V. Description of creation (3) Make the reviewing committee understand clearly that the creator of the creation will cooperate with the following drawings and understand the spirit of the creation: [Detailed description] As shown in the first and second pictures, this is the main picture. It consists of a main body 1 and a 'the main body 1 is cylindrical, the end is to the right) increasing tapered end 11 and the other set 2 is cylindrical, the set is placed in a spiral winding and has an elastic expansion direction 'In order to facilitate the locking effect that can be expanded and wrapped when used, the nut 3 is provided with one end provided with an external thread 12. As shown in the third figure, in order to use the original cross-sectional view, because the kit 2 has a spring-like 'when the nut 3 is tightened, there is a gap', so the body 1 is also close together first. Axial moving ring 2 1 The cone along the main body 1 cone end 1 1 has elasticity, so it covers the inner wall of the hole outside the cone end outside the wall, greatly increasing the detailed process and technical content of the contact surface. This detailed explanation In order to make sure that the reviewing committee clearly created the plan of the gecko nail and the disassembly kit 2 and a nut 3, the components are constructed from the inside to the outside (as shown in the figure, there is an external thread 1 2 from the left end periphery, and the middle part of the body 1 , The end is provided with a ring 2 1, the position is the same as the cone end 1 1 on the periphery of the cone end 1 1 to achieve an excellent internal thread 3 1, then the gecko nail that can be screwed to the main body is placed in the hole in the wall so that The expansion ring 21 is spirally wound and the expansion ring 21 is spirally formed. At this time, as the nut 3 is continuously rotated (toward the nut), the expansion face will be forced to expand outward, because it is spirally wound. And the way of the garden expands, finally close to the top stop, the relative friction is also increased, and through M267361 _ No. 91211908_ year and month correction_ V. Creation Instructions (4) The expansion ring 2 1 exerts a positive radial pressure on the wall of the cave, and the effect of adding and multiplying the two also greatly improves the locking effect. In addition, the kit 2 The outer circumference of the expansion ring 21 is not a completely smooth surface. In fact, the outer surface of the expansion ring 21 can be formed by rough processing, such as embossing, scratching, troweling, or sanding into a rough surface. The rough surface can increase the friction with the inner wall of the wall hole during locking, making it more difficult to loosen or separate. In addition, as shown in the first and second pictures, it can also be at the end of the cone 1 of the main body 1 Add a pressing section 1 3. The taper here is different from the taper of the taper end 1 1.

In this implementation, the taper is 0, that is, the pressing section 13 is cylindrical. When the expansion ring 21 is expanded there, it is the maximum outer diameter and it is more difficult to turn the nut 3, so the pressing can also be made. Segment 13 was changed to a tapered surface with a gentler taper to continue to increase the contact area of the expansion ring 21 with the wall surface and increase the firmness. Therefore, the taper end can be a single taper taper surface, multiple taper taper surfaces with different tapers, or a tapered surface with an arc curve. This embodiment can be useful to other embodiments herein.

The fourth figure is a diagram of the second embodiment of the creation. In this embodiment, the shape of the end of the main body 1 is mainly changed. As shown in the figure, the end of the main body 1 is still provided with a tapered end 1 1, but the tapered end 1 1 is the largest outside. There is a pressing section 1 3 at the end of the diameter, and a larger stopper 14 is provided at the end of the pressing section 13. However, the maximum outer diameter of the stopper 14 needs to be smaller than the outer diameter of the kit 2 to avoid obstructing the gecko nail. It is placed in a hole in the wall. The main purpose of the stopper 14 is to prevent the expansion ring 2 1 of the kit 2 from moving too large and exceeding the entire length of the tapered end 1 1. The other purpose is to increase the overall strength and make it more useful in use. for safety.
