[0010] As a further solution of the utility model, the length of the arc block is half a circle of the annular groove, and the arc blocks in the two annular grooves are respectively located at opposite positions of the two annular grooves.

[0011] As a further solution of the utility model, the fixing columns on one side of the two flange bodies are staggered and distributed, and the through grooves on one side of the two flange bodies are staggered and distributed.

[0012] As a further solution of the utility model, the rubber balls on one side of the two flange bodies are distributed alternately, and the grooves on one side of the two flange bodies are distributed alternately.

[0013] The beneficial effects of the utility model are:

[0014] 1. Through the coordinated use of arc blocks, annular grooves, fixing columns and through grooves, when fixing the two flanges, the arc blocks on the two flanges are made to enter the annular grooves, so that the two arc blocks form a circle, and at the same time, the fixing columns pass through the through grooves to position the two flanges. At this time, the mounting holes on the two flanges are aligned, thereby preventing the two flanges from shifting when fixed, facilitating the alignment of the mounting holes on the two flanges, saving time and improving efficiency.

[0015] 2. Through the coordinated use of the rubber balls and the grooves, when the two flanges are fixed, the rubber balls on the two flanges are respectively inserted into the grooves, so that the two flanges can be repositioned, thereby improving the accuracy of flange positioning.
