New description: [New technical field] t A kind of screw head improvement. [Prior Art] Generally, the combination of 4 pieces is mostly fixed by screwing, and the design of the screw must be different according to the difference of different objects (4) and the different characteristics of the unique material. design. However, in the design of the screw head, often due to the material problem of the object (the difference between the hardness of the material and the material fiber _ degree of the road), after the screw is turned on, the burr residue of the wire hole is generated and exposed to the lock. Shortly after the lion's head, the secret practical benefits and the lack of industrial use. To this end, the industry has designed and created such as the known announcement No. M34669 螺丝 "screw structure", announcement No. 8778 "anti-cracking screw", announcement of the waking side number "improvement of anti-cracking screws", announcement No. 311654 "Improvement of Locking Screws", Announcement No. 336705 "Improvement of Flathead Screws with Knife Shaw Knife", Announcement No. "Nozzle Screws" and Announcement No. m827 No. "Anti-cracking and Anti-Fringing Screws" Previous authoring techniques. There is no shortage of ribs and spurs on the snails. The ribs are protruding to prevent the occurrence of debris on the burrs of the job. For example: a σ M34669G "_Structure" is a set of reinforcing ribs extending from the upper end to the lower end of the lion's head. The so-called rib is a vertical straight strip design. The screw looks at the strength of the cap that cares about the lower drive. No. M388578 p-split screw and bulletin No. 3 preface "Improvement of anti-cracking screw" is provided on the upper and lower edges of the screw _.

本案「螺絲改良」主要創作目的在於··有效防止螺絲孔毛邊 殘屑的產生，使螺絲鎖合後的物件表面平整乾淨。 其特徵在於··位於螺絲桿體頂端的螺絲頭外徑為上大下小，在螺 絲頭本體的頂端與底端間的表面上設有至少一個(含)以上且旋轉至少 360度(含)以上的螺旋凸肋，其螺旋方向為反向螺旋，該螺旋凸肋的外 肋壁具有一設定角度的傾角，内肋壁亦具有一設定角度的傾角，使外 肋壁與内肋壁交會處構成螺旋凸肋的刀刃。 藉由本案創作能在螺絲頭螺入物件時，利用創作所設具有刀乃的 4 M436104 螺旋凸肋產生截斷制並反向壓喊屑人物件⑽_，確實達到螺 絲鎖合後的物件表面平整乾淨的效果。 【實施方式】The main purpose of the "screw improvement" in this case is to effectively prevent the generation of debris from the burrs of the screw holes, so that the surface of the objects after the screw locks is smooth. The utility model is characterized in that: the outer diameter of the screw head at the top end of the screw rod body is upper and lower, and at least one (including) or more and at least 360 degrees (including) is provided on the surface between the top end and the bottom end of the screw head body. In the above spiral rib, the spiral direction is a reverse spiral, the outer rib wall of the spiral rib has a set angle inclination, and the inner rib wall also has a set angle inclination so that the outer rib wall meets the inner rib wall The blade forming the spiral rib. In this case, when the screw head is screwed into the object, the 4 M436104 spiral rib with the knife is used to create the cut-off system and the reverse-squeezing character piece (10)_, which is sure that the surface of the screw-locked object is flat and clean.
