[0042] The nut 4 is threadably matched with the second end of the bolt 3 to fix the blade 5 on the mounting surface 12 .

[0043] It should be noted that, since the first end of the bolt 3 of the present application is clamped with the bolt holder 2, after the thread of the bolt 3 fails, the blade 5 can be firmly fixed on the blade hub 1 by replacing the bolt 3.

[0044] After replacing the bolt 3 , the through hole 51 of the blade 5 needs to be aligned with the bolt 3 , and then the blade 5 can be firmly fixed to the blade hub 1 through the cooperation of the nut 4 and the bolt 3 .

[0045] It is worth noting that one mounting surface 12 of the present application can be embedded with one bolt holder 2 or multiple bolt holders 2. Technical personnel in this field can make a choice according to their needs. By embedding multiple bolt holders 2 on one mounting surface 12, the blade 5 can be fixed by multiple bolts 3 and nuts 4, which can further improve the strength of fixing the blade 5.

[0046] It should also be noted that, since the cutter hub 1 is mounted on a rotating shaft, a mounting hole 11 cooperating with the rotating shaft is provided in the axial direction of the cutter hub 1 of the present application.

[0047] In the present application, when the bolt 3 is installed, it is preferred that the bolt 3 is installed perpendicular to the installation surface 12 .

[0048] The embodiment of the utility model provides a mounting hole 11 for cooperating with the mounting shaft in the axial direction of the cutter hub 1, provides a plurality of mounting surfaces 12 in the circumferential direction of the cutter hub 1, embeds the bolt holder 2 in the mounting surface 12, and clamps the first end of the bolt 3 with the bolt holder 2, and provides a through hole 51 for the bolt 3 to pass through the blade 5, and then fixes the blade 5 to the mounting surface 12 by threading the nut 4 with the second end of the bolt 3. Through the rotary shearing crusher combined tool disclosed above, since the bolt 3 of the present application is clamped with the bolt holder 2, when the bolt 3 fails, the fixing of the blade 5 can be ensured by replacing the bolt 3. Compared with the existing combined tool with threaded holes on the cutter hub 1, the present application effectively avoids the time-consuming and laborious problems caused by replacing the cutter hub due to the failure of the thread of the screw hole. Moreover, since the present application does not need to provide threaded holes on the cutter hub 1, the present application can effectively ensure the strength of the cutter hub 1.

[0072] It should also be noted that, during the installation of the blade 5 , the protrusion 13 can cooperate with the groove 52 of the blade 5 to achieve rapid positioning, thereby improving the assembly efficiency of the blade 5 .

[0073] Furthermore, the rotary shearing crusher combined cutter further comprises: a plurality of positioning members 6 arranged on the mounting surface 12;

[0074] The blade 5 is provided with a positioning groove 53 which cooperates with the positioning member 6 .
