[0015] 2. The second sliding frame slides in the second sliding groove driven by the electric telescopic rod, thereby driving the pressure plate to move downward, so that the pressure plate is pressed on the motor end ring, thereby fixing the motor end ring, thereby preventing the motor end ring from deviating during processing and improving the quality of hole expansion.
