New description: [New technical field] [0001] This work is about a kind of screw, especially a screw with a triangular shaft and a serrated cutting edge at the lower end of the screw to improve the construction efficiency and stability effect. Structural improvement. [Prior Art] [0002] The screw has the advantage of fast locking and fixing the workpiece, so it has been widely used in workpiece joining, and the corresponding design is adopted according to the material or size requirements of the workpiece. [0003] In the case of a conventional woodworking screw, the utility model comprises a screw head and a round rod body with a bottom end and a pointed vertebra, and the rod body ring is provided with a screw segment, and the taper portion is used for construction. And the screw segment screwes the screw into the workpiece to form a lock. [0004] However, the disadvantage is that when the screw is screwed into the workpiece, except that the taper portion is subjected to the resistance of the workpiece material during cutting, since the screw rod body and the screw segment are rounded, the screw is screwed in. When the workpiece is in contact with the workpiece, it is in line or surface contact, which also causes a large friction force when the screw is pushed in. The user has to spend more effort and time to lock the workpiece with the screw; in addition, the conventional screw is not The chip removal structure is arranged, and the scraps generated during the screwing tend to remain in the workpiece to form friction and push with the workpiece, which may cause cracks in the workpiece due to extrusion, which is necessary for improvement. [New Content] [0005] In view of the shortcomings of the above-mentioned conventional screws, the creator has provided a screw structure that can reduce the cutting resistance and increase the screwing efficiency by screwing design and manufacturing experience for many years.
