Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a screw design, and more particularly to a low-resistance screw with a high cutting speed and high strength. [Prior Art] Referring to Figures 1 to 3, the conventional screw 1 of the U.S. Patent No. 2/5, 186, 48 includes a screw head 11, a rod 12 extending from the screw head 11, and a plurality of spiral rings. a thread 13 disposed on the rod body 12, and a locking portion 14 disposed on the rod body 12 opposite to the thread head; wherein the screws 13 are provided with a plurality of connected slits (3) In particular, the threads u and the upper and lower ridges 132, 133 intersect with a peak angle a (about 3 degrees of illusion, and the apex 135 formed by the outer peak 134 is disposed on the slit (3). a top angle a, (about 30 degrees to 58 degrees), and the cutting step is formed into a slit angle; therefore, the conventional screw 1 can utilize the turning function of the slits (3) to enhance the angle The action of the snail 13 cuts the object to achieve the quick-locking positioning effect. However, after the actual use, it is found that the screw 13 is locked into the object 2, although the setting of the slit 131 can provide a better cutting effect, but , the angle of the incision angle of the incision 131 <the size of the lunar scorpion and the angle of the angle of the auger 13 •^ tooth peak a, etc. The part is easy to influence the screw-locking effect. The following analysis is as follows: h Firstly, for the angle of the angle A of the notches: the cutting ability of the threads 13 is affected by the degree of the angle of the notches. That is, if the angle of the angle A of the incision A is set to be too small, the thread 13 is cut by the needle to perform a quick lock, and when the object 2 is moved, the fiber of the object 2 cannot be one by one due to the characteristic of elastic restoring force. The entry into the slits (3) causes the slits 131 to fail to provide the function of assisting the rotation of the object 2, so the cutting ability of the slits (3) is limited or even ineffective, and the screw cannot be guided. If the angle A of the slit A is opened, the size of the thread 13 may be relatively reduced. On the contrary, the angle of the slit A is too large, and the cutting ability of the slit (3) is not as good as the angle of the slit. Eight small turning ability, and the size of the thread of the thread is relatively weak due to its structural weakness*, resulting in insufficient torque and easy to have a broken tooth, and it is worth improving. The design of the peak angle a of the thread 13 of the thread 13 is: The angle of the tooth peak of the thread 13 is owed to the angle of the tooth peak of the thread 13 and is different depending on the size of the angle, that is, if the thread is different If the angle a of the peak is too small, the (10) tooth 13 may have a better cutting ability, but when the screw 13 encounters a (four) hard object, the pole (4) the screw 13 cannot withstand a large twisting force, so that the When the thread 13 is locked in the process of locking the person, when the tooth peak of the thread 13 is out of angle: when the thread 13 is large, the material 13 can be purely subjected to the torsion force. The effect is not as small as the angle of the tooth peak. Screw teeth, so there are restrictions on their use, there is room for improvement. [Inventive content] 201139869 The effect of the lock. In the present invention, the lock low-resistance screw of the present invention comprises a screw head, the rod body of the screw head is provided with a plurality of spiral rings on the rod body, and a lock opposite to the screw head and disposed on the rod body Each of the first thread has a first ', a 孑 面 surface, and a first lower peak surface that is continuous with the first upper upper peak surface; the upper tooth peak The intersection of the surface and the first lower peak surface intersects with a first peak angle; in particular, the spiral ring on the rod body is provided with a plurality of second thread, and the system is divided into the upper tooth peak a surface of the first and lower teeth; wherein the second thread has a second upper peak surface and a second lower peak surface connected to the second upper peak surface; the second The intersection of the upper tooth peak surface and the second lower tooth peak surface intersects with the second tooth peak angle; at the same time, the second upper tooth peak surface and the second lower tooth peak surface are opened with a plurality of relative opening a slot; and the angle of the first peak is smaller than the angle of the second peak; so when the lock is engaged, the slot is effectively cut and the chip is disposed, and the first screw is disposed on the first thread second The method of interdental, and the angle of the first peak is smaller than the angle of the second peak to enhance the strength of the second peak, and the cutting ability of the low-resistance screw is further improved to achieve quick locking efficacy.
