[Prior Art] [0002] Screw is an indispensable tool in the toolbox, and it is called the largest gizmo, except that the screw structure and the screwdriver are closely related to the development history of science. Moreover, the screw is not in the daily life of modern people. Eyes, but it is a locking component that deeply affects everyone's life. As small as the car's jewelry parts, as far as cars and buildings, you can see the traces of the screws, which shows the importance of screws for human development and life. [0003] However, screws used for construction and the like are used for workpieces such as wood or large building materials, and are drilled into the surface with screw tips, and the holes drilled by the screw tips are tightly threaded on the workpiece such as wood or large building materials. In the case of wood or large building materials, the corresponding internal thread is broken and squeezed, and then screwed into the interior of the workpiece such as wood or large building materials to achieve the purpose of screwing. [0004] The conventional screw thread is placed on the edge of the nail body. And the shape is symmetrical, the drilling process _ resistance will increase with the screw thread. When using screws to drill into workpieces such as wood or large building materials, in addition to the resistance of the new thread created by the extrusion and destruction of the tip, the frictional force when the thread advances, plus the friction caused by the debris and the powder during the screwing. Force, causing the force required to screw into the screw to increase with the depth of the screw. [0005] In addition, if the user uses the automatic tool for labor saving and time saving, the automatic tool can reduce the user's grasp of the screw condition, and it is difficult to detect 1013207598-0 09910004^^^ A0101 ^ 3 1 / ^ 15 1 1375757 [0006] [0007] On the 10th, 5th, and 5th of March, the increase of the resistance of the replacement page is increased. When the force is too large, the screw is broken, and the resources such as the workpiece and the screw are wasted, and the 4T head is popped up. In view of the defects of the above-mentioned conventional screws, the inventors made in-depth research on the nail body of the screw, and designed the screw structure to improve the effect of the thread drilling ceremony from the mechanical point of view, and improve the efficiency of the drilling and tapping with the compound thread. , to reduce the lock time, and reduce the friction by the chip evacuation 'to become a time-saving and effort-saving screw. The screw structure of the invention is improved, comprising a nail head and a nail body, wherein the nail body comprises a cone tip and a cylinder body, and four screw teeth are arranged around the cone, and the first thread of the cone tip is an asymmetrical thread, the asymmetrical thread The front end angle α of the thread is between 30 and 40 degrees, the back end angle is between 1 and 20 degrees; the second thread is connected between the cone and the cylinder, and the second thread is a V-shaped tail. The groove of the nail body at least one tooth length length forms a space for accommodating the debris and powder of the front end hole, and can discharge the debris and the powder to the rear end; the third screw is made up of the cone tip and the cylinder body The joint extends toward the rear end of the cylinder, which is a protruding ore tooth, and its pitch is the same as that of the first thread. The front end angle α of the thread is between 27 and 33 degrees _ - - - - ' At 13 degrees, when the nail body is extended from the tip of the cone to the cylinder, the effect of drilling and grinding is increased by the sawtooth thread, and the fiber of the workpiece such as wood is cut and the hole is enlarged to advance the nail body. : The fourth screw is set behind the second screw, which is an asymmetrical screw. The front end angle of the screw is α, between 27 and 33 degrees, and the back end angle is called, between 7~ 13 degrees, and the tooth distance is the same as that of the first screw and the third screw, and the internal thread drilled by the third screw can be connected to increase the advancement of the nail body. In addition, the invention can discharge debris and powder, reduce the friction of the needle body, and achieve the effect of saving time and labor.

The screw structure of the present invention Improved, with asymmetrical thread and serrated thread on the outer edge of the screw, it can increase the efficiency of drilling and tapping, and achieve a time-saving effect. 2. The screw structure of the present invention is improved, and the V-shaped cutting tail forms a blade portion, which can increase the drilling efficiency. 3. The screw structure of the present invention is improved, and the screw provided can discharge the debris and the powder to reduce the frictional force during drilling. [Embodiment] [0010] Referring to Figures 1, 2, and 3, the screw structure 1 of the present invention includes a body 2 and a nail head 3, wherein: [0011] the body 2 includes a coaxial a taper tip 21 connected to the line and a column 22, wherein the taper tip 21 is provided with a first thread 23, which is an asymmetrical thread, and the front end angle α of the thread of the first thread 23 is between 30 and 40 degrees. The end angle is cold between 10 and 20 degrees; the second thread 24 is connected to the cone 21 and the second thread 24, and the second thread 24 is a V-shaped tail, which is concave along the length of the nail body 2 at least one pitch length. The groove 241, the edge of the groove 241 forms a sharp edge portion 242; the third thread 25 extends from the tip end of the cone 21 to the rear end of the column 22, and is a protruding serrated thread, the third thread 25 is an asymmetrical thread, the front end angle α' is between 27 and 33 degrees, the rear end angle is cold 'between 7 to 13 degrees, and the pitch is the same as that of the first thread 23; the fourth thread 26 is set at After the third screw 25, the fourth screw 26 is also an asymmetrical thread, the front end angle α' 'between 27 and 33 degrees, and the rear end angle is cold ' ' between 7 and 13 degrees, and the tooth pitch thereof It is the same as the first screw 23 and the third screw 25.面##单编号删1 Page 5/15 pages 1013207598-0 1375757 101.05.31. Nuclear replacement page [0012] Please refer to Figure 1, Figure 3 and Figure 4, The nail head 3 is extended by the same axis of the nail body 2, and is a disk-shaped body; the gas portion is connected to the last end of the nail body 2, and the rear end surface of the nail head 3 is provided with a quadrangular groove 31, and the corresponding A tool such as a screwdriver is rotated. [0013] Referring again to FIGS. 1 and 2, when the screw structure 1 of the present invention is used, the tip of the taper tip 21 is inserted into the workpiece to prevent the screw structure 1 from sliding or moving, and the first screw 23 is used.
