[0002] As the name implies, high and low voltage distribution cabinets are power distribution equipment used for power distribution, control, metering, and connecting cables in the power supply system. Generally, high-voltage switch cabinets are used in power supply bureaus and substations, and then the low-voltage side is led out through electrical equipment to the low-voltage distribution cabinet, and the low-voltage distribution cabinet is then connected to each power distribution panel, control box, and switch box for power consumption.

[0003] During the use of the distribution cabinet, it will inevitably be subjected to impact forces. These impact forces may cause the connections of the electrical components inside the distribution cabinet to become loose, resulting in poor contact, increased resistance, heat generation, and even short circuits. At the same time, the impact forces are likely to cause physical damage to precision electronic components, affecting their normal functions and even leading to failures in the entire distribution cabinet system. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
