As shown in fig. 2, when the rotation shaft 5 rotates clockwise, the first pawl 9 moves on the inclined surface 11 against the elastic force of the first torsion spring 13, the integrally rotating hold-down plate 7 does not rotate along with the rotation shaft 5, and when the rotation shaft 5 rotates counterclockwise, the straight surface 12 pushes the first pawl 9 to rotate due to the forward rotation of the straight surface 12, that is, after the first pawl 9 contacts with the inclined surface 11, the rotating hold-down plate 7 can rotate counterclockwise in synchronization with the rotation shaft 5. The state shown in fig. 2 is that the first pawl 9 contacts with the inclined plane 11, one convex rib 8 is vertically positioned in the wiring hole 2, at the moment, all wires in the wiring assembly are jacked up to be pressed and fixed, if the adjusting handle 6 is pushed to drive the rotating shaft 5 to rotate anticlockwise by 45 degrees in the direction shown in fig. 2, as shown in fig. 6, the convex rib 8 is not positioned in the wiring hole 2 any more, and the wires in all the wiring assemblies are in a pressed and fixed state, so that the wires can be uniformly detached.

When wires in all wiring assemblies are fixed and then the wires on the individual wiring assemblies need to be disassembled and replaced, a wire loosening hole 14 is formed in the wiring row 1 at the lower side of the wiring hole 2, the wire loosening hole 14 is communicated with the mounting cavity 4, a manual wire loosening device is mounted in the wire loosening hole 14, as shown in fig. 4, the manual wire loosening device comprises a U-shaped rod 15 arranged in the mounting cavity 4 and the wire loosening hole 14, the rib 8 is positioned in the U-shaped rod 15, and the U-shaped rod 15 can drive the rib 8 to rotate when being pulled out.
