secondly, the small electric telescopic rod starts to contract to cause the push-pull rod to slide towards the connecting cylinder, so that the push-pull rod drives the connecting ring at the tail end of the main conducting wire to translate downwards to drive the conductive docking post inserted into the docking hole to move downwards to be separated from the elastic conductive clamping piece, namely, the main conducting wire is completely separated from the conductive position, when the U-shaped top frame at the lower side of the connecting ring at the tail end of the main conducting wire descends to contact with the slide block, the conductive docking post above the main conducting wire is already lower than the conductive docking post at the tail end of the auxiliary conducting wire, at the moment, when the small electric telescopic rod continues to drive the connecting ring at the tail end of the main conducting wire to descend through the push-pull rod, the tail end of the U-shaped top frame at the lower side rotates due to extrusion and is abutted to the docking convex sleeve at the left end of the slide block leftwards to push the slide block to slide leftwards along the first guide rail, so that the slide block drives the conductive docking post at the tail end of the auxiliary conducting wire to translate leftwards to be right below the docking hole, when the sliding block slides to the left end position along the first guide rail, the proximity inductive switch is triggered to start the electric guide rail, the first guide rail is driven to ascend upwards, the first guide rail is driven to move upwards through the sliding block and the U-shaped frame to move horizontally to the conductive butt joint column at the tail end of the auxiliary conductive wire right below the butt joint hole to ascend upwards and is inserted into the butt joint hole to contact with the elastic conductive clamping piece, the auxiliary conductive wire is connected into the circuit to switch a load circuit, and meanwhile, the connecting ring on the main conductive wire and the U-shaped top frame slide upwards to ascend along the second guide rail by virtue of the small electric telescopic rod due to the ascending action of the sliding block, so that the conductive butt joint column at the tail end of the auxiliary conductive wire is prevented from ascending;

the first step is as follows: when a second hand (17) on the mechanical clock (13) rotates for one circle, the contact induction switch (16) is triggered once, the contact induction switch (16) enables the small air pump (12) to operate, air is sucked from the inside of the insulation soft rubber wire sleeve (1), so that the insulation soft rubber wire sleeve (1) is shriveled due to the action of negative pressure, the temperature sensors (45) which are conveniently distributed on the inner wall of the insulation soft rubber wire sleeve (1) are close to the main electric wire (10), the temperature in the load process of sensing the main electric wire (10) is conveniently detected, meanwhile, the air outlet end of the small air pump (12) inflates the annular air pipes (43) at all positions through the communication hose (14), so that the annular air pipes (43) enable the corrugated telescopic air bags (44) at all positions to be inflated and stretched, the temperature sensors (45) connected at two ends are enabled to translate along the extension direction of the inner wall of the insulation soft rubber wire sleeve (1), and the temperature monitoring range is enlarged, meanwhile, air filled into the corrugated telescopic air bag (44) gradually leaks out of the small air leakage hole (46) finally, so that the corrugated telescopic air bag (44) is convenient to shrink and recover, and when the temperature sensor (45) at any position monitors that the temperature of the main conducting wire (10) at the current position is abnormally too high, the temperature sensor (45) enables the small electric telescopic rod (19) to shrink;

the second step is that: the small electric telescopic rod (19) starts to contract, so that the push-pull rod (35) slides towards the connecting cylinder (24), the push-pull rod (35) drives the connecting ring (41) at the tail end of the main conducting wire (10) to move downwards, the conductive butting column (39) inserted in the butting hole (36) is driven to move downwards to be separated from the elastic conductive clamping piece (37), namely, the main conducting wire (10) is completely separated from a conductive position, when the U-shaped top frame (33) at the lower side of the connecting ring (41) at the tail end of the main conducting wire (10) descends to contact with the sliding block (31), the conductive butting column (39) above the main conducting wire (10) is lower than the conductive butting column (39) at the tail end of the auxiliary conducting wire (11), and at the moment, when the small electric telescopic rod (19) continues to drive the connecting ring (41) at the tail end of the main conducting wire (10) to descend through the push-pull rod (35), the tail end of the U-shaped top frame (33) at the lower side rotates due to extrusion, and the sliding block (31) is abutted to a butt convex sleeve (30) at the left end of the sliding block (31) leftwards, and the sliding block (31) is pushed to slide leftwards along a first guide rail (29), so that the sliding block (31) drives a conductive butt column (39) at the tail end of the auxiliary conducting wire (11) to translate leftwards to be right below a butt hole (36), and when the sliding block (31) slides leftwards to the left end position along the first guide rail (29), a proximity inductive switch (57) is triggered to start an electric guide rail (27) to drive the first guide rail (29) to lift upwards, the first guide rail (29) drives the conductive butt column (39) at the tail end of the auxiliary conducting wire (11) translated to be right below the butt hole (36) to lift upwards through the sliding block (31) and a U-shaped frame (32), and is inserted into the butt hole (36) to contact with an elastic conductive clamp sheet (37), so that the auxiliary conducting wire (11) is accessed into a circuit to switch a load circuit, meanwhile, the connecting ring (41) on the main conducting wire (10) and the U-shaped top frame (33) slide upwards along the second guide rail (21) by virtue of the small electric telescopic rod (19) due to the lifting action of the sliding block (31), so that the conductive butt joint column (39) at the tail end of the auxiliary conducting wire (11) is prevented from being prevented from lifting;

the third step: in the line switching alternate process of the main conducting wire (10) and the auxiliary conducting wire (11) by downwards inserting the small electric telescopic rod (19) with the push-pull rod (35) into the connecting cylinder (24), the downwards moved push-pull rod (35) downwards pulls the pull rope (53), so that the pull rope (53) downwards pulls the movable end of the elastic conducting rotating sheet (54), the elastic conducting rotating sheet rotates to be close to the connecting conducting plate (38), and when the conducting butt-joint column (39) at the tail end of the main conducting wire (10) is separated from the butt-joint hole (36), the tail end of the elastic conducting rotating sheet (54) is just extruded onto the connecting conducting plate (38), the circuit connection between the storage battery pack (5) and the connecting conducting plate (38) is realized, so that the storage battery pack (5) temporarily supplies power for electric equipment butted by the electric socket (3) to avoid the use due to power failure, and in the process of downwards pulling the pull rope (53) by the push-pull rod (35), the tail end of the elastic conductive rotating sheet (54) is extruded, bent and attached to the connecting conductive plate (38) to keep electrifying, meanwhile, the other end of the elastic conductive rotating sheet (54) jacks up the sliding pipe (51) upwards through the insulating jacking head (52), so that the sliding pipe (51) slides upwards along the strip-shaped through hole (48) to lift up, a lead connected between the storage battery pack (5) and the elastic conductive rotating sheet (54) is driven to lift up together, and the connected lead is prevented from being pulled in the transition process of the rotation of the elastic conductive rotating sheet (54).
