New description: · ' 【New technology field】 ^Creation department - Caiguan self-tapping screws are good, which is based on the self-tapping screws when the knife is at least a special financial engineer and used from f Silk for reading solids, can increase self-tapping _ (four) speed 〇 [previous technology]. According to the self-tapping screw structure, as shown in Figure 1, at least the system includes - screw part (11) and a drill portion (12) formed at a tip end of the screw portion (11), the drill portion (12) having a second blade portion (121) centered on the axis and symmetrical, and the second blade portion 21) The screw portion (ι) extends the chip flute (122). This kind of self-tapping screws are often used to fix the metal wave board when wearing the attacking wave board or steel frame. At the beginning of the attack, the self-tapping screws will have at least two knives (121) in contact with the object being drilled and attacked. By using the cutting and arranging action + of the one blade portion (121) and the chip flute (122), a drilling hole which can facilitate the screwing of the screw portion (11) is formed; however, if the blade portion (121) is at the beginning Damage, collapse, and cracking in the process of attacking or cutting will inevitably reduce the self-tapping screw cutting effect, and even form invalid cutting, which will affect the overall operation efficiency. Therefore, it is necessary for the phase (4) to explore and provide improvements to the defect. Means. [New content] In view of the above, in order to improve the above-mentioned self-tapping screws, the applicant has to solve the problem of providing a new type of self-tapping screws that maintain the cutting edge function and effectively accelerate the cutting efficiency. In order to achieve the above objectives, the technical means proposed by this creation is to raise 3 M383053
( 242)，令該鑽頭部（22)儼然具有複數個刃部及排屑 槽。 藉由上述結構加以實施後，本創作之自攻螺絲結構 改良中，係可由第一刃部（221)及第二刃部（223)產(242), the drill portion (22) has a plurality of blade portions and chip evacuation grooves. After the above structure is implemented, the self-tapping screw structure of the present invention can be modified by the first blade portion (221) and the second blade portion (223).
生始攻切削作用，當鑽孔擴大後，該二刃部（221、223) 後方的至少一切割槽（24)也會參與切削作用，由於提 高切削量的緣故，因此可有效增加自攻螺絲的切削及攻 入效率’使工程作業之時間縮短；此外，當第一刃部 (221)及第二刃部（223)之切削刀刃有損壞的可能時， 後方至少一個切割槽（24)也會延續切削作用，讓自攻 螺絲順利完成攻入鎖固的動作。 綜上所述，本創作之自攻螺絲結構改良，確實已達 3設ί目士的’實已符合產業之需求，爰依法提出專利 、，:’本創作雖已以前述較佳之實施 狹盆 j用以限料創作，任何熟悉此技藝者，在不脫離: 創作之精神和範圍内，當可能加以刊餉^At the beginning of the cutting action, when the drilling hole is enlarged, at least one cutting groove (24) behind the two-blade portion (221, 223) also participates in the cutting action, and the self-tapping screw can be effectively increased due to the increase of the cutting amount. The cutting and tapping efficiency' shortens the time for engineering work; in addition, when the cutting edges of the first blade portion (221) and the second blade portion (223) are damaged, at least one cutting groove (24) at the rear is also The cutting action will continue, allowing the self-tapping screws to successfully complete the locking action. In summary, the self-tapping screw structure of this creation has been improved, and it has indeed reached the requirements of the industry. It has been patented according to law, and: 'This creation has been implemented with the above-mentioned better implementation. j is used to limit the creation of materials.
