[0009] According to the stainless steel threaded nail fastener of this utility model, the positioning block has an internal receiving groove, and the end of the first matching block is located inside the receiving groove. There are two of each of the first and second matching blocks, symmetrically distributed on both sides of the first threaded post. The first and second matching blocks fold and support each other under the action of the limiting block, thereby increasing the contact area and strengthening the stability of the overall connection.

[0010] According to the stainless steel threaded nail fastener of this utility model, both the top head and the end connector are provided with recessed slots, which are cross-shaped. The cross design of the recessed slots can be used with standard Phillips screwdrivers or special power tools, improving installation efficiency.

[0011] According to the stainless steel threaded nail fastener of this utility model, a buffer pad is fixedly connected to the upper surface of the positioning block. The buffer pad is located outside the first threaded post, and the end joint of the first threaded post abuts against the overlapping block during use. Through the elastic deformation of the pad, the concentrated stress at the end of the threaded post is evenly transferred to the overlapping block, avoiding excessive local stress.

[0012] Beneficial effects: Compared with the existing technology, this new type of stainless steel threaded nail fastener uses the end joint to squeeze and push the overlapping block, and cooperates with the side rod and movable block for limiting support. This allows the first and second matching blocks to form a fastening structure with an adjustable support range under the action of the limiting block. It can not only strengthen the connected parts, but also adapt to the installation requirements of different sizes. In addition, when needed, the fastening tip of the second threaded post can be taken out from the inside and used as a guide drill bit. Attached Figure Description

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0021] Reference Figure 1-4 The present invention relates to a stainless steel threaded nail fastener, comprising: a top fixing head 1, a receiving body 2 fixedly connected to the lower surface of the top fixing head 1, a first threaded post 3 fixedly connected to the side of the receiving body 2 away from the top fixing head 1, a positioning block 4 threadedly connected to the outside of the first threaded post 3, a first matching block 5 rotatably connected to the bottom of the positioning block 4, a limiting block 16 rotatably connected to the bottom of the first matching block 5, a lateral rod 17 rotatably connected to the side surface of the limiting block 16, a movable block 18 rotatably connected to the end of the lateral rod 17, a fixed post 19 slidably connected inside the movable block 18, a fixed post 19 fixedly connected to the outside of the fixed post 19 and the first threaded post 3, a second matching block 6 rotatably connected to the lower surface of the limiting block 16, an overlapping block 7 rotatably connected to the end of the second matching block 6 away from the first matching block 5, and a second threaded post 8 threadedly connected inside the first threaded post 3.

[0022] Specifically, the end connector 11 drives the second threaded post 8 to rotate, so that the end connector 11 can squeeze the overlapping block 7, thereby causing the overlapping block 7 to drive the second matching block 6, the limiting block 16 and the first matching block 5 to adjust, thereby increasing the contact area of ​​the fastener. In conjunction with the movement of the movable block 18, the lateral support angle of the lateral rod 17 is adjusted, thereby making the overall support structure more stable.

[0023] A spring 9 is fixedly connected to the lower surface of the top head 1, and a rubber pad 10 is fixedly connected to the bottom end of the spring 9. The inside of the rubber pad 10 is slidably connected to the first threaded post 3. A buffer pad 15 is fixedly connected to the upper surface of the positioning block 4. The buffer pad 15 is located outside the first threaded post 3. The end joint 11 of the first threaded post 3 abuts against the overlapping block 7 during use.

[0024] Specifically, the spring 9 and the rubber gasket 10 combine to form a dual buffer system, which can absorb the impact load transmitted by the top head 1, while providing continuous preload through the deformation of the rubber. The radial wrapping design of the buffer gasket 15 can suppress the lateral vibration of the first threaded post 3, improving dynamic stability.

[0025] The inner sliding connection of the overlapping block 7 is a second threaded post 8, the end of the second threaded post 8 is fixedly connected to an end connector 11, and the end of the second threaded post 8 away from the end connector 11 is fixedly connected to a fastening tip 12. The interior of the first threaded post 3 is a hollow threaded structure. When not in use, the fastening tip 12 of the second threaded post 8 is located inside the first threaded post 3. The radius of the first threaded post 3 is larger than the radius of the second threaded post 8.

[0026] Specifically, the overlapping block 7 can be moved by the end connector 11 of the second threaded post 8, thereby allowing the support mechanism to be adjusted. Furthermore, the hollow structure of the first threaded post 3 provides storage space for the second threaded post 8, keeping the fastening tip 12 hidden and protected when not in operation.

[0027] The positioning block 4 has a receiving groove 13 inside. The end of the first positioning block 5 is located inside the receiving groove 13. There are two of each of the first positioning block 5 and the second positioning block 6, which are symmetrically distributed on both sides of the first threaded column 3. The top fixing head 1 and the end connector 11 are both provided with a hole groove 14 inside. The hole groove 14 is cross-shaped.

[0028] Specifically, the cross structure of the recessed groove 14 enhances the tool engagement stability and facilitates tool insertion, thereby adjusting the rotation of the top fixing head 1 or the end connector 11.

[0029] Working principle: First, the first threaded post 3 is passed through the connector to be fixed. Then, the positioning block 4 is rotated to move it outside the first threaded post 3 and move the positioning block 4 to a fixed position. Then, the second threaded post 8 is rotated through the end connector 11, so that the end connector 11 can squeeze the overlapping block 7. This causes the overlapping block 7 to adjust the second matching block 6, the limiting block 16 and the first matching block 5, thereby increasing the contact area of ​​the fastener and improving the overall fastening effect of the structure.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
