A spiral ring is disposed on the rod body: a thread 13 and a rod on the rod body 12 opposite to + the taper surface 14 of the screw head a; wherein, any of the two threaded teeth 13 is convexly provided with a protrusion 131 and is located adjacent to the S-shaped protrusion 131 | η... Stretching-ribs--the ends of the dog-outlet 131 are connected to each other; therefore, when the fiber locks the compound 2, the protrusion i3i and the rib can be pushed up by 32 = medium to achieve the reaming effect, and the subsequent The thread 13 is smooth: into the lock compound 2. τ "Smooth lock ^ found after the actual use, the screw is easy to have the following missing, as detailed below:, 1 _ conventional screw 1 locking process, # m '* by the rib 132 and protruding: two Reaming is achieved, and then the post-integration speed is increased; but in the initial stage of locking, the conical surface is pressed into the crucible, and the lead drilling and pushing are still performed only by the screw 13 of the taper=4. In the process, easy to make;: tooth 13 can not completely cut the wood fiber, resulting in the wood fiber is very easy to wrap around the rod into the m A, but increase the screw i lock two = make: shaving Relatively slower, and the locking process is also more costly, and it is still necessary to change the cover. 2. Continued the above, supplementing (4) not reading the city and other nuclear dimensions, causing 4 14 pushes, and subsequent cuts When the hole is reamed, the locking force of the wood fiber is greatly reduced. 5 10 15 20 M350622 The ribs 132 and the protruding piece 131 which allow some of the wood fibers to enter the tapered surface can exclude the wood. The effect of filament winding, the entanglement, the towel makes the Langs 1 lock [new content] It has effective cutting access, fast /,: The anti-cracking screw 'pu η Μ rn 、, the material generated by the locking process and the effect of increasing the locking force. So the 'the new anti-cracking screw contains the rod on the head, and _ 蜾浐 Lu Qi from. In the snail squat 疋 § § on the shank of the shank, and - is set on the shank and the free end of the phase cone surface is formed with - drill tip = cone surface 'where the tip door wins ° Hai The at least the cone surface is shaped like a slanted rib, and the ribs are arranged radially outward from the drill tip and are disposed obliquely to the center of the shaft, and:: formed between the ribs- Cutting surface, so in the process of locking, by the same: 'In turn, it can effectively cut the cut, enter the fast, prevent the cracking of the mouth process and increase the locking force. [Embodiment] In the detailed description of the above-mentioned and other technical contents, features and functions, and the preferred embodiment of the reference circle, the following will be understood. / Figure 2, Figure 3 is a preferred embodiment of the present invention. For example, the screw 3 includes a screw head 31, a % of the rod body disposed above the screw head, a spiral a thread 33 disposed on the rod body 32, and a tapered surface 34 disposed on the body 32 of the rod 5 M350622 5 10 15 20 and opposite to the screw head 31; wherein the cone surface is free A drill tip 34 is formed at the end, and at least three slit ribs 342 are formed on the tapered surface 34. In the embodiment, four aliquots are taken as an example for illustration, and the ribs are formed by the drill tip. 341 is disposed outwardly from the center, and is disposed obliquely to the center of the rod 32. The other two of the cutting ribs 342 are formed with a cutting surface M3, that is, the cutting rib 342 is connected to the drill at the end thereof. The tip 341 is connected to the junction of the rod 32 and the tapered surface 34. Referring to FIG. 4, when the anti-cracking screw 3 of the embodiment is locked to the lock compound 4 having wood fibers, the screw on the tapered surface 34 continues to enter the compound 4 and is then set at the tip. The plurality of ribs on the conical surface is the same as that formed between the two ribs 342. The cutting surface 343 sequentially cuts the wood fibers of the lock compound 4, so that the entanglement 33 and (four) 32 The wood fiber can be chopped and smashed, ::: reduce the entanglement of the wood fiber at the beginning of the drill lock, and increase the locking speed. At the same time, the rib 342 will also enlarge the aperture at the initial lock, ^: The chips generated afterwards can also be discharged through the expanded aperture, which can effectively avoid the outward extrusion of the chips generated during the cutting, that is, the effect of preventing cracking in the locking process. Furthermore, when the anti-cracking screw 3 pulls the runner & continuously locks into the lock compound 4 and gradually cuts off the rib 342 and opens the lock compound 4, the anti-four wire 3 In addition to the locking speed, the elastic restoring force of the lock compound 4 allows the thread 33 of the lock compound 4 to be wrapped around the rod body 32 6 5 10 15 M350622 when it continues to enter the lock contract. The anti-cracking screw 3 can tightly and greatly increase the fastening force. As shown in the above-mentioned lock compound 4, the above-mentioned anti-cracking screw is arranged on the tapered surface to the center to radiate the special rib and to use the drill tip for locking. Between the two cutting ribs, a cutting surface is formed, which is effective at the beginning of the gentleman's (four) and the like (four) auxiliary (four), in order to achieve the effect of having iirr, fast row 4, preventing cracking during the locking process and improving the fastening force. It can achieve the purpose of this new type. Already, the apricots mentioned above are only for explaining the preferred embodiment of the present invention, and the field cannot limit the new shape to the beginning. > 々々阁型申l...
