The second screw 34 passes through the second fixing nut 211, the top plate 21, the second locking nut 33, and the lower part of the adjusting sleeve 35 in sequence from bottom to top.

[0029] Among the threads of the first screw 31 , the threads of the second screw 34 , the threads of the upper portion of the adjustment sleeve 35 , and the threads of the lower portion of the adjustment sleeve 35 , the direction of any one thread is opposite to the directions of the other three threads.

[0030] Preferably, the first fixing nut 111 is welded to the bottom plate 11 , and the second fixing nut 211 is welded to the top plate 21 .

[0031] In order to enhance the strength of the column connection assembly 2 , a stiffening rib 23 is provided between the top plate 21 and the positioning plate 22 .

[0032] The adjustable connector of the present invention is provided with an adjustment kit 35 of the first screw 31 and the second screw 34, and the direction of any one of the threads of the first screw 31, the thread of the second screw 34, the thread of the upper part of the adjustment kit 35 and the thread of the lower part of the adjustment kit 35 is opposite to the directions of the other three threads, so that by screwing the adjustment kit 35, the distance between the first screw 31 and the second screw 34 can be adjusted, thereby adjusting the distance between the hoop connection assembly 1 and the column connection assembly 2, ensuring the smooth connection of the adjustable connector and the steel column.

[0033] like Figure 4 As shown, the specific connection between the adjustable connector of the present invention and the I-beam 2' and the steel column 3' is as follows: the upper portion of the fixing plate 12 is provided with a snap-in interface 121 for receiving the I-beam 2'. Preferably, the snap-in interface 121 is in an inverted T-shape, so that the snap-in interface 121 snaps into the flange 31' and the web 32' of the I-beam 3'.

[0034] The screw hole plate 22 is specifically connected to the steel column 3' as follows: the positioning plate 22 is provided with a plurality of screw holes 221 for connection with the steel column 3'.

The thread of the first adjusting nut 352 is set to be a reverse thread, and the threads of the second adjusting nut 353, the first screw 35 and the second screw are all orthogonal threads. By rotating the adjusting kit 35 counterclockwise, the distance between the first screw 31 and the second screw 34 in the sleeve 351 can be closer, and by rotating the adjusting kit 35 clockwise, the distance between the first screw 31 and the second screw 34 in the sleeve 351 can be moved away, thereby adjusting the distance between the hoop connection assembly 1 and the column connection assembly 2.

[0038] Preferably, in order to strengthen the connection between the first adjusting nut 352 and the second adjusting nut 353 and the sleeve 351 , a reinforcing plate 354 is provided at the connection between the first adjusting nut 352 and the second adjusting nut 353 and the sleeve 351 .

[0039] More preferably, the reinforcing plate 354 is provided on a side surface of a connection between the first adjusting nut 352 and the sleeve 351 and on a side surface of a connection between the second adjusting nut 353 and the sleeve 351 .

[0040] In order to facilitate manual screwing of the adjustment kit 35 , two screwing handles 355 disposed opposite to each other are provided on the outer side wall of the sleeve 351 .

[0041] Preferably, the specific structure of the screwing handle 355 is that both ends of the screwing handle 355 are connected to the sleeve 351, and the middle part of the screwing handle 355 is away from the sleeve 351 to form a protrusion 355a for screwing.

[0042] In summary, the adjustable connector of the present invention can adjust the distance between the first screw 31 and the second screw 34 by adjusting the adjustment kit 35, thereby adjusting the distance between the hoop plate connection assembly 1 and the column connection assembly 2, ensuring smooth connection between the adjustable connector and the steel column. Secondly, the adjustable connector of the present invention can conveniently adjust the adjustment kit 35 by providing a first adjustment nut 352, a second adjustment nut 353, and a screw handle 355, thereby facilitating adjustment of the distance between the hoop plate connection assembly 1 and the column connection assembly 2.
