[0003] The above technical solution, through the design of the installation component, rotates the adjustment handle to move the fixed clamp block, thereby clamping and fixing the electric energy meter, thereby avoiding the need to use tools to remove the bolts when repairing and installing the electric energy meter. The disassembly and assembly are extremely cumbersome, resulting in reduced work efficiency. When the electric energy meter is damaged and needs to be replaced, the size and width of the new electric energy meter is inconsistent with the size and width of the original electric energy meter, that is, it is smaller than the size of the above-mentioned fastening cross bar, which makes it impossible to clamp.
