V. New description: [New technical field] j · This creation is about a type of self-drilling screw, especially a self-drilling screw with a stable fixed position and fast cutting and locking. [Prior Art] Referring to FIG. 1 and FIG. 2, the conventional drill screw includes a screw head 11', a rod body 12', a plurality of threads 13 formed in the rod body and extending in the axial direction, and a drill tail η is formed; wherein the drill tail portion 14 extends forwardly from the center line to a drill point 141, and two symmetrical chord cut surfaces 142 are opened on the drill point 141, and the chord cut surface 142, a row of groove 143' and a side edge 144' are formed on the row, and the end edge 145 is formed at the drill line between the drill tip 14 Γ and the side edges 144. When the lock is engaged, the drill tail screw 1 is first fixed on the surface of the object 2 by the drill tip 141, and then the end edge 145' and the side cutter 44 are used to drill the object 2, and the object is cut. The generated chips are led out by the chip flutes 143', and then the plurality of threads 13' are tapped into the object 2 for locking, and the drill screws 1 are focused on the stable position and fast in actual use. Two major effects of cutting. However, 'the actual use found that the self-drilling screw 1 still has the following two major drawbacks: h As shown in Fig. 1, the drill tail screws 1, the drill tail portion 14, due to the continuation of the central 141' and the two sides of the blade 144, The end edge formed by the drill line 45' is M424409

As shown in FIG. 2, the tail portion 14 of the drill tail screw 1 is obtusely formed by the end knife 145 formed at the drill line between the drill point 141' and the side edges 144'. The side edge 144' and the drill tip 141 have a short distance A. When the object 2 is locked, the two sides of the blade 144 can be immediately inserted, so that the cutting speed can be performed, so that the drill tip 141, The angle is large, not enough to protrude, and the positioning function is insufficient. When the screws are used to break the object 2, the valley is prone to displacement, which increases the difficulty in construction. Therefore, the creator has the above two drill-tail screws, but there is still a lack of positioning, the attack speed is slow, or the attack speed is fast, the lack of positioning is lacking, so = years of professional experience in this field of technology, for the sake of The concept of product excellence, especially for the shortcomings of the above-mentioned drill-end screws. Innovation, in this way, finally succeeded in the development of a design that can indeed be combined with === speed cutting, which will achieve the value of the industry. [New content] This creation is related to a kind of self-drilling screws, which are mainly composed of a screw head, a rod body, a plurality of threads formed in the dragon and extending axially, and a tail portion of the drill. (4) The tail extends forward from the centerline—the drill tip, and is opened at two sides: there are two symmetrical “chord cuts and the chord cuts form one: two: rear extension; and the aforementioned drill tip and the two sides of the knife An end edge is formed at the drill line, and the read end cutter is concave.

[Embodiment] This creation department provides ~ kinds of self-drilling screws. In order to make your review understand the creation of this work, * members can enter the structure and characteristics, and attach a detailed description to the following, first, read " Referring to Fig. 1 _ n, H, the boring screw 4 of the present invention is composed of a ridge η at a month m 2 , a plurality of screw edges formed in the shaft and extending in the axial direction, and a middle tail portion 14; The drill tail portion 14 is forwardly centered on the center green, and has two symmetrical string cutting/continuation tips 141, and the material 141 is flanked on the tail portion 2 of the drill, and the thickness of the (four) plane 142 is thickness. 1/4 to 1/2 of the 'and a chip flute 143 and a side edge 144 are formed on the chord section I" M424409 and extend backward, and the drill line between the aforementioned drill point 141 and the two side edges 144 An end edge 145 is formed at the same time, and the end knife 145 is recessed. Please refer to FIG. 4 and FIG. 5' for a front view and a side view of the drill tail portion 14 , wherein the chord cut surface 142 of the drill tail portion 14 is cut by the drill point 141 to the left and right sides and is symmetrical with each other. a side edge 144 is formed at a side end away from the center line, and a concave end edge 145 is provided at the front end, and the end edge 145 is located farther from the end point 146 of the center line than the drill point 14ι; thereby making the iron The tip 141 is more convex and positions the end 146 of the front edge ία closer to the horizontal position of the drill tip 141. When the drill screw of the present invention is used, please refer to FIG. 6, FIG. 7 and FIG. 8. The drilling function of the workpiece 2 is started by the drill tip 141 of the drill tail portion 14; when the rod body 12 is 12 When rotating, the cutting hole can be drilled by the end edge 145 of the drill tail portion 14. At this time, since the 145 series is concave, the 'slot 141 can be positioned to be misaligned*, and the slippage-moving phenomenon is generated. Since the position of the end 146 of the front end of the two side edges 144 is closer to the horizontal position of the drill tip 141, the two sides of the blade 144 can be immediately inserted into the figure 2 for strong and powerful drilling, and the accurate positioning can be easily achieved. The purpose of rapid boring. Moreover, as shown in FIG. 9, in order to achieve the dual function of optimal positioning and the fastest cutting speed, the drill tip 141 of the drill tail portion 14 and the end point 146 of the two side edges 144 form a lost angle of 0, which is optimal. The angle is 115 degrees to 145 degrees. 6 M424409 According to this, it can be clearly seen from the above that the drill-tail screws designed by this creation are mainly extended to the center of the drill tail 14 - the iron tip 141' and open on both sides of the drill tip 141 The solid thickness is two symmetrical and front-end recessed chord planes 142 between 1/4]/2 of the solid thickness of the iron tail 14 to form a concave end edge 145, which is designed to make the drill tip i4i more convex. And the knife 144 on both sides can penetrate the object 2 at the shortest distance; therefore, it can be accurately positioned, and the hole can be quickly drilled for cutting and tapping, so that the operation is stable and fast, and the positioning is stable and fast locking. Therefore, the design is designed to be screwed into the work by the concave end edge 145, which has the practical function of accurate positioning and rapid cutting, so as to improve the working efficiency of the self-drilling screw and can be used in industrial use. It fully demonstrates the practical technology and utilization value of the staggered screw in the industry, and further enhances its competitiveness in the industry market. The above detailed description is intended to be illustrative of a possible embodiment of the present invention, and is not intended to limit the scope of the present invention. It should be included in the scope of this creation patent. In summary, this creation is not only innovative in terms of space type, but also enhances the above-mentioned functions compared with the prior art. On the whole, it has excellent industrial use value and practicality, and it is an excellent one.
