When tightening the nuts on the bolts, construction workers usually need to stand on scaffolding or other lifting vehicles and hold electric wrenches or manual wrenches to perform the construction. During the construction, it is necessary to fix the hexagonal head of the bolt to be locked with one hand and use an electric wrench or a manual wrench with the other hand to twist the nut on the bolt to be locked, so as to achieve the purpose of fixing the bolt to be locked.
