[0026] Working principle: When the controller 1 is working, the heat generated inside will be discharged through the heat dissipation holes 2.

Under the action of the first motor 4, the reciprocating screw 5 is driven to move back and forth in cooperation with the connecting frame 6 to drive the high-speed rotating fan 10, so that the heat above the heat dissipation holes 2 is quickly discharged to reduce the temperature inside the controller 1. When the controller 1 needs to be disassembled, just press down the pressure plates 16 on both sides to drive the slide bar 15 to drive the triangular block 14 along the inclined surface of the inclined surface block 13. The surface is slidable, so that the plug blocks 12 at both ends are retracted into the interior of the fixed box 11, and the spring 18 is compressed, so that the plug block 12 can be disengaged from the interior of the jack 22, thereby releasing the limiting effect of the controller 1, and then the controller 1 can be directly removed as a whole.

Under the restoring force of the spring 18, the plug block 12 is automatically snapped into the jack 22, completing the limited installation and fixation of the controller 1 without the help of tools.
