[0025] During operation, through the opening of the limiting groove 31 of the support column 21, when the support column 21 is installed inside the mounting plate 27, the limiting pin 29 passes through the limiting groove 31 to limit the support column 21 to prevent the support column 21 from moving during operation.

[0026] Furthermore, the wrench 1 is provided with a fixed jaw 11, a mounting groove 12 is provided on one side of the fixed jaw 11, a fixed pin 13 is fixedly installed inside the mounting groove 12, an open adjustment nut 14 is movably installed around the fixed pin 13, a movable jaw 15 is threadedly connected to one side of the open adjustment nut 14, and one side of the movable jaw 15 is movably installed with the fixed jaw 11;

[0027] During operation, the nut is clamped through the gap between the fixed jaw 11 and the movable jaw 15 to achieve installation and removal of the nut. When encountering a nut of inconsistent specifications, the movable jaw 15 is displaced by moving the opening adjustment nut 14 to ensure adaptability to the installed nut.

[0028] Furthermore, a first rubber grip 16 is fixedly mounted on one side of the fixed jaw 11, a support column 21 is fixedly mounted on one end of the fixed jaw 11, and a second rubber grip 25 is fixedly mounted on one side of the support column 21;

[0029] During work, the first rubber grip 16 and the second rubber grip 25 are installed so that the operator can hold the handle while working.

[0034] Furthermore, a limit strip 34 is fixedly mounted on one side of the mounting plate 27, and a support column 21 is fixedly mounted on one side of the limit strip 34;

[0035] During operation, by installing the limiting strip 34 , the limiting strip 34 is helpful to assist in limiting one side of the support column 21 , so that the support column 21 cannot shake during operation.

[0036] Working principle: personnel move the open adjusting nut 14, and the open adjusting nut 14 is threadedly matched with the movable jaw 15 when rotating, causing the movable jaw 15 to move relatively. As the movable jaw 15 is continuously adjusted, the wrench 1 is matched with the nut to adapt to the installation and disassembly of nuts of different specifications. When encountering a cylindrical or tubular nut, the wrench 1 will not be able to work at this time. By rotating the threaded sleeve 26 on the other side, the threaded sleeve 26 is also threadedly matched with the threaded column 24. As the threaded column 24 moves vertically, the cylindrical or tubular nut is placed between the fixed tooth head 22 and the movable tooth head 23. When the threaded column 24 moves, the fixed tooth head 22 and the movable tooth head 23 clamp the two sides of the cylindrical or tubular nut to limit the cylindrical or tubular nut so as to perform installation and disassembly work on the cylindrical or tubular nut.
