[0028] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0029] Please refer to Figures 1 to 3The utility model provides a combined die wrench, comprising a half die body 1 and a fixing mechanism 2 arranged in pairs;

[0030] Pairs of half die bodies 1 are spliced ​​together to form a complete die wrench;

[0031] The fixing mechanism 2 is connected to the die wrench to fix the spliced ​​half die body 1;

[0032] When in use, the paired half-die bodies 1 can be directly disassembled, and after aligning with the complete thread of the bolt that needs to be repaired, the two half-die bodies 1 can be spliced ​​together to form a complete die wrench, and then the two half-die bodies 1 can be fixed by the fixing mechanism 2 to repair the bolt. The application can be quickly installed on the bolt that needs to be repaired, thereby improving the repair efficiency of the bolt and is suitable for large-scale promotion and use.

[0033] In this embodiment, a connecting protrusion 11 is provided on one of the half-tooth bodies 1, and a connecting groove 12 corresponding to the connecting protrusion 11 is provided on the other half-tooth body 1. With the cooperation of the connecting protrusion 11 and the connecting groove 12, the two half-tooth bodies 1 can be accurately docked and tightly fitted, thereby avoiding a height difference between the two half-tooth bodies 1.

[0034] In this embodiment, the fixing mechanism 2 includes two arc-shaped parts 21 and a fixing assembly 22. The two arc-shaped parts 21 are connected by a hinge. The half-tooth body 1 can be detachably installed in the corresponding arc-shaped part 21. The fixing assembly 22 is used to fix the free ends of the two arc-shaped parts 21 together. The two half-tooth bodies 1 are fixed by a clamp, which is convenient and quick to use.

[0035] In this embodiment, the fixing assembly 22 includes a connecting ear 222, a screw rod 223, a bolt seat 224, a connecting seat 221 and a limit block;

[0036] One end of the connecting ear 222 is hinged to the free end of one of the arc-shaped members 21;

[0037] The connecting seat 221 is fixed in the connecting ear 222, and a through hole corresponding to the screw rod 223 is formed in the connecting seat 221;
