New description: [New technical field] A modified design of anti-cracking screw which was improved according to the prior art creation No. 98224168 (new patent No. M388578). [Prior Art] - It is known that 岐 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The final screw and the material do not crack. In order to achieve the above objectives, there are single-stage 双, double-stage threads, and the same screw lead angle or different screw lead angle changes. The creators of this case also developed relevant creative designs on the technology of the lions, such as: Announcement No. 539〇67, Announcement No. 56 No., Announcement No. 570115, Announcement No. 575099, Announcement No. M259859 , the public's notice No. M258201, Announcement No. 371, Announcement No. _372, Public Notice* M299237, Announcement No., Announcement No. 27 No. and Public Publication No. 200525091. The design of the screw is different depending on the material of the screw to be screwed and the material properties, such as screws for metal materials, screws for plastic materials, and screws for wood materials. In the screw design for the known wood material, when the material of the hard wood is screwed, the wood often breaks due to the forced insertion of the screw due to the material properties of the hard wood, so the industry has also designed the material for the wood. Anti-cracking screws, such as Bulletin No. M350622 "Fracture-Resistant Screws", Announcement No. 3 M413770 1318270 "Fractures and Flange-Resistant Screws". The creator of this case f was made to deal with the shortcomings of the known lions, and took the new patent No. M388578 of No. 98224168 "Fracture-resistant screws", and it was better to improve the research and development of the assets. This technique is also necessary to re-develop the ride. [New content] The creation of the "anti-cracking screw" in this case is based on the improvement of the previous technical creation No. 9822 (the new patent right (4), = the effective drilling of the original crop should have the drilling screw, _ lion modified _, the improved anti-cracking screw includes a screw head - a straight rod extending from the screw head and a pointed taper tail at the end of the straight rod body; It consists of: There are three sections of thread on the straight body extending from the screw head. The first section of the thread is one meter and is close to the _ position. The second section of the thread is connected with a _ "" 'The second segment of the screw end distance #· screw tail seven 66 flute: ^ in the distance of the straight body is set by a predetermined reaming screw (4) ^ segment reaming screw, and the cone The double-drilled thread is provided on the tail of the screw; ^ & the third section of the thread is the single screw and the second thread is the spiral direction. = and the three-section thread on the screw straight body The overall innovative design of the double-drilled screw with the screw tail of the wooden body W at the end of the straight rod body is constructed as a hard Wood) a temple, can achieve anti-crack function and screw head and wooden objects 4 M413770 no residual wood chips are more ideal. [Embodiment] Please refer to the drawings (1) and (4) of the "Anti-cracking screw" of the present invention as shown in the attached drawings. The anti-cracking screw includes a screw head i and a screw head i. The extended straight body 10 and the pointed tapered tail 11 at the end of the straight body 1 are.
