[0002] With the popularization of power systems, electricity has become an indispensable part of people's daily lives, and the demand for electricity has increased dramatically. Therefore, the construction of distribution lines is particularly important. However, in the construction of distribution lines, it is necessary to tighten bolts of various sizes and specifications. Workers need to change wrenches of different specifications multiple times according to the size of the bolts for tightening, which results in low installation efficiency and inconvenience. Moreover, distribution lines usually require crossarms to be installed and maintained at high altitudes, so workers can often only tighten the screws on one side of the crossarm. As a result, it is difficult to rotate the screws and nuts at the same time, so workers need to use both hands to fix the screws and nuts on both sides of the crossarm at the same time, which consumes a lot of manpower and is difficult to operate. Moreover, when faced with large-sized crossarms, it is difficult for one person to tighten the bolts, and two people are required to tighten the bolts, which is inefficient. Summary of the Invention
