Recycling and recycling of wastes such as environmentally-friendly recycled composite materials, such as the United States and Canada, have already smashed poems or (4) and wood W, and then extruded them under high-temperature pan-pressure to form a slightly elastic and environmentally-friendly recycled composite material. The situation that we can use wood in the current. However, it is environmentally friendly when it is screw-locked: When the P material is smashed, the composite material does not have the intertwined structure of the wood-specific fibers, and in the process of screwing in the screw, the temple will produce the scoop. The swarf pushes up and pushes up the bulge of the bulge on the surface where the screw is screwed in and a lot of residual debris. Even when the screw hole is close to the edge of the composite material, cracks are generated, which greatly affects the overall appearance and structural safety. Although the current industry has sought solutions to this phenomenon, there are still several shortcomings, as explained below. As shown in FIG. 1 , the conventional screw 丨 includes a screw head and a screw 12 , which is composed of a reaming section 13 , an edentulous section 14 , and a spiral fin (3) having a thread outer diameter d and a 1227545 screw bottom diameter e, and a reaming spiral fin (3), each of which has a spiral direction opposite to the thread H of the thread H, ^ Again spiral direction. Since the outer diameter of the spiral fins 131 is larger than. The outer diameter d of the thread of the snail tooth segment 15 is limited, and the space for reaming is limited, and the hole segment 13 is not close to the thread segment & but is separated by a distance of the length of the segment 14), and therefore, The environmentally-friendly recycling of the unwinding: the space of the early debris is only the space above the reaming section 13, and it is still easy to release the composite material and the squeezing of the composite material so that the surface after the locking is screwed into the hole if it is close to the composite A crack occurs at the edge of the material, and it is known that the second screw 2 includes a screw head 21 and a screw 22, the screw f segment 23, the toothless segment 24, and the second screw. Teeth..., 'Chengkou Haidi I,-worm? 5F f Where 9. n r· — Threading slaves 23, 25 can be defined as - first, second gl, g2 and a first and second screw pitch μ. Wherein, the pitch M 1 gl is Θ in the outer diameter of the second thread, and the spiral direction of the first thread is the same in the second thread pitch h2'. '宇才奴23: From the 5 Haidi-nail section 23 screwed into the environmentally-recyclable composite material, the tooth segment 25 is one of the debris of the first screw segment 23, and accommodates the toothless segment % With the hole wall formed after the ^ work. In terms of volume, if the entire screw 2 is locked into the environmentally-friendly recycled composite material, the crumb-shaped nucleus space will not be able to accommodate all the large-scale and insufficient swells (4) the ridge of the composite material during the environmental protection, 1227555 and debris. After the lock, the surface of the hole has a bulge and a phenomenon. : It is easy to generate cracks when the composite material is screwed into the hole in the environment and close to the edge of the composite material. Therefore, the screw of the present invention for environmentally-recyclable composite material can form a space for accommodation. 2 and 4 can maintain the environmentally friendly composite composite locking surface =: The right is close to the edge of the composite without cracks, maintaining the beauty and structure of the female gold. : The present invention is used for the insured recycled composite material in a composite material of plastic or plastic gentleman's t-perimeter lock wood chip, the insect wire comprises a screw of:::... .

M. The head 3 can define a screw outer diameter a and form a slot for the tool to be inserted. The recess 31 can be a conventional cross, a quadrangle, a hexagonal opening: a mellow shape, a m shape Or a variety of seven-shaped 'phase slot holes 31 (four) shape, such as the multi-dimensional polygonal shape of Fig. 3, is not an important feature of the present invention, and the deer is used to limit the scope of patent application of the present invention. The squeezing cup 4 includes a rod body 41, and the body two-way screw segments 42 spaced apart from the rod body 41 are correspondingly disposed on the rod body 41 and corresponding to the reverse thread segments 43 and Wings between the cymbal 44 δ 正向 forward screw segment 42 and the reverse screw segment 43. Further, at the end of the side shank 41 and connecting one end of the forward screw segment 42, the spur is less itR Λ σ . The fins 44 are adjacent to the forward thread segments 42 and may also abut the forward thread segments 42. The yoke forward screw segment 42 is adjacent to the end of the shank 41 and defines a snail 8 1257455 tooth outer diameter b.

Between the outer diameter of the thread of the forward screw segment 42 and the outer diameter a of the screw head of the head 3, in the present embodiment, the screw * includes two and two wings of the opposite side of the rod body 41. The thorn tip can position the _ wire on the environmentally-friendly recycled composite material, into the environmentally-friendly recycled composite material. The material is rotated against the positive screw segments as shown in Figures 4 and 5 'recovering the composite material by the thorn tip of the screw 4' and guiding the forward screw segment 42 to be recycled in the environmentally friendly recycled material. . Continue to screw in the forward screw of the screw & 42, because the forward screw segment 42 will be circumvented after the environmental protection of the composite material and produce residual ^, so that the composite material is formed on the surface of the rotating hole — The bulge 5 and the debris 7. Then, when the fins 44 begin to enter the environmentally-friendly recycled composite material, each of the fins 44 will rotate the environmentally-friendly recycled composite material, and the screwed holes are enlarged to form a accommodating debris 7. Space 6. When the reverse screw segment 43 begins to enter the accommodating space, at 6 o'clock, the environmentally-recoverable composite material scraps 7 cut by the forward screw segment 42 and the fins can be pressed into the accommodating portion. In the space 6, the formed humps 5 are pre-pressed into the accommodating space 6 by the screw head 3, so that the surface of the eco-recyclable composite material table 1227555 can be kept flat. Since the fins 44 are adjacent to the forward screw segments 42, the accommodating space 6 formed has sufficient space for accommodating the composite of the forward screw segments 42 and the fins. The material 剌7, = does not occur, the composite scraps 7 that are accommodated are squeezed against each other due to insufficient space, resulting in a convexity on the surface of the composite material or a crack near the edge of the composite material. m
