Description of the Invention: [Technical Field] The present invention relates to a screw structure improvement relating to a screw structure which is designed to tap and scrape on a workpiece to achieve a fast locking function. [Prior Art] Screw is an indispensable tool in the toolbox, and it is called the biggest gizmo, except that the screw structure and the screwdriver are closely related to the development history of science. Moreover, the screw is inconspicuous in the daily life of modern people, but It is a locking component that deeply affects everyone's life. From small jewelry parts to cars and buildings, you can see the traces of screws. This shows the importance of screws for human development and life. 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 threaded holes in the wood or large building materials to bite the holes drilled by the screw tips, in wood or The workpieces such as large-scale building materials are broken and squeezed into the internal threads corresponding to the gas-producing strips, and then advanced into the workpieces such as wood or large-scale building materials to achieve the goal of [0001] [0002] Ο [0003] [ [0004] 099100046 The conventional screw thread is set on the edge of the nail body and the shape is symmetrical. The resistance during the hole-hole process increases with the thread of the screw. Because the filament is drilled into wood or large building materials, in addition to the resistance of the new thread created by the extrusion and destruction of the wire, the frictional force of the thread advances, plus the addition of debris and powder during the screwing. Friction, the force required to screw into the screw increases with the depth of the screw. In addition, if the user uses the automatic tool for labor saving and time saving, the automatic tool will reduce the timing of the _ situation. Form No. A0101 咕w "Page 3 / Total 16 Pages 0992000130-0 [0005] 201124640 Resistance When the force is applied too much, the screw is broken, and the resources such as the workpiece and the screw are wasted, and the nail head is ejected, and the nail head is ejected. [0007] [0007] In view of the above drawbacks of the conventional screw, the inventors directed The screw body is deeply researched, and the screw structure is designed to improve the effect of thread drilling from the mechanical point of view. The compound thread can improve the efficiency of drilling and tapping, reduce the locking time, and use chip removal. Reduced friction' becomes a screw that saves time and effort and is convenient for operation. The screw structure of the invention is improved, including a nail head and a nail body, wherein the nail body includes a cone tip and a cylinder body, and four screw teeth are arranged around the cone tip. A thread is an asymmetrical thread, the front end angle α of the thread of the asymmetric thread is between 30 and 40 degrees, and the rear end angle is cold between 10 and 20 degrees; the second thread is connected between the cone and the cylinder. Second thread The V-shaped cutting tail is a groove at least one pitch length along the direction of the nail body, forming a space for accommodating the debris and powder of the front end hole, and discharging the debris and the powder to the rear end; the third thread The taper tip and the cylinder are connected to the rear end of the cylinder, which is a protruding serrated thread, and the tooth pitch is the same as that of the first screw. The front end angle α' of the thread is between 27 and 33 degrees, and the rear end angle is Cold 'between 7 to 13 degrees, when the nail body is extended from the tip of the cone to the column, the effect of drilling and grinding is increased by the sawtooth thread, the fiber of the workpiece such as wood is cut and the hole is enlarged. The nail is advanced; the fourth screw is disposed on the third screw, which is an asymmetrical thread, the front end angle α of the screw, between 27 and 33 degrees, and the rear end angle, between 7 and 13 degrees, and The tooth pitch 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 effect of the advancement of the nail body. $, the invention can discharge the chips and powder, and reduce the body of the nail. Friction, save time and effort, the effect of broken 099100046 Form No. 1010101 Page 4 / Total 16 pages of coffee 2〇〇〇13〇_〇201124640 [0008] The invention has the following advantages: [0009] 1. The screw structure of the invention is improved, and the outer edge of the screw body of the screw structure is provided with asymmetrical screw teeth and serrated teeth, which can increase the efficiency of drilling and tapping, and save the province. 2. The effect of the invention is improved. The screw structure of the 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 invention is improved, and the screw provided can discharge the debris and the powder. The frictional force during drilling is reduced.
