Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal wrenches, in particular to a novel hexagonal wrench. Background Art

[0002] Hexagonal wrenches are a common type of wrench. They apply force to screws through torque, greatly reducing the force required by the user and making it easy to loosen or tighten screws. When tightening a screw, the hexagonal wrench and the screw have six force-bearing surfaces, which are fully stressed and not easily damaged. Therefore, they have become an indispensable hand tool in industrial manufacturing and maintenance.

[0003] At present, most of the hexagonal wrenches on the market use a T-shaped handle to make it easier for workers to control the tightening or disassembly force. For example, a double-arm combined hexagonal wrench disclosed in Chinese patent publication No. CN212527533U, however, since the rotating rod and the connecting rod are perpendicular to each other and the angle between the rotating rod and the connecting rod cannot be changed, the hexagonal wrench occupies a large storage space when carried, making it inconvenient to carry.
