Description of the invention: [Technical field to which the invention pertains] An expansion screw, in particular an expansion screw which produces at least three stages of the effect of folding and buckling, by which the tensile force of the expansion screw is supported, and the resulting material is folded and supported. Strength, to prevent construction from being unscrupulously caused by excessive pressure on the working hole. [Prior Art] According to the general use of the wall (such as gypsum wallboard, etc.) to provide the object to hang the expansion screw 1 (as shown in the first and second figures), which is mainly in the action area 11 of a nail seat 10 The upper distribution is provided with a plurality of longitudinal long holes 12 and a plurality of long strips 13. The central portion of the long strips 13 is slightly convex outward, and the upper and lower sides thereof are respectively retracted obliquely toward the side ends to form an upper segment 131. And the segment 1 3 2, and the pulling force P of a bolt 14 is acted upon by the pulling tool f, so that the action i produces an outward expansion deformation, and the nail seat 1Q is mosquito-mattered! After the construction, the situation should be as shown in the second figure; but in fact, the long strip i 3 is not so smooth in the process of expansion and deformation, and the bad fixation result as shown in the third figure often occurs. The reason is that the strip 13 has only two-piece pieces, that is, the upper part 131 and the lower part 13 2 cannot fully achieve the folding and topping effect, and sometimes the upper part is 丨3丨 and the lower part. Duan 丨 3 2 will produce a parallel situation, resulting in the upper section i3i can not clamp the wall W1 ^ 'causing the phenomenon of fixed fixation; even more will produce a squeeze point excessive H working hole B 1 at the edge of the hole After the expansion of the skin 1 1 occurs (as shown in the second figure), especially when the thickness of the wall W2 is thin (as shown in the figure), the leg 1 1 of the expansion screw will expand. Inserted into the wall W2, causing damage to the surface of the wall W2; so the industry 1289632 expansion screw 2 (such as the United States 4,986, : it mainly consists of a nail seat 2 0 and - bolt 2 1 upper jaw: segment is - active area 203, This is made up of a 20-length strip of 2 0 4, but this change

The second segment 315 is located on the lower side of the second segment 313 and is connected to the second segment 3 1 3 and forms a larger than 9 2 ′ and extends downward to the head end 3 of the needle holder 3Q. The end edge 3 3 2 ' of 3 forms a support for the completion of the first segment 3 after expansion. The composition of the above structure, when the expansion screw 3 penetrates into the wall boundary 4, 隹 (as shown in the twelfth figure), with the tension tool F on the bolt 3 seat? Because the position of the action zone 31 is the whole nail = ΐΐ At the part, the expansion deformation will occur outward, and the distance s long = the cause of the "guide 4 force": the area where the loyalty is weakened, so it will become - turn: ΐ first and second press lines 312, 314 The shape 11 is the most τιΐ traction toward the nail seat 3 2, the first segment 3 is pulled by the surface of the wall w, then the second segment 313 311, the shape is used, and the fold is forced to fit on the The first segment is in a material overlapping state, and the third segment 3 1 5 9 1289632 is forwarded to 'but since the length of the third segment 315 is much larger than the second segment 3 1 $, the third segment is made The 315 forms a support angle 0 3 with the first segment 311, and constitutes a top abutting support structure, so that the first segment 311 is in close contact with the surface of the wall w, and the second segment 313 is folded and adhered to The first segment 311, together with the top portion of the third segment 3丄5, forms at least three segments of folding and supporting effects, so that no sturdy and unstable conditions occur, and The pressing point is evenly distributed on the area where the first segment 31 is in contact with the surface of the wall W (instead of a local point); therefore, excessive stress is not concentrated near the edge of the working hole B to ensure construction. According to the thirteenth embodiment, when the thickness of the wall boundary 5 is thin, the first segment 311 is expanded, and the front side 3 is completed with the guiding force. The turning is suspended, and the rear side 31 11 is still maintained close to the surface of the wall W5, so that the situation of the folding of the wall surface after expansion is not caused, so as to ensure the folding fastening and supporting effect. In the invention, the second section 313 and the third section 315 are respectively provided with a reinforcing rib 3131, 3151, thereby strengthening the strength thereof, and ensuring that the turning point can be concentrated on the first and second pressing lines 312, ] 14 . The structure of the second segment of the invention can be implemented in the following manner, as in the embodiment shown in Fig. 14, wherein the long strip 3 i 〇, the first knife blade and the upper and lower ends of the 313 are On both sides of the first and second press lines 3 1 2', 3 1 4', respectively a notch Al, A ^ ' is used to weaken the second segment 3 1 3, the upper and lower ends (ie, the first 'two press lines 3 1 2, 3 1 4), to concentrate the stress on this The second segment 3 1 3 can be smoothly turned. Further, as in the embodiment shown in the fifteenth figure, wherein the long segment 3 1 〇" is on the second segment 3 1 3" The lower ends, that is, the inner sides of the first and first press lines 3 1 2" and 3 1 4" are respectively provided with two lateral grooves C1, c2, thereby weakening the upper and lower ends of the second segment 313" (ie, the first and second press lines 3 12", 3 14") to guide the stress concentration to make the second segment 313" turn. In summary, the present invention can improve the construction yield, and by the first, the segmentation, after the expansion, due to the overlap of the materials, with the support of the third segment, the multiple support of the formula The effect is effective to prevent the lack of hole in the working hole and the excessive pressure of the working hole, and it is particularly practical and effective.
