Users can quickly drill this creation screw into harder wood or with low torque. Those who have good chip removal and locking strength at the same time can avoid wood cracks or cracks, and achieve safety test of labor-saving construction and locking force, which can greatly reduce the construction time. [Previous technology] In recent years, there has been an increasing trend in the construction of wooden houses. The requirements for the quality of wood have become more stringent. Even the hardness of the wood, even ordinary iron nails, can be entered by iron hammers and less than three points. A depth of one, then bend, if the screw is used for construction and locking, but the wood is too hard, the wood cannot be squeezed when the screw is screwed in, and the locking is difficult to break, even if it can be tightened smoothly. It has been subjected to high torsion and rotated and deformed. After a period of time, the internal fracture automatically due to stress is unknown but therefore, the current construction method must drill holes and screw in screws for thicker wooden boards in order to overcome this construction problem. Reduce the construction time and study the feasibility of using the improved screws directly. As shown in the first figure, it is a general ordinary screw & it enters from the tip al when screwing into the wood, and then pulls in when it contacts the initial screw a2. The wood is gradually opened by the slope a3. Due to the force of spreading, the leanness of the wood is pushed up to the highest point a4. The density of the wood cannot withstand the pushing and cracks or cracks. The degree of cracking will be greatly related to the thickness, width and fiber direction of the wood. The thickness is thin, the width is narrow, and the cracking is the most serious. If it happens that the wood fiber is a vertical plane, this piece of wood is bound to fail. M273640 Jian Jian surname Gou ^ is a horizontal plane, and the wood is also insufficient due to cracking or cracking. If the size of the wood and the width of the wood are large, the wire holes on the surface of the surface will gradually produce traces, and the long fiber will be locked into the cracks of different sizes. As the screw a has broken, the resulting spin The larger the torque is, some screws ^ until the a5 part of the screw head is completely locked into the plane of the wood.

而排屑槽19因螺絲桿體12旋入愈深，排屑槽19内之木屑將 因牙底14、牙山15互緊密合而擠壓由排屑槽19不斷推擠上 升，在推擠上升過程中，為緩衝排屑槽19的壓力，在排屑 槽19另一方向，也就是牙底14設置了緩積槽18，該緩積槽 18除了使螺絲桿體12在旋入時，增加其扭轉角度及螺絲彈 力外，更提供了木屑另一容積空間，緩解了牙底14、牙山 _ 15在鎖合木材過程中，因木屑之增加所增加之旋入扭力，

is only limited to the bottom diameter b3 of the slotted screw b. During the screwing process, the slot b2 will have no effect due to the increase of the drilling depth (about 15m / m or more), resulting in the short screw wood as described above. Small, long screw wood cracks are the same phenomenon around the screw hole, the torque reduction is limited, and the stress is also present. As shown in the second picture, it is a kind of wood screw C disk. The second picture is roughly _, but-no _ is the addition of a thin knife c51. The cutter c5 is made of wood screws 3 to 5 teeth from the bottom. Straight and evenly arranged on the circumference of the tooth base c3 'There is another type of diagonal spiral upwards and evenly arranged on the diameter of the second base C3 circle, the purpose of which is to use a cutter added to the tooth base C3. 5 As a function of cutting 'attempt to cut the fiber of the wood to reduce cracking, it is not true of M273640' In the experiment, the cutting edge c5 arranged at the bottom of the tooth c3 has a height of only 0.2 · 0.4 m / m '2. Conversely, because the height difference η between the tooth base 牙 and Asan c4 is the most important part of the screw tightening tension, the cutting edge C5 protruding from the tooth base c3 reduces the height of η, which will seriously affect the screw (3 Adhesive force or locking force is used. The fourth picture shows that it is a drill-drilled screw d, which is used for drilling into iron plates and locking, and is used for roof paint panels and wall outer plates. On the fastening of the wood, it is known through actual tests that when drilling the screw d into the wood, the tail point dl is designed for the iron plate. When drilling, it is cut into the hard wood with two wings # notch d2 ' It is easy, but its tip is not threaded and cannot generate pull-in force. You must continue to apply force to the tool to press the screw d to continue drilling. Therefore, the screw d3 must be screwed into the wood to produce the screw-in action. And the thread must be made as iron plate coarse teeth or wood screw coarse teeth. Barely used, but manual tools are not available. Electric tools must be used to generate extremely fast rotation speeds as construction tools. The drilling depth is about 30m / m. There is no crack in the wood. Above 30m / m, the crack increases with the drilling depth. And increase, so the problem of cracking on the use of long-size screws also exists. [New content], four types of screw design, each has a special effect, but, in order to apply to a variety of construction wood, the screw must have The following effects: 1. It is easy to drill into hard woods, even iron plates. 2. It is necessary to avoid cracking or cracking of wood. 3. The screwing torque is low to achieve labor-saving construction conditions. 