Angle tooth flange convenient to position

The utility model relates to the technical field of automobile parts, in particular to an angle tooth flange convenient to position, which comprises an upper flange, a lower flange, a sleeve, a positioning insertion block and an insertion groove, and the lower flange is fixedly connected with the upper flange through a bolt penetrating through a screw hole; the two sleeves are respectively mounted on the upper flange and the lower flange; the positioning insert is connected to the lower end of the upper flange; the inserting grooves are formed in the lower flange and are in clearance fit with the positioning inserting blocks. Through the matching of the positioning insertion blocks and the insertion grooves between the upper flange and the lower flange, the effect of positioning the screw holes of the two flanges to be aligned is achieved, the dislocation phenomenon is effectively prevented, and through the arc angles on the positioning insertion blocks and the insertion grooves, the opening of the insertion
