Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a screw, and more particularly to a expandable screw. [Previous Art] [0002] According to the conventional screw body, a screw body mainly includes a screw, and the screw has a thread, and one end of the screw forms a convex portion, and the convex portion is recessed with a cross or a groove of a straight shape. A screw driver is inserted to swivel the screw to facilitate the screw to tap into a screw. _ In use, the drilled hole of a suitable depth and bore diameter can be drilled with a drilled material, such as a plate of a decorative compartment, and then the screw of the conventional screw is screwed into the drilled hole. The biting force formed by the hole hole wall plate can screw the conventional screw to the plate, whereby the conventional screw can hang or support the article. However, the problem with the conventional screw is that if the inner material of the plate is relatively sparse, the biting force between the thread and the wall of the drill hole will be small, so that the screw is more likely to loosen even when the screw is used. When the load of the 0 load or the support is heavier, the conventional screw may even fall off. SUMMARY OF THE INVENTION [0003] In view of the previous problems, the inventors have finally obtained a configuration to improve the previous problems after many design and improvement. The invention relates to a expandable screw, which mainly comprises: a expanding member: comprising: a expanding tube: the inner tube wall is provided with a female thread, and the rear end portion of the expanding tube forms a plurality of petals. 099146128 Form No. A0101 Page 3 of 16 0992079312-0 201226726 A forced tube: the front end is operationally opposed to the rear end of the plurality of petals, and the inside of the resisting tube runs through a hole. a screw body includes a screw, the screw is provided with a male thread corresponding to the female thread of the expansion tube, and a rear portion of the screw is provided with a convex portion, and the convex portion is operatively opposed to the pressure tube The length of the screw is longer than the length of the pressure tube, and the outer diameter of the screw is slightly smaller than the diameter of the hole. Thereby, the screw is screwed into the expansion pipe and penetrates the expansion pipe, and the screw is tapped by the screw to gradually move the convex portion and the plurality of petals to gradually approach, so that the front end of the pressure tube resists the plural The valve body is forced to gradually expand the plurality of petals. And when the expandable screw of the present invention is to be screwed to a plate which is relatively sparse to an inner material (the plate may be composed of an intermediate layer between the two surface layers, and the material of the two surface layers is relatively hard, the material of the intermediate layer is The system is sparse. First, the plate is drilled with a hole of appropriate depth and inner diameter, and then the expansion tube and the pressure tube are sequentially inserted into the hole, and then the screw of the screw body is worn. Extending the hole, and rotating the screw to screw the screw with the expansion tube, and then continuously rotating the screw to cause the screw to tap forward to sway the protrusion and the plurality of petals gradually approaching The front end of the compression tube resists the plurality of petals to force the plurality of petals to gradually expand. When the plurality of petals are diverging, the plurality of petals form an expansion portion, and the expansion portion can be offset against one side of the surface layer by the continuous screwing of the screw to provide a fastening force, thereby enabling the present invention The expandable screw and the screw of the plate are stronger and less prone to loosening or falling off, so that the conventional screw of the plate can be solved because the inner material of the plate is sparse, and the thread formed by the thread and the hole of the drill hole is compared. Small, and easy to loosen or fall off the conventional screw; and the gradual expansion of the plurality of petals can also increase 099146128 Form No. A0101 Page 4 / Total 16 Page 0992079312-0 201226726 The expansion tube and _ hole (4) When the rotating force material and the expansion tube are screwed together, the idling is less likely to occur. However, based on the generalized and invented concept, the present invention provides a single-request item for the aforementioned expandable screw material; and the standard member can be applied to different types of screw bodies, and is not limited to the drawings of the present specification. Revealed. [Embodiment] [0004] The structure, the content, and the embodiments of the present invention are explained in the following by means of the accompanying drawings, and the review of the present invention will be further understood. Referring to the first aspect, as shown in the fourth figure, the expandable screw of the present invention mainly comprises: / · a expansion member (A): a expansion tube (1): the inner tube wall is provided with a female thread (11) And the rear end portion of the expansion tube (1) forms a plurality of petals (12). An escaping tube (2): the front end operability is opposite to the plural number; the _ body (12) rear end, and the inner side of the espressing tube (2) runs through a hole (21). a screw body (3): comprising a screw (31), the screw (31) is provided with a male thread (311) corresponding to the female thread (11) of the expansion tube (1), and the screw (31) a rear portion is provided with a convex portion (312) operatively opposite to the rear end of the resisting tube (2), the length of the screw (31) being longer than the length of the resisting tube (2). The outer diameter of the screw (31) is slightly smaller than the diameter of the bore (21). Thereby, the screw (31) penetrates the tunnel (21) and is screwed with the expansion tube (1), and the screw (31) is used to sway the protrusion (312) and the plurality of petals. The body (12) is gradually approached so that the pressure tube (2) front form number A0101 page 5/16 pages 0992079312-0 201226726 end forces the plurality of petals (12) to force the plurality of petals (12) ) Gradually expanding. And when the expandable screw of the present invention is to be screwed to a plate (4) which is sparse to an inner material [refer to the fourth figure, the plate (4) is provided with an intermediate layer between the two skin layers (41). (42) is composed of, and the material of the two skin layers (41) is relatively hard, and the material of the intermediate layer (42) is relatively sparse] firstly drilling the plate (4) with a hole of appropriate depth and inner diameter (43), and then sequentially inserting the expansion tube (1) and the pressure tube (2) into the drill hole (43), and then threading the screw (31) of the screw body (3) into the hole (21), and rotating the screw body (3) to screw the screw (31) with the expansion tube (1), and then continuously rotating the screw body (3) to screw the screw (31) forward To sway the protrusion (312) and the plurality of petals (12) to gradually approach the front end of the compression tube (2) to force the plurality of petals (12) to force the plurality of petals (12) Gradually expand. When the plurality of petals (12) are gradually expanded, a expansion portion (123) is formed, and the expansion portion (123) can be offset from one side of the surface layer (41) by the continuous screwing of the screw (31). In order to provide a fastening force, so that the expandable screw of the present invention and the screw of the plate (4) are more rigid and less prone to loosening or falling off; and the plurality of petals (12> can also be added when expanding The friction between the expansion tube (1) and the hole wall of the bore (43) is such that the screw body (3) and the expansion tube (1) are less likely to be idling when screwed. However, the present invention is applicable. The screwed object is not limited to the plate material (4) shown in the fourth figure, but may also be the plate material (5) shown in the fifth figure or other aspects (not shown), as disclosed in the fifth figure. The thickness of the plate (5) is such that the expansion portion (123) abuts against one side of the plate (5) to provide a -buting force: 099146128 岙% 赝 I have the same inventive concept, the present invention is the aforementioned expandable screw The expansion piece (A) (as shown in the second figure), the other provides - bite /, flat one δ month request.
