Description
Technical field
The utility model relates to daily life tools, especially for timber and the employed drive screw technical field of associated materials.
Background technique
At present, timber commonly used has straight nail and drive screw with nail, but they have distinct disadvantage.Straight nail is crooked easily and can not use screwdriver, and is fastening not as drive screw to timber, is difficult for pulling out; Drive screw tip in use is crooked easily, and the screwdriver application of force is not enough, so drive screw is difficult for the upright timber that gets into, life people usually punching in advance re-use screwdriver fastening screw peg.
Summary of the invention
For the defective and the deficiency that overcome existing technology, the utility model provides a kind of drive screw.
The technological scheme of the utility model is: the design is made up of ailhead, nail bar one, nail bar two and nail point, and ailhead is made as " cross " shape; Nail bar one is a screw-like, and nail bar two is cylindric.Being about to straight nail front end and drive screw rear end combines.Nail bar two adds that the length of nail point is 1/3 of said screw thread ailing length, and it is 2/3 of said screw thread ailing length that ailhead adds the length of following closely bar one; The design's material is irony or cemented carbide.
The beneficial effect of the utility model is: both kept the tightness of drive screw, drive screw is uprightly hammered into easily, it is simple in structure, and is easy to use, is easy to promote.
