Description of the invention: [Technical field of the invention] The present invention relates to a screw design, in particular to a composite screw 5 10 [Prior Art] Referring to the drawing, the screw i includes a screw head u, which is disposed in the a snail, a rod 12 on the rod 12, a locking portion 13 provided on the rod body 12, and a first ring, a first ring of the flute ring, which is disposed on the rod body 12, The second tooth segments 14, 16 are in an "an intersection" and are slanted, so when the lock is engaged, the first and second segments are cut by the lock portion 13 and the body is oriented against the object #2 (such as wood) The spin lock enters the person, and finally reaches the lock positioning function. However, after the actual use, it is easy to have the following defects, as detailed below: In the process of locking the component, the screw can be cut for the wood, but the thread generated by the screw after cutting the wood fiber is easy. Because the screw can not completely cut the wood fiber, the wood fiber is wound on the rod, which in turn causes the resistance of the lock to increase, which affects the locking speed. 2. Continued above, since the screw is not sharp enough, it cannot be completely cut. Therefore, when the chips are accumulated and entangled, the chips are easily squeezed to form an outwardly squeezed condition, which is liable to cause the wood to crack and become more serious. It will cause breakage when the screw is locked and needs to be improved. 3. When the screw is smoothly drilled into the wood, once the wood is affected by the external force vibration factor, the screw is likely to be outwardly rotated, so the locking force still needs to be improved. 4 1318667 SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a compounding screw which has a fast locking and four-closing function and a material-preventing effect, and is preferably better in anti-loosening and anti-backing effects. 5 ❿ 10 15 Thus, the composite coupling screw of the present invention comprises a rod body, wherein the screw head disposed at the end of the rod body is disposed at the other end of the rod body, and the spiral ring is disposed at the a first and a second segment on the shaft; wherein the second segment is extended from the drill portion toward the screw head such that the first and the first segments are staggered while the second tooth The outer diameter of the thread of the segment is lower than the diameter of the thread of the first segment, and the plurality of slots are formed on the thread of the second segment and the groove extends outward to form a second cutting edge; In the process of the combination, the auxiliary cutting of the second tooth segment is used to surely scrape the chips generated by the cut object, and the rod body is unwound, accelerates the locking speed, and the chips do not squeeze each other. The result is a cracked material, and at the same time, it can be stably fixed after the lock and has a better anti-loosening and anti-backing effect.
