[0002] A low-voltage switch cabinet is a device used to control, distribute, and protect circuits, and is usually used in industrial and commercial power systems. The low-voltage switch cabinet is used to operate low-voltage circuits, generally working in the range below 1000V, and can provide various functions and protection measures to ensure the safe operation and effective management of the power system.

[0003] Chinese Utility Model Patent Publication No.: CN 219513578 U, discloses: a new type of low-voltage switch cabinet. In this new type of low-voltage switch cabinet, through the sleeve in the lifting structure, the vertical cylinder is gradually and slowly rotated, so that the vertical cylinder moves up and down on the outer wall of the first screw rod, thereby causing the position of multiple cross plates to move, and then driving the position of the vertical plate to move. Then, external bolts are used to install electrical components on the front of the vertical plate, avoiding connection punches, ensuring the internal installation of the switch cabinet, and ensuring the normal use of the switch cabinet. However, the rotation of the vertical cylinder is relatively difficult, resulting in the operation of moving the position of the cross plate being difficult to achieve, and the structure is relatively complex and not convenient for installation.
