Then, you can repair the high-voltage switchgear. By plugging and fixing the T-type wrench and the hexagonal socket head, the length of the hexagonal wrench can be extended, eliminating the disadvantage of adding a force rod to ordinary hexagonal wrenches, and reducing the risk of equipment damage caused by excessive force by maintenance personnel. At the same time, both ends of the T-type wrench crossbar are covered with insulating rubber layers to reduce the risk of electric shock for maintenance personnel.

[0015] 3. At the same time, one end of the hexagonal socket head adopts a square interface, which can be used with T-type wrenches and ratchet wrenches with ordinary sockets. The other end is designed with an external hexagon and can be used with ordinary hexagonal wrenches, which solves the tedious process of using multiple tools at the same time. It saves time and effort when repairing equipment and greatly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
