New description: [New technical field] The new type is related to a 蟫 silk design, especially a kind of fast cutting screw. 〃 [Prior Art] Referring to Figures 1 and 2, the conventional wire + + wire 1 includes a screw U extending outwardly from the screw head; a body 12, and a plurality of spiral rings are disposed on the body 12 threaded teeth 13 . < When the lock is engaged, a torsion force is applied to the screw head u to interlock the thread teeth 13 to cut the object 2, and gradually drive the rod body 12 into the object 2 In order to achieve the effect of the lock positioning. However, after actual use, it is found that since the thread 13 is circularly wound around the rod body 12, the thread 13 is in close contact with the object 2 during the cutting process, except that the thread is caused. 13 and the frictional force of the object 2 is increased, and the chips generated by the cutting are easy to accumulate and cannot be smoothly discharged outside the object 2, so that the locking resistance of the screw 增加 is increased, and the locking torque is greatly increased, so the relative When the screw 1 is locked, it must be applied with a larger locking torque to lock it. The resulting locking speed will also be affected and reduced. At the same time, when the chips are accumulated to a certain extent, the chips are easily squeezed to form each other. The situation of outward pressure expansion has caused the situation of the object 2 to be cracked and the situation needs to be improved. [New content] Therefore, the purpose of the present invention is to provide a fast-cutting screw M413036 wire which has the functions of quick screwing, lowering the locking torque, and reducing the cracking of the object in the locking. Thus, the novel screw with rapid cutting comprises a screw head, a rod body extending outward from the screw head, and a plurality of spiral rings.

It may be arranged in parallel as shown in FIG. 3 or in an inclined ring shape as shown in FIG. 5, and the following embodiment is only described by taking a parallel arrangement as an example; and 5 M413036 is the 'chord-cutting arc 331 of the screw 33. The length may be symmetrical equal length, or as shown in the embodiment of FIG. 6 and the following, and the design is asymmetrical and unequal in time; it is worth mentioning that, in addition to the string cutting arc 331, the connection of the screw 33 A plurality of openings 333 are formed in the string 332 so that the thread 33 has a zigzag shape as shown in FIGS. 8 and 9. Referring to FIG. 3, FIG. 6, FIG. 7', when the screw 3 is locked to the object 4, since the screw 33 forms an approximately elliptical non-circular shape, when the screw 33 cuts the object 4, Only the string cutting arc 331 formed near the pole p will contact the object 4, so that the contact area between the screw 33 and the object 4 can be reduced to reduce the friction, and at the same time, during the drilling process, The chip evacuation space 41 is formed between the screw 33 and the object 4, so that the chips generated during the cutting process can be quickly discharged through the space of the chip evacuation space 41, in addition to avoiding chipping due to chipping. The external extrusion causes the anvil of the object 4 to be cracked, and the resistance generated by the twist lock can be reduced, thereby achieving the effect of reducing the locking torque and effectively increasing the locking speed. Continuing with the above description, when the chord-arc 331 is of unequal length compared with the existing round-shaped screw, the locking can reduce the contact area between the screw 33 and the object 4, and at the same time The thread 33 having the asymmetrical string-cut arc 331 and the object 4 form an accommodating space 41 and complement the shape of the thread 33 so that the accommodating space 41 can be used not only for the shoulder but also for the thread. 33 and the chip will produce mutual balance force 'to make the chip can be placed in the present, so that the screw 3 locks the anti-back effect is better; another, # does not live, and, when the screw 33 is connected When the chord 6 M413036 332 is formed with the opening 333 in time to form a mineral tooth shape, the chips wrapped around the thread 33 and the string cutting arc 331 can be effectively cut and provide a part of the chip receiving and lifting row. The chip effect, so that the screw 3 is more easily screwed into the object 4, and the locking speed is improved.
