When the coil 200 is mounted, the first driving rod 931 can be pushed by the second driving rod 932 to move upward and leftward to be closely abutted against the hole wall of the mounting hole of the coil 200. Because first drive rod 931 is rigid structure, when fastener 92 props up the pore wall of the mounting hole of coiled material 200, as long as second drive rod 932 does not pull first drive rod 931, fastener 92 and axis of rotation 91's distance can not change because of other external forces, can guarantee fastener 92 and coiled material 200 stable connection.
