The present invention has the following beneficial effects:

1. The energy-saving power cabinet first inserts the cable body into the threading hole from bottom to top, pushes the second push rod, so that the clamping ball is inserted into the clamping groove, so that the wire fixing ring contacts the side of the cable body, repeats the above operation, and thus fixes several cable bodies on the side of the wire fixing frame, then presses the first push rod, so that the first push rod drives the second wedge block to move upward, and through the cooperation of the first wedge block and the second wedge block, the first wedge block drives the positioning rod to slide out of the positioning groove, so that the wire fixing frame can slide up and down, pushes the wire fixing frame upward, so that the wire stripper cuts off the insulation layer at the end of the cable body, and not only that, continues to push the wire fixing frame upward, through the setting of the driving component, the wire stripper moves upward relative to the wire fixing frame, so that the cut insulation layer is stripped off, exposing the cable core therein;

Subsequently, the fixing frame is pushed up continuously so that the cable core slides to the upper side of the first connecting piece. At the same time, the fourth wedge block is moved up with the fixing frame and collides with the third wedge block. Through the coordinated use of the third wedge block and the fourth wedge block, the third wedge block is moved backward and the third spring is compressed, so that the third wedge block drives the pin to slide out of the connecting frame, so that the second connecting piece is flipped downward under the action of the rebound force of the torsion spring, and the cable core is pressed tightly between the first connecting piece and the second connecting piece, completing the electrical connection between the cable body and the meter body, and the positioning rod is slidably inserted into the positioning groove at the upper end to fix the wire fixing frame, thereby improving the wiring efficiency of the energy-saving power cabinet.

2. The energy-saving power cabinet first drives the first limiting ball to slide from the first groove into the second groove through the upwardly moving wire fixing frame, so that the first connecting rod drives the first arc knife to approach and close the second arc knife, so that the first arc knife and the second arc knife cut the insulation layer, and then the wire fixing frame drives the gear to continue to move upward, so that the gear is engaged with the second rack, driving the gear to rotate, and at the same time, the engagement of the gear with the first rack drives the second connecting rod to move upward relative to the wire fixing frame, pulls up the slide bar and stretches the second spring, so that the second connecting rod drives the first arc knife and the second arc knife to move upward relative to the cable body, and pushes the cut insulation layer out from the upper end of the cable core, so as to facilitate stripping the insulation layer at the end of the cable body to expose the cable core therein;

In the above process, the second limit ball slides in the shallow groove, and then the second limit ball slides from the shallow groove into the deep groove, so that the control rod drives the gear to separate from the first rack and the second rack. Under the action of the second spring rebound force and the wire stripper's own gravity, the first arc knife and the second arc knife drop and reset, avoiding obstruction to the connection between the cable core and the first wiring piece and the second wiring piece, making it easier to connect the cable body and the meter body, thereby further improving the wiring efficiency.

3.

In this embodiment: First, the first limiting ball 146 is driven by the upwardly moved wire fixing frame 120 to slide from the first groove 1471 into the second groove 1472, so that the first connecting rod 141 drives the first arc knife 1401 to approach and close the second arc knife 1402, so that the first arc knife 1401 and the second arc knife 1402 cut the insulating layer 1302, and then the wire fixing frame 120 drives the gear 154 to continue to move upward, so that the gear 154 is meshed with the second rack 155, driving the gear 154 to rotate, and at the same time The second connecting rod 142 is driven to move upward relative to the cable fixing frame 120 through the meshing of the gear 154 and the first rack 151, and the sliding rod 143 is pulled upward and the second spring 144 is stretched, so that the second connecting rod 142 drives the first arc knife 1401 and the second arc knife 1402 to move upward relative to the cable body 130, and the cut insulating layer 1302 is pushed out from the upper end of the cable core 1301, so as to facilitate the stripping of the insulating layer 1302 at the end of the cable body 130 to expose the cable core 1301 therein;

In the above process, the second limiting ball 156 slides in the shallow groove 1571, and then the second limiting ball 156 slides from the shallow groove 1571 into the deep groove 1572, so that the control rod 153 drives the gear 154 to separate from the first rack 151 and the second rack 155. Under the action of the rebound force of the second spring 144 and the gravity of the wire stripper 140 itself, the first arc knife 1401 and the second arc knife 1402 descend and reset, avoiding obstruction to the connection between the cable core 1301 and the first wiring piece 160 and the second wiring piece 170, facilitating the connection between the cable body 130 and the meter body 110, thereby further improving the wiring efficiency.

It should be noted that: when the device is disassembled, the wire fixing frame 120 moves downward and resets, and the second limiting ball 156 slides down in the deep groove 1572, so that the gear 154 is always separated from the first rack 151 and the second rack 155. When the second limiting ball 156 slides down to the lowest point, the second limiting ball 156 squeezes the blocking piece 158, so that the upper end of the blocking piece 158 flips toward the direction of the shallow groove 1571, so that the second limiting ball 156 slides into the shallow groove 1571 again, and the second limiting ball 156 is reset. When the second limiting ball 156 moves up again, due to the obstruction of the blocking piece 158, the second limiting ball 156 can only move up along the shallow groove 1571.
