New description: [New technical field] The new type is related to the design of the drill-tail screw, especially for a self-drilling screw that can prevent the positioning offset and quickly lock the positioning. [Prior Art] Referring to FIG. 1 , a conventional tail screw 丨 includes a screw head u, a rod body 12 disposed on the screw head 11, a screw ring 13 provided on the rod body 12, and a screw a drill portion 14 formed at a free end of the rod body 12; wherein, the 3 cutting edge 14 has a drill collar - a conical surface 14 extending from the drill body 14G and at least - opening the conical surface 141, drilling a chip flute 143 on the body, and a tip 142 ′ is formed at the tip end of the conical surface 141 while the chip 胄 143 is tangent to the conical surface i4 i and is formed with a cutting edge 144 ′′ to “lock” Using the drill tip 142 to lie on the surface of the object (Fig. 2), and then drilling by the cutting edge 1, to guide the smashing screw i into the person, and then interlocking the screw to break into the lock Positioning. After the 'sinal system, it is found that the drill-end screw is still in perfect condition'. The details are as follows: "Drilling 142 is a single point, so only the tail U2 τι is used in the initial drilling. On the object, the single-drill tip 142 can not be firmly mounted on the surface of the object under the initial high-speed driving of the drill, which makes the drill tip easy to displacement on the surface of the object, resulting in the drilling process being affected by the ❻ (4) the whole 'invisible' The effect of the lock is slowed down. The degree of the twist is 4 M301955 5 2 · Since the drilled edge portion 1" and //recene 14 are drilled using only the two cutting edges H4 formed on the chip flute 143, Therefore, during the drilling and cutting process, the two cutting edges (4) are subjected to relatively large resistance, which easily leads to the cutting speed of the cutting edge 144 - even worse, the two cutting edges 144 are worn, which affects the progress of the locking cutting operation. needs to be improved.

Referring to FIG. 2, a first preferred embodiment of the present type of self-drilling screw 3 includes a screw head 31, a rod body 32 disposed on the screw head 31, and a spiral ring centered on the center line α of the rod body. a thread 33 on the peripheral surface 321 of the rod body 32, and a drill blade portion formed at a free end of the rod body 32; wherein the angled cutter #34 has a drill body 340, and one of the drill body 340 The outer extending conical surface 341 and at least one chip opening 343 formed on the conical surface 34丨 and the drill body 34〇 are simultaneously tangential to the conical surface 341 and formed with a cutting edge 344. In particular, a center of the center line of the shaft and located on the circular surface 341 is provided with a chord cut surface 345', and the string cut from 345 is a circular shape in the present embodiment, and the chord cut surface 345 The circle encloses a chamber (10), and the string cut surface 345 and the conical surface 34 are arranged to be chipped, and the groove is equally tangent to form a drill cutting edge 346 and a second drill point 347, respectively, and the drill tips 347 are in the same The horizontal position is open. In conjunction with the tea reading Figure 3, when the drilling screw 3 is engaged in the lock cooperation, the first use of the two drill tips 347 in the same too single you quit ^ ^ water thousand position design, so that the tail screw 3: in %, the bottom The surface of the object 4, when the screw head (not shown) (4) is driven by the torsional surface speed, the cutting screw 3 can be smoothly interlocked except that the self-drilling screw 3 does not produce a sliding bias. With the simultaneous action of the drill cutting edge 3, the drill tail screw 3 has two slits (ie, the cutting edge 344 and the cutting edge 346) - the auxiliary chip of the entry point (eight) and the entry point (ie, the two drill points 347) In the mode, first on the object 4 +7? (1) mountain, cut a notch (not shown in the figure), and then supplemented by the cutting edge 344, the fork is cut by the gap, expanded into holes, fast 6 5 10 15 .20 The effect of M301955, finally driving the self-drilling screw 3 to quickly lock and position. Referring to Figure 4, the first embodiment of the new type of self-drilling screw 3 is particularly in the case of the conical surface arc-shaped drill... , the cutting blade 344 can be chord cut; = two outer, and the conical surface 341 is arc-shaped design, which will help generate L;"4 strength, to reduce the tail screw 3 locking and tearing Referring to Figure 5, the third preferred embodiment of the novel self-drilling screw 3, should be = containing the screw head 3 rod 32, thread 33 And the components such as the drill knives and the like, the structure and the connection relationship of the two components are the same as the first description, and will not be described in detail; in particular, the chord cut surface 345 has a cone which is larger than the diameter of the two drill 347. The body 349, the cone 349 can be a five-corner triangular cone (as shown in FIG. 6) and the like, and in the embodiment of the present embodiment, the cone 349 is a five-corner cone as an example of the locking action. When the lock cooperation is carried out, the convex cone 349 is firstly used to position the surface of the object 4, and then the drill tail screw 3 has two slits (ie, the cutter 3 "disc, cutter 346"). In the auxiliary mode of the two drill tips 347, the drill tail screw 3 is allowed to perform the iron lock cooperation. Referring to FIG. 7 ′, a fifth preferred embodiment of the present type of self-drilling screw 3 further includes a threaded member 3, a threaded rod 33 and a member such as a drill portion, and the construction and connection of the aforementioned members. The relationship is the same as that described in the third embodiment, and will not be described in detail; in particular, the position of the drill point 347 is located on the extending line of the peripheral surface 321 of the rod body, and the conical surface of the drill portion is 341 7 M301955 5

Moreover, of course, in addition to the structural design shown in the foregoing embodiment, it can also form the structure shown in FIG. 8, that is, the shape of the cone 349 is sharper than that of the previous embodiment, and the rest achieves rapid cutting efficiency. Both are the same as described in the previous embodiment and will not be described in detail. In the above description, the novel and the novels do have the following advantages and effects: 1. Since the drill has two drill tips, in the initial stage of the drill, the top of the two drill tips is used. The surface of the object can make the drill-tail screw firmly fixed on the surface of the object. Therefore, when the screw head is applied with a high-speed torque for the rotation lock, the drill tip is not easy to test the phenomenon of the X-ray spear, so as to ensure smooth drilling on the object. cut. 2. Continuing the above, due to the formation of the two drill tips, the boring portion is combined to form a cutting knives, and there is still a cutting edge formed, so when locked, the two drilling knives have two The cutting mode of the incision two-in point, that is, the cutting knife drilling cutter simultaneously performs the drilling and cutting, so that the drilling and cutting operation can be made faster, and the locking effect of the drilling screw is greatly improved. Because the drill is arc-shaped when it is suitable, and the chord cut surface can be arc-shaped at the right time, when the cutter and the drill cutter drill the object, the chord cut by the cutter The effect, in addition to the better 'scraping...' and the cutting edge and the cutting edge can withstand the cutting process to produce a force of 8 5 10 15 M301955 'reduce the cutting part and the cutting edge cutting damage phenomenon to facilitate the drilling and cutting The work is more labor-saving and smooth. In summary, the present invention has the advantage of preventing the force of the screw by the addition of the end point, and simultaneously matching the drilling and locking speed of the screw with the two-stage drilling material of the drill and the cutting edge. Therefore, it can indeed achieve the purpose of this new type. The above-mentioned ones are only for explaining the preferred embodiments of the present invention, and the simple equivalent changes and modifications made by the present invention in accordance with the scope of the novel patent and the new manual are not limited thereto. All should remain within the scope of this new patent.
