New description: ., [Technical field of new type] This kind of creation is related to a kind of screw, especially related to one wire. < [Prior Art] Reference! Figure, a conventional wood screw (10) contains = and a rod 12 〇. Screw head u. It is used to connect with the locking device: the cup n m is extended by the screw head 110, and the flat body portion 124 and a tapered portion 122 formed at the parallel rod body portion 124 are formed. The material is formed with a thread 13 于 on the parallel cone portion 122. Eight of the above-mentioned wood screws 100 are intended to be locked in: Wood:: Screw directly into a piece of wood. However, the snails from the parallel rods 124 and the threads 130 and the wood B have gradually increased the rubbing force, and it is required to have more and more screwing torque, and the wood chips generated by the A grain cutting shaft do not have the wood W." Also make|has:: composite material of elastic plastic and wood genus, because of the goodness and tightness of the 'screw 1G. In the lock man, the compound phenomenon is difficult to draw on the thread 130, and it is easy to idling. For hardwood floors, such as When the rosewood, walnut, etc. are locked on the general cork backboard, the hardwood floor is hard and strong, resulting in a slow drawing of the screw 100. Further, when the thread 130 is screwed into the cork backboard by the hardwood floor, Since the thread pull in the cork is not enough to allow the screw head 110 to sink into the hardwood floor, it takes a lot of force to sink the screw head 110 into the hardwood floor, and it is also prone to cracking. In view of this, there is a need A screw is proposed to solve the above problem. [New content] The present invention provides a wood screw. The wood screw of the first embodiment comprises a screw head, a rod, a first thread, at least a second thread and a third thread. The screw head is connected to the locking tool, and the rod body is extended by the screw head, has a parallel rod portion, is formed at the end of the parallel rod portion and is tapered. a tapered portion, and a tip formed at an end of the tapered portion. The first thread is formed in a large cone (5 forces and extends from the tip. The third thread is formed on the parallel rod portion, and The second snail is formed on the tip I5 knife and is located between the first and third threads, wherein the second spiral direction is opposite to the spiral direction of the second thread, and the first and second The third threads are not connected to each other. The wood screw of the second embodiment of the present invention has a structure similar to that of the second embodiment of the gas, but the original helical second thread is changed to a plurality of ribs. The wood screw of the third embodiment is created to have a structure similar to that of the first embodiment screw, but the original spiral second thread is changed to a love-shaped mesh pattern. For example, the wood screw of the fourth embodiment is created. The structure of the first implementation screw, but the original helical second thread is changed It is a hard number of irregular protrusions. According to the wood screws of this creation, the surface of the wood can be quickly taken during the first snail wood. The second two-input pattern and the protrusion can be cut into the wood block: wood fiber, with a drop == screw in Torque 'and prevent the wood from cracking. The third thread force. Therefore ° toothed 'to provide a pull-proof material to prevent pull out 1 according to the creation of the wood screws can be locked to a variety of wood such as various cork, hardwood, extremely hard Sawdust, sinter or resin and soft and hard composite materials synthesized from wood. ~Wooden: C for the above and other purposes, features and advantages. In addition, the second part of the accompanying drawings is described in detail below. In the description, the H structure (4) (10) is not described, and the description will be made first. [Embodiment] The present invention includes the wood screw 2 of the first embodiment of the present invention. The freckle lock is: 10: and a rod 220. The head 210 is used to connect, and the rod 22 is defined by the stomach 210 π# and defines an axis (a rod 22). == M407970 The body portion 224, a tip portion 222 forming a "parallel rod portion 224 end and tapered, and a tip end 226 formed at the end of the tip portion 222. A third thread is formed on the parallel rod portion 224. 230, which is engageable with the wood to provide a tensile force that prevents pull-out. The wood screw 2 has a first thread 24 that extends from the tip 2% and is formed on the tapered portion 222. Also formed on the tapered portion 222 is at least one second thread 250 that is not extended by the tip end 226 between the first thread 24 〇 and the third thread 230 and extends to the parallel shank portion 224 'and The spiral direction of the second thread 250 is opposite to the spiral direction of the third thread 230, and the threads 23〇, 24〇, 25〇 are connected to each other. The second thread is 25〇$ lead angle ange) 02 max. The lead angle of the third thread 23〇 is second, the lead angle Θ1 of the second view (10) is the smallest. The outer diameter of each thread is compared with the thread of the thread 250 of the second thread 23〇 (fourth), Take the first - to take the big brother, the second line of D1 is the smallest. In addition The first "text spiro ^ buckle 230 may be symmetrical or asymmetrical tooth teeth. “4〇 and the third thread thread 240 have a small lead angle, and the wood screw can be quickly drawn from the wood surface. In addition, the second paragraph 25=simple desired direction (four)^ becomes 230 lock After entering the wood, the second thread 250 reduces the function of the wood fiber in the 20 wood blocks of the wood snail. It can screw in the force of 4 200 and prevent the wood from cracking. The screw is successfully locked with M407970, which is in line with the user. The best expectation is that the wood screw 200 preferably comprises three second threads symmetrically formed on the tapered portion 222, and the complex & cut surface can form a triangular position. Thus, it can further be desired by the user. The direction is quickly screwed into the wood to achieve a better locking effect. And the right class 2 3 Figure 'The second embodiment of the wood screw 300 phase Lr tired wire 200 structure, the same number indicates the same 70 In the present embodiment, the original spiral second chip 2-50 is changed to a plurality of ribs 35 (), and the ribs are either lined or not parallel to the axis 290. Wood screws say that the ribs are 350, and there are reaming holes in the middle, the function of wood fiber can be reduced. Cloth ^ 3〇〇 screws into force 'to prevent the wood alkylene cracked' in order to achieve a successful lock screw &, the user to pay the optimum desired bonding.