4. The adhesion is increased and the locking force is increased. It is important to consider safety. 7 M273640 5. It has the tip of the spin for fast locking. This creation-a kind of screw improvement, which mainly has a head and a head-the neck is not connected to the rod, and it is oriented toward the rod. The bottom of the screw is smaller than the outer diameter of the rod body, the outer diameter of the mountain is larger than the outer diameter of the rod body, and the iron milling section is set at the end of the drill and milling section as the tip of the recording. It is characterized in that- There are several slow accumulation grooves on the mountain—or shavings. The shaft of the drilling and milling part is larger than the bottom of the tooth and smaller than the ridge of the tooth. One or more cuts are formed on the drilling and milling part to form one or several drilling and milling wings. The tooth: The slope is provided with a material. The material is attached to the tip of the tooth tip, so as to form a quick-drilling, fast chip removal, and adhesion effects-a kind of screw Chengliang 'users can low torque Quickly drill this creative screw into harder wood or iron plate, and at the same time have good chip removal and locking force to avoid wood cracks or cracks and achieve safety considerations of labor-saving construction and locking force, which can greatly reduce the construction time [First embodiment] Please refer to the fifth and sixth figures, a screw modification, which mainly has a head 10, a neck u below the head 10 is connected to the rod body 12, and the rod body 12 is provided with a screw 13 downward, the outer diameter of the bottom 14 of the screw 13 is smaller than the outer diameter of the rod body 12, the outer diameter of Asan 15 is larger than the outer diameter of the rod body 12, and a drilling and milling portion 16 is arranged at the lower end of the screw 13 The front end of the milling part 16 is provided with a pointed tooth tip 17, which is characterized in that: one or several numbers are provided on the tooth bottom 14 Slow accumulation grooves 18, one or more chip removing grooves 19 are provided on the yashan 15, the outer diameter of the drilling and milling portion 16 is larger than the bottom of the tooth 14 and smaller than that of the yashan 15, and one or more of them are opened obliquely on the drilling sharp portion 16. Each incision 20 forms one or several drilling and milling wings 21, and the inclination of the tooth tip 17 is provided with a guide screw tooth M273640 'to guide the entrance of the screw tooth 22 to the tip 23 of the tooth tip 17. The above-mentioned modification of a screw is as follows, wherein the guide screw 22 is set to 1 to 2 turns, the incision 20 is drilled into the milling part 16 from top to bottom, and the slow groove 18 is drilled to the bottom 14 from top to bottom. Inside, the chip removing groove 19 extends from Asan 15 to the bottom of the tooth 14 'The incision 20, the chip removing groove 19 and the slow accumulation groove 18 may be arranged obliquely or straight or spirally, and the incision 20, the chip removing groove 19 and the retardation groove 18 can be arc-shaped or right-angled. The drilling and milling wing 21 forms a sloped cutting edge 24 on the tooth tip 17 and forms a cutting edge 25 on the periphery of the drilling and milling portion 16, thereby forming a rapid A screw improvement such as drilling, fast chip removal, and adhesion. Those who use φ can quickly drill this creative screw into harder wood or iron plates with good chip removal and locking power, so as to avoid wood. Cracks or fissures and safety considerations for labor-saving construction and locking forces can greatly reduce construction time. Ben; ij director: for a screw improvement, when the tool is rotated from the tool hole on the head, the tip 23 is easily screwed into the wood by its sharp tail tip, because the entrance of the guide screw is attached to the tip 23, and the guide 22 Then the wood was screwed in, and the screw was gradually pulled in by the screw, and the thread was screwed to the second tooth. At this time, the wood has produced a squeeze φ, and the hole has been expanded. The slope side edge 24 has begun to cut the wood. Reduce the tension and continue drilling. The fine coffee on the wing 21 is up to the standard hole of the post, and the sharp cut 2G of 7725 is cut. At this time, the vertical plane of the timber and the straight side of the sheet are staggered with fibers. 20 rise to the chip flute 19, because the chip flute 19 is designed to penetrate through the bottom thread to the most f thread, so its wood chips rise from the chip flute 19 below, as the drilling depth increases At the time, the chip removal groove 19 not only has chip removal, the screw and the upper cut M273640 chamfer 27 can solve the expansion force generated when the screw 13 is screwed into the wood, and is rotated through the sharp point of the cutting angle 27 on the screw 13 Deep into the wood, while the inclined cutting edge 24 is continuously drilled into the large hole, the cutting edge 25 is continuously cut Wood chips, while the chip groove 19 is screwed deeper due to the screw rod body 12, the wood chips in the chip groove 19 will be squeezed by the tooth bottom 14 and Asan 15 close to each other, and the chip groove 19 will continuously push up and rise. In the process of pushing and