[0002] According to the general indoors, there are hanging hooks or other items that need to be fixed on the wall, and most of them are fixed by hanging screws or objects. As shown in Fig. 1A, a conventional screw 1 includes a nail head 11, a nail body 12, and a plurality of threads 13, which are disposed on the surface of the nail body 12. Wherein, the screw 1 is below the nail head 11, and the shape of the nail body 12 and the angle formed by the thread 13 generally exhibit a uniform structure. [0003] As shown in FIG. 1B, it is an example of a screw 1 and a gecko 2 application. The application process of the screw 1 and the gecko 2 is as follows: First, a hole 直径 having a diameter and a depth equal to the size of the gecko 2 is drilled on the wall. Next, the gecko 2 is hammered into the above hole. Then, the screw 1 is rotationally locked by the opening 0 of the head 21 of the gecko 2. At the same time, the hanging hook or the object can be fixed to the wall while being screwed into the gecko 2 by the screw 1. Among them, the screw 1 is shown in the direction of FIG. 1Β, and is rotated into the gecko 2 by the outside of the wall according to the direction A to the inside of the wall, so that the nail body 12 and the thread 13 of the screw 1 gradually move toward the gecko 2 from the inside of the gecko 2 The outer side is squeezed, so that the gecko 2 gradually presses the wall, so that the screw 1 and the gecko 2 can be firmly fixed to the hole of the wall. [0004] However, when the screw 1 is gradually rotated into the gecko 2 from the outside of the wall, the shape of the screw 1 and the angle formed by the thread 13 have a uniform structure, so that the meshing force of the thread 13 locked into the inner wall of the gecko 2 is relatively better.

In other embodiments, the cross-sectional shapes of the first threads 311, the second threads 321 and the third threads 331 may be tapered, respectively, or circular, or respectively tapered or round. Any combination of shapes or other shapes may be the same or different from the side flank angle and the side flank angle, and is not limited thereto. 1013048579-0 Page 9 of 24 M426674 [0031] 101 years Ό February 0 9 - The replacement page is particularly emphasized in other implementations, the first thread 311, the first The two threads 321 or the third threads 331 can respectively have different combinations of the angles of the pull-out side and the side angle of the screw. The present invention does not specifically limit the pull-out of the side and the side of the screw. The angle of the angle and its combination, the change of the soffit angle of the pull-out side and the angle of the screw into the side of the screw and the combined aspect are not beyond the creation.

[0032] Hereinafter, please refer to FIG. 4A to FIG. 4C to illustrate the state in which the screw 3 of the present invention is used in conjunction with a wall tiger 4. Among them, the gecko 4 may have a top portion 41, and the screw nail 3 is rotatably locked into the interior of the gecko 4 by the opening 01 of the top portion 41. [0033] In the present embodiment, one side surface S5 of the gecko 4 may have a plurality of bumps 42 and a plurality of through holes 43. Wherein, the protrusions 42 are arranged such that when the screws 3 are locked into the interior of the gecko 4 and the gecko 4 is forced to the outer wall, the gecko 4 and the wall can have a large friction force, so that the gecko 4 and the lock wire The lamp 3 can be more securely attached to the wall. [0034] Therefore, as shown in FIG. 4B and FIG. 4C, when the screw 3 is rotationally locked from the outside to the gecko 4, the design of the different diameters of the nail body at different stages of the screw 3 can form different stages for the gecko 4 The force of outward expansion makes the rotation of the screw 3, 311, 331 of the screw 3 to the inner wall of the gecko 4 less than the lock of the conventional screw, so the screw 3 of the present invention is easier. The advantage of rotary locking. In addition, because the screw 3 of the present invention has different rod diameters, and the different rod diameters cause the thread 311 of the first nail body 31 of the screw 3 to lock into the gecko 4, the gecko 4 is stretched outward and pressed tightly. When the strength of the wall is small, and then the second nail body 32 and the third needle body 33 of the larger diameter are locked, the threads 321 and 331 of the second nail 1013048579-0 body 32 and the third nail body 33 can be Gecko 4's bite strength 10022090 Strictly numbered A01〇l Page 10 of 24 M426674 101. On February 09, the nuclear replacement page and the gecko 4 are forced to the wall to make the screw 3 connect to the wall. stable. [0035] In summary, the second diameter of the second nail body of the screw is larger than the first diameter of the first nail body, and the third diameter of the third nail body is greater than the second diameter of the second nail body. When the screw of the creation is locked into a gecko, a wooden board, a wall or the like, the different diameters of the first nail body, the second nail body and the third nail body can be used to form different stages of the object outward. The force of expansion makes the rotation of the screw at the same time as the threading force of the screw on the inner wall of the object is not as much as that of the conventional screw with the same rod diameter. Therefore, the screw of the present invention has the advantage of being easy to rotate and lock. In addition, because the screw of the present invention has different rod diameters, when the first nail body of the smaller rod diameter is locked into the object, the object is stretched outward by the thread of the first nail body and is forced to the wall. When the second nail body and the third nail body of the second nail body and the third nail body are locked, the force of tightening the thread of the second nail body and the third nail body and the object is increased, so that the screw is connected to the object. stable. Therefore, the screw of the present invention has the advantage that it is easy to rotate and lock, and the connection is relatively stable.
