The first sliding rod 412 drives the second sliding rod 413 to move, and through the second sliding rod 413, drives the positioning rod 316 to slide along the inner wall of the movement groove 317, thereby driving the rotating block 319 to rotate.

The third connecting rod 321 drives the driving shaft 324 to move through the moving frame 325, and the driving shaft 324 drives the pressing block 327 to move to clamp the cable.

[0041] (2)Meanwhile, push the connecting rod 305. The connecting rod 305 drives the sliding plate 308 to slide along the inner wall of the first chute 303 through the vertical shaft 304. The sliding plate 308 drives the first connecting rod 309 to move. The first connecting rod 309 drives the first connecting shaft 311 to move. The first connecting shaft 311 drives the first slider 312 to slide along the second chute 310. The first connecting shaft 311 drives the moving shaft 315 to slide along the third chute 314 through the second connecting rod 313, thereby completing the docking of the positioning rod 316 and the moving shaft 315, and further completing the fixation of the positioning rod 316. Then, fix the moving plate 306 to the side of the main body plate 101 through the fixing bolt 307.

[0042] When the sliding plate 308 moves, it drives the fifth connecting rod 511 to move. The fifth connecting rod 511 drives the third slider 513 to slide along the sixth chute 512. The third slider 513 drives the seventh sliding rod 509 to move through the ninth connecting shaft 510. The seventh sliding rod 509 drives the fifth sliding rod 507 to rotate around the eighth connecting shaft 506 through the sixth sliding rod 508. The fifth sliding rod 507 drives the third sliding rod 504 to move through the fourth sliding rod 505. The third sliding rod 504 drives the sliding conductive rod 502 to slide along the transfer conductive rod 501 through the seventh connecting shaft 503, thereby completing the connection of the sliding conductive rod 502 to the cable, and thus realizing the feeding of the electrical energy of the cable into the battery 2, and powering the electromagnet 104 through the battery 2 to adsorb the whole device beside the electricity meter to be replaced.
