[0026] In this embodiment, after the steel bar body 3 enters the interior of the first sleeve 1 and the second sleeve 2, it squeezes multiple arc-shaped clamps 5, causing them to deform and form an outer diameter that matches the steel bar body 3. The external hexagonal locking nut 8 is threadedly connected to the external threaded part 6 of the multiple arc-shaped clamps 5, and the internal anti-slip part 7 is tightly fitted to the steel bar body 3, thereby locking the steel bar body 3 and improving friction and connection stability, so that the two steel bar bodies 3 are connected to the first sleeve 1 and the second sleeve 2 respectively.

[0027] Example 2

[0028] like Figures 1-4 As shown, the first sleeve 1 has a threaded groove 9 on its outer side, which mates with the internal thread 10 to form a threaded connection between the first sleeve 1 and the second sleeve 2. The second sleeve 2 has an internal thread 10 on its outer side that mates with the threaded groove 9. The second sleeve 2 has multiple arc-shaped grooves 11 equidistantly spaced on its inner side. These arc-shaped grooves 11 are equidistantly spaced on the outer side of the second sleeve 2, which not only enhances the aesthetics but also facilitates the use of external tools to rotate and tighten them. The inner diameters of the insertion holes 4 inside the first sleeve 1 and the second sleeve 2 are the same. There are deformation gaps between the multiple external threaded portions 6 inside the first sleeve 1 and the second sleeve 2, and they are inclined inwards.

[0029] In this embodiment, the threaded groove 9 on the outside of the first sleeve 1 engages with the internal thread 10 on the outside of the second sleeve 2, thereby enabling the first sleeve 1 and the second sleeve 2 to drive the internal steel bar bodies 3 to connect, improving connection efficiency and connection strength. By setting the arc-shaped clamp 5 and the external hexagonal locking nut 8 inside the first sleeve 1 and the second sleeve 2, the aesthetics of the external connection are improved.

After the steel bar bodies 3 enter the interior of the first sleeve 1 and the second sleeve 2, they are squeezed by multiple arc-shaped clamps 5, causing them to deform and form an outer diameter that matches the steel bar bodies 3. The external hexagonal locking nut 8 is threaded to the external threaded part 6 of the multiple arc-shaped clamps 5, and the internal anti-slip part 7 is tightly fitted to the steel bar bodies 3, thereby locking the steel bar bodies 3 and improving the friction and connection stability, so that the two steel bar bodies 3 are connected to the first sleeve 1 and the second sleeve 2, respectively.

[0031] Then, the threaded groove 9 on the outside of the first sleeve 1 is engaged with the internal thread 10 on the outside of the second sleeve 2, thereby enabling the first sleeve 1 and the second sleeve 2 to drive the steel bar bodies 3 inside them to connect, thereby improving the connection efficiency and connection strength.

[0032] By setting the arc-shaped clamping plate 5 and the hexagonal lock nut 8 inside the first sleeve 1 and the second sleeve 2, the appearance of the external connection is improved, and the arc-shaped groove 11 can cooperate with the external tool to rotate the second sleeve 2, improving the practicability.
