The card slot 42 is used to clamp the card plate 41 onto the second copper bar 3, and the arc pressing 43 is clamped onto the first charging resistor 15, and then the connecting plate 46 is pressed to make the connecting plate 46 clamped into the inner side of the first hidden groove 44, and one end of the connecting plate 46 is clamped into the inner side of another group of second hidden grooves 47, so that the two groups of card plates 41 are connected, and then the limiting piece 413 is rotated to press the connecting plate 46 tightly, At the same time, the second spring 421 will push the slider 419 out from the inner side of the slide groove 418, and will clamp the connecting plate 46 that is stuck on the inner side of the second hidden groove 47. At the same time, the downward movement of the sliding shaft 45 will use the pressure seat 48 to press the rotating rod 49 downward. The rotating rod 49 drives the rotating block 417 to rotate inside the opening 416, and at the same time, it will push the top shaft 411 out from one end of the through hole 410. The two groups of top shafts 411 are respectively pressed against the second copper sheet 12 and the third copper sheet 13 to ensure the stability of the second copper sheet 12 and the third copper sheet 13.
