[0028] The nut fixing plate 6 in the nut fixing assembly is fixedly connected to the bend of the U-shaped locking frame 2, and the inner surface of the nut fixing plate 6 is an inclined surface adapted to the nut;

[0029] The locking nut 8 is located in the nut fixing plate 6. The outer surface of the locking nut 8 is provided with a cleaning groove 9 for cleaning residual concrete on the threaded steel wire teeth. Two sliding holes 16 are both opened on the outer surface of the fixing block 1, and the two vertical rods of the U-shaped locking frame 2 are both slidably connected in the corresponding sliding holes 16.

[0030] Furthermore, the fixing plate 3 is fixedly connected to the upper end of the opening of the U-shaped locking frame 2 , and the stud 5 is slidably connected in the fixing plate 3 .

[0031] Furthermore, the stud 5 is rotatably connected to the fixing block 1, and the fixing plate 3 is rotatably connected to a repair nut 4 on a side close to the fixing block 1. A handle is provided on the repair nut 4, and the repair nut 4 is used to drive the nut fixing plate 6 to lock the locking nut 8.

[0032] Furthermore, the hexagonal sleeve 7 is fixedly connected to the end of the stud 5 away from the fixed block 1, the hexagonal sliding shaft 10 is slidably connected in the hexagonal sleeve 7, and the end of the hexagonal sliding shaft 10 extending out of the hexagonal sleeve 7 is rotatably connected to a rotating handle 11 for applying force.

[0033] Furthermore, a hand screw 12 is threadedly connected to the opening of the hexagonal sliding sleeve 7 , and the hand screw 12 is used to adjust the extension length of the fixed hexagonal sliding shaft 10 . A strong magnetic fixing groove 13 is provided on the outer surface of the fixing block 1 .

[0034] Furthermore, a strong magnetic ring 14 is provided in the strong magnetic fixing groove 13 . The strong magnetic ring 14 is fixed to the fixing block 1 through screws 15 . The strong magnetic ring 14 is used to axially position the locking nut 8 .

[0035] Furthermore, when in use, a cleaning groove 9 is opened on the surface of the nut that matches the threaded steel bar, and then the locking nut 8 is placed on the fixing block 1. At this time, the locking nut 8 will be attracted by the strong magnetic ring 14, and then the handle on the repair nut 4 is fixed by one hand, and the hexagonal sleeve 7 is twisted with the other hand, which can make the stud 5 rotate. When the stud 5 rotates, it can drive the nut fixing plate 6 and the fixing block 1 to approach each other. At this time, the inclined surface of the nut fixing plate 6 will contact the locking nut 8, thereby fixing the locking nut 8 on the fixing block 1, and then the locking nut 8 is screwed twice on the threaded steel bar. After ensuring that the locking nut 8 is level with the steel bar, manually drive the hexagonal sleeve 7 to rotate on the threaded steel bar and start threading.

At this time, the operator can support the hexagonal slide shaft 10 with one hand and hold the rotating handle 11 with the fixed block 1 with the other hand. At this time, the operator can clean the concrete residue on the concrete thread with more effort. This design makes the operation more flexible and convenient, reduces the difficulty of operation and physical exertion, and avoids the traditional cleaning method that requires using a lot of force or relying on other tools to turn the nut, which is not only time-consuming and labor-intensive but also ineffective. The tool and method, through the improved design, enable the operator to deal with this situation more easily, improving the cleaning effect and efficiency.

[0037] Working principle: When in use, a cleaning groove 9 is opened on the nut surface that matches the threaded steel bar, and then the locking nut 8 is placed on the fixing block 1. At this time, the locking nut 8 will be attracted by the strong magnetic ring 14, and then the handle on the repair nut 4 is fixed with one hand, and the hexagonal sleeve 7 is twisted with the other hand, which can make the stud 5 rotate. When the stud 5 rotates, it can drive the nut fixing plate 6 and the fixing block 1 to approach each other. At this time, the inclined surface of the nut fixing plate 6 will contact the locking nut 8, thereby fixing the locking nut 8 on the fixing block 1, and then screw the locking nut 8 on the threaded steel bar with two threads. After ensuring that the locking nut 8 is level with the steel bar, manually drive the hexagonal sleeve 7 to rotate on the threaded steel and start threading. Concrete residue will fall along the cut of the cleaning groove 9 until all the concrete falls off the threaded teeth. Rotate the hexagonal sleeve 7 in the opposite direction, withdraw the nut, and the threaded teeth are repaired.

[0038] Furthermore, when encountering a threaded steel bar that is difficult to turn, by loosening the hand screw 12, the hexagonal sliding shaft 10 is freed from the restriction of the hand screw 12 and can be pulled out from the hexagonal sliding sleeve 7, and then the rotating handle 11 is turned out. At this time, the operator can support the hexagonal sliding shaft 10 with one hand and hold the rotating handle 11 with the fixed block 1 with the other hand. At this time, the operator can clean the concrete residue on the concrete thread more effortlessly.
