A plug-in slot 11 adapted to the plug-in block 9 is provided on the docking block 10. A mounting block 7 is slidably installed on the mounting plate 3. A transmission cavity 14 is provided in the mounting block 7. A driving gear 8 is rotatably installed in the transmission cavity 14. Two transmission sliders 15 are slidably installed in the transmission cavity 14. A limit plug rod 12 penetrating the transmission cavity 14 and extending to the outside is installed on the transmission slider 15. Both the plug-in block 9 and the docking block 10 are provided with a socket 13 adapted to the limit plug rod 12. Both the two transmission sliders 15 are provided with a transmission tooth groove 18 meshing with the driving gear 8.

[0023] By means of the structures such as the mounting plate 3, the docking block 10 and the plug-in block 9, the mounting plate 3 can be first fixed to the wall during use, and then the two plug-in blocks 9 on the grounding box 1 can be inserted into the plug-in slots 11 on the two docking blocks 10 on the mounting plate 3, and then the active gear 8 in the mounting block 7 is rotated to drive the two transmission slide blocks 15 away from each other, so that the limiting plug rod 12 on the transmission slide block 15 passes through the plug holes 13 on the docking block 10 and the plug-in block 9 in turn, thereby realizing the connection and fixation between the grounding box 1 and the mounting plate 3, and completing the installation process of the wall-mounted grounding box 1. When the grounding box 1 needs to be disassembled, the active gear 8 can be rotated in the reverse direction to make the limiting plug rod 12 release the connection and fixation between the docking block 10 and the plug-in block 9, and the grounding box 1 can be removed along the plug-in slot 11 to complete the disassembly process.
