[0021] By providing the limiting plate 11, when the first steel bar 2 abuts against one side of the limiting plate 11, the first steel bar 2 is limited, so that it is not necessary to repeatedly calibrate when the subsequent bolt 6 abuts.

[0022] Furthermore, a through hole 8 is provided on the inner wall of the first steel bar 2, and the surface of the second steel bar 9 is inserted into the first steel bar 2 through the through hole 8.

[0023] By providing the through hole 8, it is convenient for the first steel bar 2 to be inserted into the second steel bar 9.

[0024] Furthermore, a first anti-slip pattern is fixedly connected to the surface of the first nut 4, and one side of the limiting plate 11 abuts against the surface of the first steel bar 2.

[0025] By providing the first nut 4, when the first nut 4 abuts against the surface of the first steel bar 2, the connection between the first steel bar 2 and the second steel bar 9 is realized.

[0026] Furthermore, one side of the first nut 4 abuts against the surface of the second steel bar 9.

[0027] Furthermore, a second nut 7 is threadedly connected to the surface of the bolt 6, and the right surface of the second nut 7 abuts against the left surface of the first steel bar 2.

Then, control the second nut 7 to rotate clockwise on the bolt 6 until it abuts against the surface of the first steel bar 2. At the same time, control the first nut 4 to rotate on the first steel bar 2 and move towards the second steel bar 9 until it abuts against the surface of the second steel bar 9. At this time, it is convenient for concrete pouring. This device is convenient and fast to assemble and has high stability.
