Screw and screw driving apparatus

摘要

The system generally comprises a nail that engages an assembled screw driving apparatus. The apparatus is typically stored in a ready position and moved to the load position in order to affix the nail to the apparatus. In the ready position, a top section of the bit extends beyond the end of the cylinder. The nail can now be easily fitted with the top section of the screw bit. The nail is fitted with the screw bit, and depressed into the apparatus. The apparatus automatically enters a drill position, in which the nail is locked to the apparatus and drilling begins. The nail will be released from the apparatus at a certain distance from the substrate. The nail is further rotated to drill the nail to a predetermined depth in the substrate. Once screwing is complete, the apparatus is removed from the nail and the apparatus automatically returns to the ready position.
