Each split body 2 is in threaded connection with the bracket body 102 through a screw 3, an opening 200 is formed in the inner side of each split body 2, the opening 200 is semicircular, the split bodies 2 are mutually abutted in the first hole 101, and the openings 200 are surrounded to form a through hole through which the conical rotor 6 can pass.

Accordingly, in other embodiments of the present utility model, the shape of the split body 2 may be any shape other than a semicircle, which is only required to ensure that the split body 2 can pass through the conical rotor 6 after being enclosed, which is not limited in any way.

Further, referring to fig. 2 and 3, at least two open slots 202 are formed on the outer side of each split body 2, one portion of the elastic member 5 is abutted to the open slot 202, and the other portion of the elastic member 5 is abutted to the wall of the first hole 101. Preferably, the elastic member 5 is preferably a spring, and specifically, the spring is uniformly distributed on the outer side of the circular structure formed by encircling the split bodies 2, so as to ensure that the stress of the split bodies 2 is uniform.

Further, referring to fig. 1, the outer side of the bracket body 102 has a first protruding portion 100, a second hole 1030 for the screw 3 to be matched is formed in the first protruding portion 100, in the bracket structure for processing a conical rotor of this embodiment, the second hole 1030 is a through hole, and the second hole 1030 is in clearance fit with the screw 3, so that the screw 3 can move partially along the through hole.
