The picking and rotating assembly 131 rotates a predetermined angle to move the circlip to the picking position of the picking and transferring assembly 132. Specifically, the picking and rotating assembly 131 is located on the side of the circlip positioning groove 113. After the picking and rotating assembly 131 clamps the circlip, it rotates about 90 degrees to move the circlip to the picking position of the picking and transferring assembly 132.
