[0022] Working principle: Pass the wire through the wire holes on the back plate 3 and the moisture absorption pad 4 so that the wire is inserted into the second wiring groove and connected to the first conductive column 515. Insert the sliding plate 52 and the support plate 521 into the first mounting plate 51 and the connecting plate 512 so that the support plate 521 can slide on the surfaces of the connecting plate 512 and the first mounting plate 51. Insert the hand into the grasping groove, take out the main board 55 and the plug board 551 from the designated wiring groove, and insert them into the wiring groove and the placement groove that the support plate 521 needs to pass through, so that the support plate 521 can smoothly pass through the wiring groove and the placement groove to reach the designated position. When the support plate 521 reaches the designated position, the spring 525 pushes the third electrode piece 524 so that the third electrode piece 524 contacts the first motor piece 514. Then, place the ammeter 53 on the upper surface of the support plate 521 so that the electrode column on the ammeter 53 is inserted into the first wiring groove and contacts the second electrode piece 522, thereby connecting the ammeter to the circuit.

When the sliding plate 52 needs to be replaced, the wiring groove on the connecting plate 512 has an arc surface, and both sides of one end of the third electrode piece 524 inserted into the wiring groove also have an arc surface. When the connecting plate 512 is pushed forcefully, under the action of the arc surface, the third electrode piece 524 will be pushed into the support plate 521, so that the support plate 521 slides on the surfaces of the first mounting plate 51 and the connecting plate 512, thereby enabling the replacement of the sliding plate 52, thus improving the operation efficiency and reducing the maintenance difficulty. When not in use, the main board 55 and the plug board 551 are inserted into the wiring groove to avoid dust contamination of the surface of the first motor piece 514. The moisture absorption pad 4 can absorb the moisture in the air, ensuring the dryness inside the cabinet 1.
