At this time, the rotating rod 3 is controlled to rotate through the first linkage member to switch the position of the bearing relative to the opening groove. After the position switching of the bearing is completed, the clamping plate 14 is first controlled to complete the clamping of the outer wall of the bearing, and then the inner supporting plates 4 are controlled to slide inwards to release the bonding state with the inner wall of the bearing, so as to avoid the inner supporting plates 4 being in the position to be processed of the bearing, which causes the tool to damage the inner supporting plates 4 at that position when processing the bearing.
