[0023] The outer walls of both sides of the fixing sleeve 12 are installed with a return spring 14, and the inner side of the return spring 14 is installed with a pressure rod 15, and one end of the pressure rod 15 is connected to a clamping block 16;

[0024] The outer wall above the positioning rod 10 is provided with a clamping groove 19 that matches with the clamping block 16, and the top cross-sectional view of the clamping groove 19 is circular;

[0025] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, when this structure is used, the circuit board body 9 is placed into the servo drive housing 8, so that the positioning rod 10 is positioned in the positioning hole 11, and then the movable plate 6 is rotated to move the fixing sleeve 12 above the positioning rod 10, and the threaded rod 7 is rotated and the threads are engaged, so that the threaded rod 7 drives the fixing sleeve 12 to descend to the top of the positioning rod 10 and get stuck, and then the locking sleeve 13 is rotated and the threads are engaged, so that the locking sleeve 13 is lowered so that the reset spring 14 and the pressure rod 15 are pressed inside, and the pressure rod 15 is squeezed so that the card block 16 is driven to get stuck inward into the card slot 19, which is convenient for the fixed installation of the circuit board body 9.
