This method limits the mobility of the power supply and cannot meet the work needs of special scenarios (such as remote areas or construction sites). When the equipment location is beyond the range of the power harness, it is necessary to readjust the work layout or use an extension cord, which increases the complexity and inconvenience of operation.
