[0037] Working principle: When the device is in use, the device is placed in the use position through the outer frame 11, the snap-fit ​​frame 18 is placed on the surface of one end of the four snap-fit ​​plates 17, the four snap-fit ​​structures 2 are inserted into the snap-fit ​​frame 18 and the snap-fit ​​plates 17 to make the snap-fit ​​balls 25 shrink inward, the turning handle 22 is rotated to make the moving column 23 rotate synchronously, so that the pressing column 24 is pressed against the surface of the snap-fit ​​ball 25, so that the snap-fit ​​ball 25 moves outward, and one side of the snap-fit ​​ball 25 is snapped on the surface of the other end of the four snap-fit ​​plates 17, limiting the four sets of current converters 16.
