The present invention relates to a power block for towing a stow net. According to the present invention, the power block for towing a stow net, which is a power block installed at an end of a crane installed on a fishing boat to tow the stow net, comprises: an upper frame; a connecting ring installed on an upper side of the upper frame to be connected to the crane; left and right frames installed on both sides of the upper frame; a rotation shaft installed between the left and right frames; a driving unit installed on one side of the left and right frames to rotate the rotation axis; a fixed block fixedly installed on the rotation axis to have an inward inclined surface; a moving block having an inclined surface opposite to the inward inclined surface of the fixed block and moving horizontally along a spline formed on the rotating shaft; and a horizontal moving means installed on the other side of the left and right frames to horizontally move the moving block along the rotation axis. The power block for towing the stow net according to the present invention moves the moving block horizontally along the rotation axis such that a traction force of the power block can be kept constant even if the width of the stow net is reduced during a traction process of the stow net.
