[0049] Working principle: the function of the upper cover plate 2 and the lower cover plate 3 is to provide connection for the line body; the function of the display screen 4 is to display the status of the frequency converter; the function of the sixth interface 6 and the eighth interface 8 is to facilitate the connection of the line body; when installing the frequency converter, turn the handle 20 to rotate; the rotation of the handle 20 drives the rotary rod 22 to rotate through the support of the support sleeve 18; the rotation of the rotary rod 22 drives the threaded sleeve 21 to move; the movement of the threaded sleeve 21 drives the pressing plate 11 to move; the movement of the pressing plate 11 drives the limiting cylinder 10 to move through the support of the sliding rod 9; the movement of the pressing plate 11 makes the excitation head 14 contact with the connection; the movement of the excitation head 14 drives the pull-back spring 13 to move; the pull-back spring 13 moves the excitation head 14 The touch sensor 12 contacts the touch sensor 12, and the touch sensor 12 controls the electromagnetic block 17 to start through the processor 7, so that it generates magnetic force to quickly adsorb and fix the frequency converter. When replacing the frequency converter, the handle 20 is reversed to make the excitation head 14 move away from the touch sensor 12. At this time, the processor 7 controls the electromagnetic block 17 to be closed to make it quickly removed, thereby realizing the function of quickly replacing the frequency converter and increasing the replacement efficiency. The function of the placement rack 23 is to provide support for the hair dryer 24, and the function of the limit column 27 is to provide a mobile limit for the grid 29. The touch sensor 12 controls the electric telescopic rod 25 to move through the processor 7, and the movement of the electric telescopic rod 25 drives the latch 26 to move, and the latch 26 moves to move into the bayonet 30. At the same time The processor 7 controls the hair dryer 24 to rotate and generate wind force, so that the frequency converter dissipates heat quickly. When the excitation head 14 moves away from the touch sensor 12, the processor 7 controls the electric telescopic rod 25 to move. The electric telescopic rod 25 moves to move the latch pin 26 out of the latch 30. At this time, the grid frame 29 is pulled to make it quickly move out for easy cleaning, thereby realizing the function of quickly moving the frequency converter grid frame 29 out for easy cleaning and reducing manual labor. The function of the limit plate 38 is to provide support for the tension spring 39, and the function of the slide cylinder 35 is to provide mobile support for the pull rod 36. The movement of the pull rod 36 drives the tension spring 39 to move. The movement of the tension spring 39 causes the pull rod 36 to drive the pressure head 37 to move. The pressure head 37 moves to open the wire release path 33. When the connecting wire is placed in the wire release channel 33, the pull rod 36 is released and the tension spring 39 drives the pressure head 37 to press the connecting wire toward the friction bar 34, so that the connecting wire is fixed to prevent displacement, thereby realizing the function of fixing the wiring to prevent line confusion and facilitate repair. The exposed part of the wire is placed in the connecting port 42, and the screw 44 is rotated by a tool at this time. The screw 44 rotates so that it is supported by the screw sleeve 43 and is pressed down. The movement of the screw 44 drives the pressure line 46 to move. The pressure line 46 moves to press the exposed part of the wire to the tip 50 to move the tip 50. The movement of the tip 50 drives the buffer block 48 to move. The movement of the buffer block 48 enhances the installation stability of the wire, thereby realizing the function of enhancing the installation stability of the inverter wire.