ascending, in order to cushion the pressure of the chip removing groove 19, a retardation groove 18 is provided in the other direction of the chip removing groove 19, that is, the bottom 14 of the tooth, in addition to the screw rod body 12 being screwed in In addition to increasing its torsion angle and screw elasticity, it also provides another volume of wood chippings, which relieves the bottom of the teeth and Asan _ 15 in the process of locking the wood, due to the increased screwing torque due to the increase of wood chips. The torque does not increase. When the screw has been completely rotated into the wood, the screw cup body 12 is larger than the tooth bottom 14 but smaller than Asan 15, which can continuously increase the volume of wood chips around the screw rod body 12, which is calculated by The sawdust generated during the drilling of the half-screw is effectively discharged on the screw about 1/3, 2/3 are distributed around the rod body 12, and some are pushed into the wood, so the wood density will be higher than the original drill The hole increases when the hole is locked, and the slow accumulation groove 18 in the other direction of the chip discharge groove 19 is opposed and exhausted. In addition to increasing the elasticity of the twist when the screw rod body 12 is screwed in, when the chip discharge groove 19 is insufficiently discharged, the role of the slow accumulation groove 18 is used as a volume of wood chip space to ease the screw rod body 12 to cope with the unknown wood. At this time, the disadvantage that the chip discharge groove 19 cannot be deepened in advance is generated, and when a seller provides it to users, a very high percentage of users are free to use it. Therefore, when designing the product, the use scope and purpose of the screw should be clearly defined, and the depth and width of the chip removal groove 19 and the retardation groove have been based on the depth and width of the chip discharge groove 19 in the experiment. And adjust different depth width, said M273640 is not limited to one or more, so that the use of screws, due to the hardness of the material to produce a better application. The first feature of this creation 1 is shown in Figure 5. In order to overcome the influence of the chip ejection groove 19 and the retardation groove 18 on the screw's adhesion, the tolerance of the original screw thread base 14 diameter and the screw tooth mountain 15 outer diameter 'Canaanki The outer diameter of Asan 15 can be increased by more than 20%, which can solve the problem of using a wood screw c as shown in the third figure. Because the height difference η between the bottom of the tooth and Asan c4 is reduced, Influenced by the adhesion pull force or locking force, therefore, this creation has increased the adhesion pull force, but the outer diameter of the forging material is increased. Where does it increase the weight of the material so as not to increase the weight of the material, each screw and screw are widened? The distance between the teeth between the teeth, so that not only does not affect the tensile force of the screw during the pull-out test, and even increases the tensile force by at least 15%. In fact, without the above improvements, the tensile force of the screw will be reduced by less than 2% in the experiment. Far more than the market, the so-called wood screws, modified wood screws or other patented wood screws, the reason is that this creation is not the use of anti-tooth screw teeth broken into pieces or adding some cutting edges to the bottom of the screw teeth, both of which increase and Expand It aims to reduce the height of the screw thread and bottom teeth Asan and production of products, which not only can not completely overcome the crack on the lock on the timber dependents, but to reduce the burst and rift, even while locking tension and lack of more than ordinary wood screws. The second feature of this creation. Please refer to Figure 5. In order to increase the iron-like cutting and drilling ability, one or more drilling and milling wings 21 are set in the front section of the screw rod body 12, and its structure is as used in the market. The function of special drilling and milling cutters for steel. When drilling into wood by cutting into the hardwood by the inclined cutting edge 24 of the milling and milling wing 21, the hole diameter is enlarged by small and large 11 M273640: and the tension pressure generated by screw drilling is reduced , And until the cutting edge π reaches the optimal locking diameter of the screw, and the wood staggered vertical and horizontal fibers are cut by the cutting edge 25, the cut debris rises to the chip flute 19 through the incision 20, because the chip flute The design of 19 is penetrating, from the lower thread to the upper thread, so the wood debris gradually rises due to the pushing effect and is quickly discharged. The sloped cutting edge 24 and cutting blade 25 can strengthen all the cutting edges. The incision 20 is set in a concave or arc shape, that is, the incision 20 is lower, and the inclination cutter 24 and the cutting edge 25 are higher in order to make the cutting edge sharper and widen the incision 20 to make it more contiguous. Chip removal slot 19, to achieve faster chip removal, so In quality as hard as iron material it is easy. The third feature of this creation. Please refer to Figure 5. In order to achieve the function of