder is driven to rotate. The outer cylinder and the end head are separately provided with spiral discs of a spiral shape, so that the spiral discs can be used for realizing the auger drilling on the ground, and the damage to crops caused by large excavators is further avoided.
