[0028] A cover plate 3, which is installed above the base and is provided with a circular hole for the fastening nail to pass through;

[0029] A limit wire 4, which is an arc-shaped elastic member, is arranged in an arc-shaped groove on the upper part of the base, and can be deformed in the arc-shaped groove, and the arc-shaped groove can prevent the limit wire from loosening;

[0030] A second connected member 6, the cover plate 3 and the base 2 are mounted on the back of the second connected member 6, a recessed portion is provided on the second connected member 6, and a through hole is formed at the bottom of the recessed portion;

[0031] A first connected member 5, wherein a protrusion matching with a recessed portion of a second connected member 6 is provided at the bottom of the first connected member 5, a threaded hole matching with an upper external thread of the fastening nail is provided at the bottom of the protrusion, and the fastening nail 1 is fixed to the bottom of the first connected member through the upper external thread;

[0032] After the lower end of the fastening pin passes through the circular hole of the cover plate, it is inserted into the cavity of the base. The large head end of the conical structure at the lower end of the fastening pin passes over the limiting steel wire during the elastic deformation of the limiting steel wire by squeezing it, and the limiting steel wire is stuck in the recessed part of the fastening pin, thereby fastening the fastening pin and completing the connection between the first connected part 5 and the second connected part 6.

[0033] See also Figure 2The fastening nail shown is manufactured by machining, and the material selected is stainless steel, which has high strength and good corrosion resistance and meets the use requirements. The lower end is designed to be a conical structure 11, which has good guiding ability. During the fastening process, it can smoothly remove the obstruction of the limiting steel wire and snap into the structure. The middle part of the part is narrowed to form a concave neck 12, which is used to accommodate the limiting steel wire, form a fastening force, and prevent the fastening nail from falling out of the connection part. The upper part of the part is designed to be an external thread 13, which can be screwed into the connected part. In order to improve the assembly process of the part, a square structure 14 is designed in the middle of the part, which is convenient for tightening the part with tools such as wrenches.

[0034] See also Figure 3 The cover plate 3 shown is manufactured by machining, and the material is stainless steel, and the surface of the part is polished. A large circular hole 31 is designed in the center of the part, which is the passage for the fastening nail to pass through; the lower surface of the part is designed to be flat, which is used to provide reliable constraints to the limit wire to prevent the limit wire from moving beyond expectations. Two countersunk holes 32 and two through holes 33 are designed on both sides of the part, wherein the countersunk hole 32 is used to use two countersunk screws to reliably fix the cover plate on the base, and the two through holes 33 are used to pass the mounting screws of the entire assembly.

[0035] See also Figure 4 The limit wire 4 shown is manufactured by machining and is made of stainless steel wire. The part is designed to be arc-shaped, and its shape is conformal to the groove of the base, so that it can be stably embedded in the groove when installed in the base. When the fastening nail is buckled in, the limit wire is squeezed by the guide cone and deformed; when the fastening nail is buckled in, the limit wire elastically recovers and clamps the fastening nail, so that the fastening nail is reliably buckled.

[0036] See also Figure 5 The base 2 shown is manufactured by machining, and the material is stainless steel, and the surface of the parts is polished. A cavity 21 for accommodating the fastening nail is provided in the base, and a half-moon-shaped groove 22 connected to the cavity 21 is designed on the upper surface of the base to accommodate the limit wire. Even if the limit wire is deformed, the groove can still provide reliable constraints. Threaded holes are designed at both ends of the base, of which two M2.5 threaded holes are used to fix the cover plate on the base, and two M3 threaded holes are used to install the entire assembly on the connected part.
