Description of the invention: [Technical field to which the invention belongs] ^ The invention is a fastening or fixing member belonging to an engineering element; a self-tapping screw that is available and tapping for wood engineering, construction, trucks or cargo hubs. Automatic chip removal [Prior technology] Self-tapping screw is a type that does not need to be directly rotated by a person before the tapping of the tapping, and the material forms the hole, and the door can be scraped with the cutting part at the front end. The holes are provided for the screwing of the rear section directly. In addition, it is set to two: r: r: scraping material in the cutting part. ^ Tail screw "new type =; Report No. 5 23057" Drill 79 Second Reference ") and the structure of the tail lock screw No. 55 b Improve the conventional self-tapping screw shown in Figure 2 of the reference case-Self-tapping screw Butterfly II; Figure: = For Known 'Whether it is known to cut the second two! There is a threaded part, and the cutting part is provided with -cut When the thin wing part of the screw 2 is rotated, when the self-tapping screw is on the wood board == the groove is scraped to remove materials and chips, and Qing You will ride the hole to form a hole on the inspection board, and the wing part wants to enter Everyone ^ ± the threaded part of the segment is directly screwed 2: :: is miscellaneous "will break" so that after 1233470 However, from the reference product of the seventh picture and the creation of the fourteenth figure, it can be seen that when the wing is broken, its The root (that is, where the wing is connected to the cutting part) will form a residual material protruding from the peripheral surface of the cutting part. The residual material is formed because the root of the wing is directly connected to the peripheral edge of the cutting part. When broken, because the metal material has an extension, it cannot be cut straight from the joints, so that it forms a protruding cut. The residual material on the peripheral surface of the part, the formation of the residual material will still have the function of reaming when passing through the metal plate, so that the perforation hole diameter of the metal plate will increase, so when the threaded part is screwed into the metal plate, The combination of metal plates will significantly reduce its bonding strength. According to the drawings of the reference case, the position of the wing portion of the existing self-tapping screw is set at the end of the cutting portion adjacent to the thread portion. Although it can form a reaming hole on the wooden board, it still has chip deposits when it is applied. The lack of labor, the cause: When the cutting part scrapes the material, the material is discharged through the cutting groove. It must pass through the wings before it can be discharged into the ream with a larger space. However, because the wings are located in the cutting At the rear end of the groove, the chip removal speed is still too slow, so that chip formation and laborious drilling are formed. [Summary of the invention] <Technical problem to be solved> In view of the fact that the self-tapping screw is often difficult to apply force due to debris build-up, and the metal plate is too large to perforate due to the remaining material of the wing break, it can not be tightly combined. A self-tapping screw of the present invention is developed that meets the above conditions. <Technical means and effects> The present invention aims to provide a self-tapping screw, which is to provide a strong screw that can improve the self-tapping screw and the metal plate by 1233470. ^ ^ And the self-tapping base that can accelerate chip removal and save effort; for the above purpose, the main free cutting part of the present invention, μ / segment of the wing part is set to cut another 1: the end of the bevel to the cutting cut;- Recessed recession = The edge of the cutting part is connected with the wing part, where r is set, that is, the point where the two are connected is lower than the peripheral surface of the cutting part. The material scraped by the cutting groove in the "two ways" is one: Cheng = 1/2 of the cutting groove can enter the reaming reaming hole rotated by the wing, which not only has the effect of accelerating the system, but also can prevent the accumulation of the product. Labor-saving and fast when cuttings are applied. , === the part through the metal plate and the actual break 'is not higher than the cutting but there is still a possibility, so that when passing through the metal plate, and the threaded part can be translated a larger part; gold: to length: ask The strength of its combination. [Embodiment] To understand the structure and characteristics of the present invention in parallel, the following preferred embodiments are attached with detailed illustrations such as =, but the implementation described in this illustration is for illustrative purposes, and is not a claim. The only limiter. Please refer to the first figure. The self-tapping screw (work) provided by the present invention is almost the same as the existing products of Co., that is, it includes-head (1), and extends from the head (11).
