When it is necessary to adjust the space of the power distribution cabinet, turn on the drive motor 28, and the output end of the drive motor 28 rotates to drive the threaded rod 24 to rotate. The rotation of the threaded rod 24 drives the threaded block 25 to move upward, thereby driving the L-shaped plate 26 to move upward. The upward movement of the L-shaped plate 26 drives the extension plate 27 to move upward, so that the space inside the power distribution cabinet is increased.

[0041] Compared with the related art, the detachable high and low voltage distribution cabinet provided by the utility model has the following beneficial effects:

[0042] The threaded rod 24 is driven to rotate by the driving motor 28, thereby driving the threaded block 25 to move upward, and then driving the L-shaped plate 26 to move upward, and further driving the extension plate 27 to move upward, so as to adjust the internal space of the distribution cabinet. The structure is simple and practical, so that the device can meet the needs of increasing the internal space of the distribution cabinet without disassembling the components of the distribution cabinet, solving the problem of insufficient internal space and need to reassemble components when the distribution cabinet is in use, reducing the workload of operators, and thus bringing convenience to operators.
