[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in places where the load is relatively dispersed and there are fewer circuits; the motor control center is used in places where the load is concentrated and there are more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] A distribution cabinet is a container for holding electrical equipment. During the production process of the distribution cabinet, the shell needs to be cut into a suitable size. Marks are generally made on the shell between cuts, and then the marks are aligned with the circular saw during cutting. In the prior art, the shell needs to be moved to align the marks with the circular saw, and the alignment process is quite inconvenient.

Mark one end of the material to be cut, and then place the material flat on the top of the box so that it is located between the two positioning bars, and the marked end is facing the benchmark. Then the screw is rotated by the handwheel to drive the slide bar to move along the slide until the benchmark and the mark are aligned. When the slide bar moves, it will drive the circular saw to move along the main shaft through the U-shaped part. When the benchmark and the mark are aligned, the circular saw and the mark are also aligned. Then start the motor, and the motor output shaft drives the main shaft and the circular saw to rotate, and then push the material along the positioning bar, so that the material can be cut along the marked position by the circular saw.
