The PLC control cabinet that is easy to install and wire adjusts the position of the PLC control box, reduces the impact of space limitations on wiring work, and facilitates wiring work for workers. However, while solving the problem, the PLC control cabinet that is easy to install and wire has the following defects:

[0004] After the wiring of the device is completed, when wiring is carried out, the sliding plate is pulled to compress the reset spring of the connecting block, so that the staff can place the connecting wire into the fixed mouth of the wiring plate, and then release the sliding plate. Under the action of the reset spring, the connecting block can be driven to reset, and the sliding plate is reset to clamp the connecting wire. After clamping the connecting wire at one end, the remaining connecting wires need to be sorted out by the user, which is time-consuming and labor-intensive. If they are not sorted out, not only will the lines be messy, but there will also be flying wires, etc., which will undoubtedly be troublesome for the user when replacing the connecting wires later.
