In this process, if the connector 102 of the structure connected to the brushless DC motor control board is a connecting plug with a connecting wire, the two strip-shaped lower pressing plates 206 need to be rotated to the top of the connecting plug, and the connecting wire is located between the two strip-shaped lower pressing plates 206. If the structure connected to the brushless DC motor control board is other circuit boards, the two strip-shaped lower pressing plates 206 need to be rotated to At the top of the circuit board, when the above operations are completed, rotate the force column 209 counterclockwise, and the force column 209 will drive the adjusting screw 208 to rotate counterclockwise in the adjusting hole. The adjusting screw 208 rotating counterclockwise in the adjusting hole will drive the T-shaped lifting column 203 and the two strip lower pressure plates 206 to move vertically downward. When the two strip lower pressure plates 206 do not need to move further, stop rotating the force column 209. At this time, it can prevent the DC brushless motor control board connector 102 from loosening when connected to other structural connectors 102, thereby improving the stability of the connection between the DC brushless motor control board and other structures.
