[0048] The working principle of the present invention is as follows: when using the device, first open the dustproof plate 7, then start the electric telescopic rod 62, so that the electric telescopic rod 62 pushes the lifting plate 61 out of the storage box 1, and then rotates the baffle 68 to a vertical state, and then takes the handle 419 to drive the button rod 81 to be taken out of the placement slot 67, and then starts the motor 54, so that the output end of the motor 54 drives the winding roller 52 to rotate, and the wire 2 in the storage box 1 is transported out under the elastic clamping of the clamping roller 53 and the third spring 59, and at the same time, the wire 2 rolls on the sliding roller 9, and at the same time, the winding roller 52 drives the second gear 510 The second gear 510 drives the first gear 418 to rotate, and the first gear 418 drives the bidirectional screw 413 to rotate, and the bidirectional screw 413 drives the moving block 414 to slide relatively in the rectangular through hole 412, and the moving block 414 drives the rotating plate 415 to push the top plate 416 out of the rectangular through hole 412, and the top plate 416 unfolds the telescopic plate 417, so that the telescopic plate 417 supports the wires 2 transported out of the storage box 1, and the handle 419 is squeezed relatively, so that the handle 419 drives the limit plate 43 to rotate in the installation groove, and the limit plate 43 is stretched The first spring 44 compresses the first spring 44 and reduces the limit of the support plate 41 by the limiting plate 43, so that the support plate 41 drives the arc plate to rotate out and the arc plate is engaged with the edge of the charging port. At the same time, the support rod 46 rotates and slides out from the slide groove 45, and then the support rod 46 is moved so that the support rod 46 drives the limiting rod 49 to slide in the waist-shaped through hole 47. At the same time, the support rod 46 drives the slide plate 410 to slide in the slide groove 45 through the second spring 411. After adjusting the support position of the support rod 46, the support rod 46 is inserted into the first limiting groove 42 and the charging head 3 is released. The support rod 46 squeezes the second spring 411 to drive the limiting rod 49 to be inserted into the second limiting groove 48, and then the support plate 41 is started to make the support plate 41 drive the charging head 3 flush with the charging port. At the same time, the button rod 81 is pressed to make the button rod 81 squeeze the clamping plate 83, so that the clamping plate 83 slides in the shrinkage groove 82 to squeeze the special-shaped spring piece 85, so that the clamping plate 83 is in a compressed state. At the same time, the clamping plate 83 slides on the balance rod 84, and then the charging head 3 is inserted into the charging port. After releasing the button rod 81, the elastic reset ability of the special-shaped spring piece 85 drives the clamping plate 83 to be clamped in the charging port.

[0049] After charging is completed, repeat the above operation in reverse, retract the wire 2 into the storage box 1, and then take the charging head 3 and install it on the lifting plate 61. At the same time, make the charging head 3 squeeze the elastic plate 64, and make the elastic plate 64 squeeze the fourth spring 65, so that the fourth spring 65 and the elastic plate 64 are in a compressed state. At the same time, insert the button rod 81 into the placement groove 67, and then rotate the baffle 68 to horizontally block the handle 419 to facilitate stabilization of the charging head 3, and then retract the electric telescopic rod 62, so that the electric telescopic rod 62 drives the lifting plate 61 and the fixed plate 63 to retract into the storage box 1, and then cover the dustproof plate 7.