spin-in, at the tapping point of steel and wood, when the screw rod body 12 rotates, the screw point 17 There are 1 or 2 guide screws 22, and the low point of the inclined cutting edge 24 on the drilling and milling wing 21 prompts the tool head to resist the work and the head and the screw rod body 12 head 1 when rotating this screw 〇 Connect the power, no lion with more pressure, the user can use almost only hands to carry out the construction, for the ceiling, external walls, fine standing points of poor environment, of course, it is easier to use, and avoid the Dangers from good health. In the experiment, the guide screw 22 may be set as a single screw or a double screw. The guide screw 22 is entered at the tip 23, and the low point of the slope cutter 24 on the guide screw slave iron milling wing 21 is extended (drilling and milling). The low point of the wing 'and adjusting the inclination angle of the guide screw 22 can make the guide screw 22 not only have a guiding effect, but also have the conditions for drilling into a thick iron plate. Ordinary wood screws ^ helmet method drills into the iron plate, even if it is barely Strengthen the sharpness of the screw teeth, the most young scale iron plate 12 M273640 has been difficult to achieve on average, but the results obtained in this experiment can penetrate through iron plates above 2 m / m, and the average penetration rate is above 98%. Improving the stability of the screw production material can be fully achieved. The fourth feature of this creation is shown in Figure 5. In order to achieve the functions of fast chip removal and sawing, the screw rod body 12 uses the head 10 to rotate the screw to generate a rotation action. At this time, the sawdust cut by the cutting edge 25 on the drilling and milling wing 21 will rise through the incision 20 to the screw tooth mountain 15. One or several penetrating types are arranged on the screw tooth mountain 15 and the through teeth are arranged from bottom to top Chip removal groove 19 on the mountain 15 and the bottom of the screw thread 14 The internal slow-groove groove Lu 18 has an expansion effect when the wood is screwed into the entrance of Luoya Yashan 15. Because the cutting angle 27 of Luoya Yashan 15 in the row of the groove 19 also has the function of cutting wood fibers, even the screw Because the tightening force of Yanyashan 15 has been increased by more than 20%, the expansion force is still reduced smoothly. As the screw rod body 12 is gradually drilled in, the sawdust cut by the cutting edge 25 continues to rise, and the screw tooth base 14 And the screw force of Asan 15 has gradually increased. Some fine wood chips have been squeezed into the density of the wood, and most of the wood chips have been smoothly discharged through the chip groove 19. In order to ease the chip groove 19 and the screw teeth The bottom 14 expands the tension of the unknown wood hardness and material, and slowly accumulates the space of the groove 18 to provide chip space to reduce the screwing torque of the screw and increase the spring force of the screw rod body 12 when screwing in. In the experiment 40m / m length, screws with an outer diameter of 4 · 5 or less, the chip removal groove 19 does not need to be deepened and widened, with a width of about 2.0m / m to the depth of the teeth, and the slow accumulation groove 18 is also within a width of 3.0 and a depth of 0. Within 5m / m you can achieve complete no cracks and cracks' relative length 50m / m or more, outer diameter 5 · 0 or more, it is necessary to deepen and widen the chip removal grooves 19 and slow accumulation grooves 18, even more than two or more chip discharge grooves 19 and 13 M273640 Slot 18 'talent _ does not chapped and cracked different preparation methods. [Second Embodiment] 19 can be obtained from Luoya Yashan 15 = dental office: mention [Third Embodiment] This creation of a screw improvement, as shown in Figure 8 As shown in the figure, the incision 20 can be penetrated into the drilling and milling portion 16 and the tooth tip 17 from top to bottom so that the low point of the inclined cutting edge% (drilling and milling wing low point 26) extends to the tip 23 of the tooth tip 17 at an inclination When the cutting edge 24 starts cutting wood, the guide screw 22 can simultaneously pull the screw into the wood. [Fourth Embodiment] An improved screw is created as shown in the ninth figure, in which the incision 20 can be penetrated into the drilling and milling portion 16 and the tooth tip 17 from top to bottom, so that the low point of the inclined cutting edge 24 (drill The low point of the sharp wing 26) extends to the tip end 23 of the tooth tip 17. The tooth tip 17 can be a two-stage inclination, such as a drilling and milling head 28 for drilling thick iron plates, which provides a better drilling and milling effect. [Fifth Embodiment] A screw modification is created as shown in the tenth figure, wherein the outer diameter of the drilling and milling portion 16 can be set smaller than the tooth bottom 14 so that the incision 20 extends from the tip 23 of the tooth inflammation 17 to the tooth bottom 14 (Drilling and milling wing 21 high point 29), the inclined cutting edge 24 of the milling and milling wing 21 extends to the tip 23, and the cutting edge 25 extends to the tooth bottom 14 (drilling and milling wing 21 high point 29), which can reduce the resistance to cutting wood .
