The adjustment protrusion and the inclined auxiliary adjustment groove cause the drive adjustment block to retract and fold. S300, Connection Processing: For connecting wires with mounting copper clips: by rotating the guide shaft with drive screw teeth, the secondary drive adjustment shaft and the primary drive key shaft are pushed to move, causing the drive adjustment block to be inserted into the mounting hole of the electrical unit connection end; then, the mounting copper clips of the wires with mounting copper clips are manually fitted onto the connection part A in sequence; by rotating the drive shaft, the drive wheel drives several synchronous wheels to rotate, causing the fixedly connected secondary drive adjustment shaft to remain stationary, while the primary drive key shaft retracts relative to the rotation. The drive adjustment block is kept in the hinge center position by the radial limiting protrusion and the centrally hinged sliding groove, and the drive adjustment block is rotated and unfolded by the adjusting protrusion and the inclined auxiliary adjusting groove. If connecting wires without copper clips: Based on step S200, manually clip the exposed ends of the wires with copper clips into the transition grooves one by one. S400, Fastening treatment: If the wire with copper clip is fastened: by rotating the guide shaft with drive screw teeth in the positive direction, the first-stage drive key shaft and the second-stage drive adjustment shaft are retracted as a whole, and the wire with copper clip is tightly attached to the electrical unit connection end under the hook of the drive adjustment block. To tighten wires without copper clips: By rotating the guide shaft with drive screw teeth in opposite directions, the first-stage drive key shaft and the second-stage drive adjustment shaft are pushed forward as a whole. Under the clamping of the drive adjustment block, the exposed end of the wire is squeezed into the electrical unit connection end channel in a "V" shape.
