[0002] Power engineering refers to engineering related to the production, transmission and distribution of electric energy. In a broad sense, it also includes engineering that uses electricity as power and energy in various fields. It can also be understood as the expansion of power transmission and transformation projects. Large-scale power systems integrate power generation, transmission, transformation, distribution and consumption into an organic whole, becoming the physical engineering system with the widest spatial span, strict time coordination and extremely complex hierarchical division of labor in the social material production sector. The construction operation of power engineering is called power construction. In the process of power construction, safety protection operations are required, and protective fences are a common safety protection mechanism in power construction.

[0003] A Chinese patent with publication number CN220301923U proposes a power construction fence. The operator pulls the two bases to effectively adjust the position of the guardrail, and then the position of the arc block can be directly lifted. The arc block effectively drives the position of the plug block to be lifted. Under the joint action of the expansion block, handle, and cylindrical block, the arc block effectively promotes the position of the expansion block to expand, effectively improving the stability of the device. Although the above method can improve the stability of the device, it not only requires bending over to adjust the position of the expansion block at the bottom, but also requires pulling up the arc blocks on both sides, which makes it inconvenient to use and difficult for one person to operate.
