When the conical block 223 contacts the right side of the movable arm 211, the movable arm 211 will be pushed. Since the movable arm 211 rotates on the fixed frame 13, the left side of the movable arm 211 will drive the clamping block 121 to be close to the roller bearing 11, so as to quickly fix the roller bearing 11.
