The structure of a screw nailer includes a body with a functional space inside; a rotary driver, placed in the functioning space rotated from a point of support and having a gear wheel that moves the nail belt; a one-way driving component moving the rotary driver in a single direction; an indexing fixer creating elastic positioning when the rotary driver turns in a direction in a preset angle, so that the rotary driver achieves the indexing positioning. A blockage fixer, and by position of the blockage fixer to nail the screw by rotational inertia when the rotary driver of the screw nailer is rotating in direction with preset angle to keep the nail belt from turning the angles, so that the screws may be nailed accurately and securely to the designated location, and largely increase the accuracy, quality and effects of the screw nailer operation.
