New description: [New technical field] The present invention relates to a design of a locking component, in particular to a screw. [Prior Art] See the picture! 'The conventional screw i includes a rod U, which is disposed on the rod _12... a drill lock portion provided at the end of the rod body, and a threaded ridge provided on the rod body u by a plurality of spiral rings; Wherein the drill lock portion has a tapered shape, so the screw: when the lock member 2 is locked, the drill lock portion 13 is drilled and locked, and the screw thread lock is guided into the lock member. 2' to achieve the lock positioning effect. However, after the actual use, it is found that the conventional screw 1 can lock the lock member 13 for the locking member 2 during the locking of the lock member; however, the locking process t, Due to the limited taper shape of the drill lock η, the screw 1 can only be pushed into the lock member 2 by the tapered design, so that the chips generated during the drill lock are not only impossible. It is effectively cut off, and is only pushed by the drill lock portion 13 to be squeezed, so that the cut can not be smoothly discharged, resulting in the screw! When the screw is inserted into the lock member 2, it is easily hindered by the cut, and the locking resistance of the screw 1 is increased, and the screw is at the same time! The I method in the process of locking; the combination of the lock and the lock member 2 affects the material of the actual application. Furthermore, the screw is locked at the position indicated by the imaginary line of FIG. 2: the position of the screw head 12 of the screw is erected when the lock σ is locked, which causes the screw head 12 to be smashed upwards and Α , It is easy to produce water and rust, so the current 3 M422611 to avoid this situation, the screw 丨 is locked into the lock member 2 towel in a tilting manner, because the screw, silk 丨 μ cut is not smooth The discharge condition causes the screw head 12 to be attached to the outside of the lock member 2, which affects the subsequent jointing of the lock member 2 and is in a state of mutual engagement, so the structure of the screw 1 is practically designed. There is room for improvement to solve the aforementioned lack of use. [New content] Therefore, the purpose of the present invention is to provide a screw having a function of reinforcing chip removal to reduce the generation of the locking torque and thereby increase the locking speed, and the screw can be buried in the lock member after the lock Inside. Yu Yu, the new type of screw mainly comprises a rod body, a screw head, a drill lock portion and a plurality of threaded teeth provided on the rod body; wherein the drill lock portion is formed with two inclined cutting faces, and the a cutting edge is formed at the junction of the two cutting faces, and a plurality of threads disposed on the rod body extend to the cutting edge, and one end edge of the cutting edge is connected; that is, the cutting edge is drilled and cut The chip generated by the drilling and cutting process is scraped off, and the cutting surface is guided to guide the chip to smoothly enter the chip passage between the teeth to quickly discharge outward, so as to avoid a large amount of chip accumulation, and effectively reduce the locking torque and the lifting lock. At the same time, the screw can be easily buried in the lock member after the screw is locked, which is beneficial to the subsequent parallel construction of the lock components. The foregoing and other technical contents, features, and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the drawings. In the following description, like elements are denoted by the same reference numerals. Referring to FIG. 3, a preferred example of the screw 3 includes a cup body 31, a screw head 32 that is at the end of the rod body 31, and a drill portion that is disposed at the other end of the rod body 31. 33, and a plurality of helical loops 34 are disposed on the rod body 31; wherein the threaded teeth 34 are formed with a chip passage 341, which is further referred to FIG. 4, in particular: the drill lock portion 33 A cutting surface 331 having two inclinations is formed, and a cutting edge 332 is formed at the intersection of the two cutting surfaces 331, and the cutting blade 332 has a cutting and cutting component 4 and a chip scraping effect generated by the drilling process, and at the same time The thread 34 disposed on the rod body 31 extends to the cutting blade 332 and is in contact with any end edge 333 of the cutting blade. Therefore, the chip passage 341 can be brought into communication with each other by the screw thread 34. Referring to FIG. 3 and FIG. 5, when the lock is engaged, the drill 32 is used to apply the rotary lock 33 to the rotational torque, so that the cutting edge 332 is rotated by the screw 32 into a lock member 4 (eg, In the composite plate shown in FIG. 3, at this time, the screw 34 is extended to the design that the one end edge 333 of the cutting edge 332 is connected so that the cutting edge 332 is in progressive contact with the lock member 4. The cutters 34 are driven into the lock member 4 to form a drilling effect during the cutting process, and at the same time, the cutting faces 331 of the cutting edges 332 are matched during the locking process. Auxiliary, so that the cutting chips generated by the cutting edge 332 are cut by the inclined design, and the two cutting faces are extended to the threads 34, so that the cutting faces of the two cutting faces 331 are locked when locked. 'Being able to connect to the chip discharge 胄341, the swarf can be quickly and smoothly discharged through the chip passage 341, so that a large amount of chips can be prevented from hoarding and squeezing, so that the screw 3 After gradually locking and burying in the lock member 4, the screw 3 can be stably fixed. In this case, the screw 3 can be embedded in the lock in the upright manner or in the tilting lock mode during the locking process, so that the screw 3 can be buried in the lock after the lock is engaged. In the component 4, it is more advantageous to carry out the subsequent parallel construction of the lock components 4. In summary, the new type of screw has two cutting faces formed on the drill locking portion, and one cutting blade is formed at the intersection of the two cutting faces, so that the locking and the cutting face cooperate with the cutting blade and the two cutting faces. Auxiliary, so that the chips generated during the locking process can be quickly removed through the cutting surfaces of the cutting surfaces, so that the chips are prevented from hoarding, so as to effectively reduce the locking torque and improve the locking smoothness. The effect is the same, and at the same time, the screw can be buried in the lock component, and is more suitable for the parallel construction of the lock compound, so it can achieve the purpose of the novel. However, the above description is only for explaining the preferred embodiment of the present invention, and it is not possible to limit the scope of the implementation of the present invention, that is, the simple equivalent of the novel application-Lu patent garden and the new manual content. Changes and modifications shall remain within the scope of this new patent.
