An improved structure of a screw mounting device comprising a machine body, a machine tubing, a controlling module and a retractable adjusting device located at one lateral side of the machine body, the end face of the front end of the machine body being a sloping side to allow a sliding wheel of the controlling module to urge against the sliding, the controlling module comprising a guiding rod, the sliding wheel and a cavity body and the controlling module located at the side of a screw insertion slot module, characterized in that the lateral side of the sliding rod is extended to provide a <CUSTOM-CHARACTER FILE="US06412370-20020702-P00001.TIF" ALT="custom character" HE="20" WI="20" ID="CUSTOM-CHARACTER-00001"/>shaped holding block, and the holding block is appropriately mounted at a recess located at the bottom section of the screw-pushing plate, the sliding wheel is pivotally mounted at the top section of the guiding rod, and the bottom section of the guiding rod is provided with a spring within the cavity body, thereby when the sliding wheel urgingly slides together with the sloping side, the guiding block is simultaneously moves upwards or downwards according to the sloping side, so that the holding block drives the sliding block to move upwards or downwards with the sliding slot, and therefore the screw-pushing plate can urge against the bottom section of the screw, and the screw is elevated until the screw rod is inserted for mounting.
