請閱第一圖所示，其係申請人所申請之中華民國第M334215號之一種習知木螺絲，該木螺絲9係由一桿體91之第一端設有一螺頭92，該桿體91之第二端設有一尖錐部93，該桿體91近尖錐部93段設第一螺牙94，該桿體91近螺頭92段設第二螺牙95，及該第一螺牙94與第二螺牙95之間具有一突牙96，該第一螺牙94與第二螺牙95呈螺旋狀且反方向地設置，該突牙96於同一平面成環設於該桿體91上，如此，可以防止如習知單一螺紋之螺絲受外力震動而隨著螺紋的反方向鬆脫，且在旋合過程當中，該第一螺牙94所旋起的殘屑，可以受到突牙96之阻擋，並藉由相反方向的第二螺牙95形成切割，以免除該殘屑纏繞糾結在一起的困擾，及使該殘屑成密實的存在第二螺牙95之牙槽當中，使該木螺絲螺合時可降低其鎖合阻力及提高穿透力。 Please refer to the first figure, which is a conventional wood screw of the Republic of China No. M334215 filed by the applicant. The wood screw 9 is provided with a screw head 92 at a first end of a rod 91. The second end of the 91 is provided with a tapered portion 93. The first protruding thread 94 is disposed on the proximal tapered portion 93 of the rod body 91. The second screw 94 is disposed on the proximal portion 92 of the rod 91, and the first screw is disposed. Between the tooth 94 and the second thread 95, there is a protruding tooth 96. The first thread 94 and the second thread 95 are spirally arranged and oppositely arranged. The protruding teeth 96 are looped on the same plane. In the body 91, in this way, it can be prevented that the screw of the single thread is loosened by the external force and loosened in the opposite direction of the thread, and during the screwing process, the debris swept by the first thread 94 can be subjected to The teeth 96 are blocked, and the cutting is formed by the second thread 95 in the opposite direction, so as to avoid the trouble that the debris is twisted and entangled, and the debris is densely formed in the socket of the second thread 95. When the wood screw is screwed, the locking resistance and the penetration force can be reduced.

請閱第二圖所示，其係中華民國第M463785號所揭示之螺絲，該螺絲8係由一桿體81之一端為***端82，該桿體81之另一端為頭端83，該***端82具有至少一割尾槽84，該桿體81之下段概呈正三角形的橫向斷面且具有一第一螺牙85，該第一螺牙85包含複數不對稱的螺牙，該桿體81之上段具有圓形的橫向斷面及一第二螺牙86，該第二螺牙86係 呈螺旋狀地設在桿體81的上段且包含複數螺牙，第二螺牙86之上旋方向與第一螺牙85之上旋方向相反。該螺絲8藉由割尾槽84與斷面呈三角形的下段設計，可有效且快速地切削複合板材以鎖入工件中，且複合板材的廢屑亦可沿著割尾槽84及三角形斷面之下段導出，可以降低螺絲8在鎖入方向的阻力。且當該螺絲8鎖入複合板材中時，與螺絲8接觸的複合板材部份在產生向上擠之情形下，可以藉由反向旋繞設計的第二螺牙86將向上擠的部分下壓，可以達成密實結合的效果。 Please refer to the second figure, which is a screw disclosed in the Republic of China No. M463785. The screw 8 is formed by one end of a rod 81 as an insertion end 82, and the other end of the rod 81 is a head end 83. The end 82 has at least one tail slot 84. The lower portion of the rod 81 has an equilateral triangular cross section and has a first thread 85. The first thread 85 includes a plurality of asymmetrical teeth, and the rod 81 The upper section has a circular transverse section and a second thread 86, the second thread 86 The upper portion of the rod body 81 is spirally formed and includes a plurality of threaded teeth, and the direction of rotation of the second thread 86 is opposite to the direction of rotation of the first thread 85. The screw 8 is designed by cutting the tail groove 84 and the lower section with a triangular cross section, and can effectively and quickly cut the composite plate to lock into the workpiece, and the scrap of the composite plate can also be along the cutting groove 84 and the triangular section. The lower section is exported to reduce the resistance of the screw 8 in the locking direction. And when the screw 8 is locked into the composite sheet, the portion of the composite sheet that is in contact with the screw 8 can be pressed upward by the second screw 86 of the reversely wound design in the case of upward squeezing. A compact combination can be achieved.

按，上述二種習知螺絲通常被使用於木材、塑膠等非金屬材質的板材結合，且由於該螺絲之***端具有割尾槽，因此，使用該習知螺絲時，可以藉由該割尾槽形成自攻螺絲，且當該習知螺絲旋合至該第二螺牙與板材接觸時，該第二螺牙可以阻擋該板材之殘屑繼續排出，並形成向下壓擠的使殘屑存留在第二螺牙的牙槽當中，如此，可以使該螺絲確實的定位於被結合的板材當中。然而，在該殘屑無法排出情形下，繼續對該螺絲旋轉時，該殘屑將形成一阻力，使該旋轉工作變得困難螺絲，甚至造成該習知螺絲無法繼續深入問題。 According to the above, the two conventional screws are usually used for joining non-metallic materials such as wood and plastic, and since the insertion end of the screw has a cutting groove, when the conventional screw is used, the tail can be used. The groove forms a self-tapping screw, and when the conventional screw is screwed to contact the second screw with the plate, the second screw can block the debris of the plate to continue to be discharged, and form a downward crushing It remains in the socket of the second thread, so that the screw can be positioned exactly in the bonded sheet. However, in the case where the debris cannot be discharged, when the screw is continued to rotate, the debris will form a resistance, making the rotation work difficult to screw, and even causing the conventional screw to continue to go deep into the problem.
