Each of the cones 531 has a roll surface 5311 extending outward from the rod body 52, and is connected to the roll surface 5311 and mutually Corresponding to the upper and lower inclined surfaces 5312 and 5313, the first inclined surface 5315 is formed at the intersection of the inclined surface 5311 and the inclined surface 5312. The inclined surface 5311 is adjacent to the inclined surface 5313. Forming a second tooth front 5316, and a third tooth front 5317 is formed at a position where the first inclined surface 5312 meets the lower inclined surface 5313, and the first, second, and third teeth 5315, 5316, A tip 5314 is formed at the junction of the 5317, and the third tooth 5317 is tapered from the tip 5314 and abuts to the roll surface 5311 of the other cone 531.

參閱圖5、圖6，鎖合時，透過該螺牙53切削該物件6的過程中，該尖端5314與該第一、第二牙鋒5315、5316分別斬切該物件6，以使該物件6之木纖維(如圖6之假想線條)可經由該第一、第二牙鋒5315、5316而斬斷，並且該第三牙鋒5317將順著該尖端5314於該物件6上鎖旋 切出之一鎖合軌跡，而後該第三牙鋒5317將依循該鎖合軌跡進入該物件6內，將可降低該第三牙鋒5317、上傾面5312、下傾面5313與該物件6之接觸面積，減少該物件6與該第三牙鋒5317、上傾面5312、下傾面5313旋切過程所產生之摩擦力，同時該上、下傾面5312、5313與該第三牙鋒5317處將與物件6間形成有一容置空間61，以供鎖合過程所產生的切屑可排入該容置空間61內，將可避免切屑無處可排而造成後續鎖合之阻力外，同時亦可避免該切屑相互擠壓而產生該物件裂材之情事，進而達到降低鎖合阻力、增加鎖合速度與防止裂材等功效外，同時當旋鎖至另一錐體531時，該錐體531之第一、第二牙鋒5315、5316又可再次針對該物件6與該容置空間61內之切屑再次斬斷粉碎，粉碎後之切屑在排入該錐體531與物件6所形成之容置空間61內，如此透過該等錐體531之設置，將可使鎖設過程越鎖越省力與順暢；此外，當旋鎖完成後，由於該側傾面5311與該等容置空間61內皆填滿該切屑，如此當該物件6受到外在因素震動(如搬運、地震、使用中)時，經由該側傾面5311與該容置空間61之切屑卡掣，將可避免該螺絲3產生旋退，使得鎖設效果更佳、更穩固。。Referring to FIG. 5 and FIG. 6 , in the process of cutting the object 6 through the screw 53 , the tip 5314 and the first and second teeth 5315 and 5316 respectively cut the object 6 to make the object. The wood fiber of 6 (the imaginary line of FIG. 6) can be broken by the first and second teeth 5315, 5316, and the third tooth 5317 will be locked on the object 6 along the tip 5314. One of the locking trajectories is cut out, and then the third tooth 5317 will follow the locking trajectory into the object 6, which will lower the third tooth 5317, the upturned surface 5312, the downwardly inclined surface 5313 and the object 6 The contact area reduces the friction generated by the object 6 and the third tooth 5317, the upturned surface 5132, and the inclined surface 5313, and the upper and lower inclined surfaces 5312, 5313 and the third tooth front At 5317, an accommodating space 61 is formed between the object and the object 6, so that the chips generated by the locking process can be discharged into the accommodating space 61, which can avoid the resistance of the swarf and the subsequent locking. At the same time, it is also possible to avoid the fact that the chips are pressed against each other to produce the material cracking material, thereby achieving the effects of reducing the locking resistance, increasing the locking speed and preventing the cracking material, and simultaneously, when the lock is locked to the other cone 531, the The first and second teeth 5315 and 5316 of the cone 531 can again be crushed and crushed again for the object 6 and the chips in the accommodating space 61. The pulverized chips are discharged into the cone 531 and the object 6. Formed in the accommodating space 61, such that the setting of the cones 531 can be locked The more the lock is more labor-saving and smooth; in addition, when the twist lock is completed, since the roll surface 5311 and the accommodating space 61 are filled with the chip, the object 6 is subjected to external factors (such as handling, earthquake). When in use, the chip 3 of the accommodating space 61 via the roll surface 5311 can prevent the screw 3 from being retracted, so that the locking effect is better and more stable. .
